This report contains certain forward-looking statements within the meaning of
the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934,
as amended. Forward-looking statements include statements regarding the goals,
beliefs, plans or current expectations of First Trust Advisors L.P. ("First
Trust" or the "Advisor") and its respective representatives, taking into account
the information currently available to them. Forward-looking statements include
all statements that do not relate solely to current or historical fact. For
example, forward-looking statements include the use of words such as
"anticipate," "estimate," "intend," "expect," "believe," "plan," "may,"
"should," "would" or other words that convey uncertainty of future events or
outcomes.

Forward-looking statements involve known and unknown risks, uncertainties and
other factors that may cause the actual results, performance or achievements of
First Trust Mortgage Income Fund (the "Fund") to be materially different from
any future results, performance or achievements expressed or implied by the
forward-looking statements. When evaluating the information included in this
report, you are cautioned not to place undue reliance on these forward-looking
statements, which reflect the judgment of the Advisor and its respective
representatives only as of the date hereof. We undertake no obligation to

                        PERFORMANCE AND RISK DISCLOSURE

There is no assurance that the Fund will achieve its investment objectives. The
Fund is subject to market risk, which is the possibility that the market values
of securities owned by the Fund will decline and that the value of the Fund
shares may therefore be less than what you paid for them. Accordingly, you can
lose money by investing in the Fund. See "Risk Considerations" in the Additional
Information section of this report for a discussion of certain other risks of
investing in the Fund.

Performance data quoted represents past performance, which is no guarantee of
future results, and current performance may be lower or higher than the figures
shown. For the most recent month-end performance figures, please visit
http://www.ftportfolios.com or speak with your financial advisor. Investment
returns, net asset value and common share price will fluctuate and Fund shares,
when sold, may be worth more or less than their original cost.

The Advisor may periodically provide additional information on Fund performance
on the Fund's webpage at http://www.ftportfolios.com.

                            HOW TO READ THIS REPORT

the Fund. It includes details about the Fund and presents data and analysis that
provide insight into the Fund's performance and investment approach.

By reading the portfolio commentary by the portfolio management team of the

SHAREHOLDER LETTER
--------------------------------------------------------------------------------

                     FIRST TRUST MORTGAGE INCOME FUND (FMY)
                  SEMI-ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                 APRIL 30, 2017

Dear Shareholders:

Thank you for your investment in the First Trust Mortgage Income Fund (the
"Fund").

The year 2016 was a historic year all over the world. Many will remember some of
the events that occurred during the year: from the Brexit vote in the UK to
leave the European Union, to the results of the U.S. Presidential Election which
seemed unlikely at the beginning of 2016, to the first World Series Championship
for the Chicago Cubs in 108 years!

First Trust Advisors L.P. ("First Trust") is pleased to provide you with this
semi-annual report which contains detailed information about your investment.
Additionally, First Trust has compiled the Fund's financial statements for you
to review. We encourage you to read this report and discuss it with your
financial advisor.

On November 8, 2016, Donald J. Trump was elected to become the 45th president in
our country's history. As I write this, he has just hit his 100th day in office,
always a historic marker for pundits, politicians, and voters. While no one has
a crystal ball and the ability to predict how the Trump administration will
shape the United States (and the world), there is no doubt that his populist
message resonated for many Americans. His message of improving lives for the
"average" American, while reducing the size and scope of the federal government,
also won him millions of votes. Many of his supporters believe that with his
background in business, Trump will make policy changes that will continue to
grow the economy and spur stock markets even higher. Many analysts predicted the
Dow Jones Industrial Average would hit a new benchmark, 20,000, in the first
days of the New Year. It took until January 25, 2017, but the Dow finally traded
over 20,000 on that day. On March 1, 2017, the Dow went past 21,000, a new
record. As with all change and a new administration, only time will tell where
our economy and the markets will go.

As of December 31, 2016, the S&P 500(R) Index (the "Index") was up 11.96% for
the year, on a total return basis, as measured by Bloomberg. As of April 30,
2017, the Index was up 7.16% (calendar year-to-date). The current bull market
(measuring from March 9, 2009 through April 28, 2017) is the second longest in
history, but lags the longest bull market by 4.17 years, according to Bespoke
Investment Group. We remain bullish on the economy, but continue to have a
long-term perspective. We believe investors should think long-term as well,
since no one can predict volatility and the inevitable ups and downs that occur
in the market.

Thank you for giving First Trust the opportunity to be a part of your investment
plan. We value our relationship with you and will continue our relentless focus
on bringing the types of investments that we believe could help you reach your
financial goals.

Sincerely,

/s/ James A. Bowen

James A. Bowen
Chairman of the Board of Trustees
Chief Executive Officer of First Trust Advisors L.P.

                                   COMMENTARY

FIRST TRUST MORTGAGE INCOME FUND

The First Trust Mortgage Income Fund's ("FMY" or the "Fund") primary investment
objective is to seek a high level of current income. As a secondary objective,
the Fund seeks to preserve capital. The Fund will pursue its objectives by
investing primarily in mortgage-backed securities ("MBS") representing part
ownership in a pool of either residential or commercial mortgage loans that, in
the opinion of the Fund's investment advisor, offer an attractive combination of
credit quality, yield and maturity. There can be no assurance the Fund will
achieve its investment objectives. The Fund may not be appropriate for all
investors.

MARKET RECAP

During the six-month period ended April 30, 2017, the U.S. bond market
experienced declines and higher rates across the maturity spectrum, led by the
5-year Treasury, which saw its yield increase by 51 basis points ("bps"). The
long end outperformed the 5-year Treasury, with the yield curve bear flattening
of 14bps. Fixed-rate Agency MBS spreads widened approximately 9bps over the
six-month period, to close at 24bps Treasury option-adjusted spread ("OAS"), as
measured using the BofA Merrill Lynch US Mortgage Backed Index calculations.

PERFORMANCE ANALYSIS

For the six-month period ended April 30, 2017, the Fund returned 2.54% based on
net asset value ("NAV") and 3.32% on market price. During the same time period,
the Fund's benchmark, the Bloomberg Barclays U.S. MBS Index returned -0.61%. The
Fund outperformed the index by 3.15% net of fees for the period.

Over the six-month time period, the Fund maintained a very defensive duration in
the portfolio relative to the benchmark. This was a key driver of outperformance
over the six-month period as the broader U.S. bond market experienced
significant declines. An additional key contributor to outperformance was the
legacy Non-Agency Residential MBS sector. The portfolio management team
increased the overall allocation to the sector, which then experienced spread
tightening. The team also began to deploy significant excess cash reserves into
more stable, defensive Agency MBS cash flows which helped to generate interest
income and stabilize the overall duration distribution across the yield curve
profile of the strategy.

HISTORICAL EARNINGS

Income is recognized for financial statement purposes in accordance with
accounting principles generally accepted in the United States of America ("U.S.
GAAP"). Over the past two fiscal years ended October 31, 2015 and 2016, and the
semi-annual period ended April 30, 2017, U.S. GAAP basis gross income has been
lower than in previous fiscal years, as it has been impacted by yield
adjustments on certain legacy interest only securities due to changes in
prepayments and estimated future cash flows. Additionally, the U.S. GAAP basis
yield adjustments during the periods referenced had no impact on the Fund's net
asset value, its total return, or the tax characterization of its distributions.
For a per share breakdown of income and distributions for the past five and a
half fiscal years, please see the Financial Highlights on page 15 of this
semi-annual report.

MARKET OUTLOOK

The tail end of 2016 saw the Federal Reserve ("Fed") raise the Federal Funds
overnight target rate by 25bps and then another 25bps at the March 2017 meeting.
Additionally, the broader U.S. fixed-income markets saw significant sell-offs in
the immediate aftermath of the U.S. presidential election, with the new
administration promising deregulation, tax cuts, and infrastructure spending.
After the second Fed hike in March, the market began to rally on the back of the
markets wavering confidence in the new administration's ability to push
meaningful pro-growth agenda through. We do expect that the Fed will continue to
increase the overnight funding target rate with another two hikes for the
balance of 2017, and then address the deleveraging of the $4.5 trillion Fed
balance sheet. We believe the deleveraging will increase volatility in the U.S.
markets, put upward pressure on yields and lead to wider spreads across all U.S.
fixed-income markets.

Given our views and outlook on the markets, we plan to continue to manage the
Fund defensively versus the Fund's benchmark from a duration standpoint, while
maintaining our ongoing strategy of barbelling our duration across the yield
curve, with higher yielding, spread assets allocated primarily to defensive
short maturities. We continue to be bearish on the benchmark, and as such,
anticipate maintaining an underweight on the MBS basis.

(a)   Floating or variable rate security. The interest rate shown reflects the
      rate in effect at April 30, 2017.

(b)   This security, sold within the terms of a private placement memorandum, is
      exempt from registration upon resale under Rule 144A of the Securities Act
      of 1933, as amended (the "1933 Act"), and may be resold in transactions
      exempt from registration, normally to qualified institutional buyers.
      Pursuant to procedures adopted by the Fund's Board of Trustees, this
      security has been determined to be liquid by First Trust Advisors L.P.
      ("First Trust" or the "Advisor"), the Fund's advisor. Although market
      instability can result in periods of increased overall market illiquidity,
      liquidity for each security is determined based on security specific
      factors and assumptions, which require subjective judgment. At April 30,
      2017, securities noted as such amounted to $6,882,406, or 10.55% of net
      assets.

(c)   Inverse floating rate instrument. The interest rate shown reflects the
      rate in effect at April 30, 2017.

(d)   This security, sold within the terms of a private placement memorandum, is
      exempt from registration upon resale under Rule 144A of the 1933 Act, and
      may be resold in transactions exempt from registration, normally to
      qualified institutional buyers (see Note 2C - Restricted Securities in the
      Notes to Financial Statements).

(e)   Aggregate cost for financial reporting purposes, which approximates the
      aggregate cost for federal income tax purposes. As of April 30, 2017, the
      aggregate gross unrealized appreciation for all securities in which there
      was an excess of value over tax cost was $1,723,234 and the aggregate
      gross unrealized depreciation for all securities in which there was an
      excess of tax cost over value was $3,745,422.

IO    Interest-Only Security - Principal amount shown represents par value on
      which interest payments are based.

----------------------------


(a)   Effective September 19, 2016, the portfolio management of the Fund
      transitioned to the First Trust Mortgage Securities Team. Schroder
      Investment Management North America Inc. acquired the portfolio management
      team of Brookfield Investment Management Inc. ("Brookfield"), previously
      responsible for the portfolio management of the Fund, resulting in the
      automatic termination of the investment sub-advisory agreement among
      Brookfield, First Trust and the Fund. In connection with the change in
      portfolio management, First Trust agreed to lower the investment
      management fee payable by the Fund to a rate of 0.85% of the Fund's
      managed assets, a decrease from the Fund's previous investment management
      fee of 1.00% of the Fund's managed assets.

(b)   Total return is based on the combination of reinvested dividend, capital
      gain and return of capital distributions, if any, at prices obtained by
      the Dividend Reinvestment Plan, and changes in net asset value per share
      for net asset value returns and changes in Common Share Price for market
      value returns. Total returns do not reflect sales load and are not
      annualized for periods of less than one year. Past performance is not
      indicative of future results.

(c)   The Fund received reimbursements from Brookfield in the amount of $1,180
      and $5,310 for the years ended October 31, 2014 and 2013, respectively.
      The reimbursements from Brookfield represent less than $0.01 per share and
      had no effect on the Fund's total return.

(d)   Annualized.

                     FIRST TRUST MORTGAGE INCOME FUND (FMY)
                           APRIL 30, 2017 (UNAUDITED)

                                1. ORGANIZATION

First Trust Mortgage Income Fund (the "Fund") is a diversified, closed-end
management investment company organized as a Massachusetts business trust on
February 22, 2005, and is registered with the Securities and Exchange Commission
(the "SEC") under the Investment Company Act of 1940, as amended (the "1940
Act"). The Fund trades under the ticker symbol FMY on the New York Stock
Exchange ("NYSE").

The Fund's primary investment objective is to seek a high level of current
income. As a secondary objective, the Fund seeks to preserve capital. The Fund
pursues these objectives by investing primarily in mortgage-backed securities
that, in the opinion of First Trust Advisors L.P. ("First Trust" or the
"Advisor"), offer an attractive combination of credit quality, yield and
maturity. There can be no assurance that the Fund's investment objectives will
be achieved. The Fund may not be appropriate for all investors.

                       2. SIGNIFICANT ACCOUNTING POLICIES

The Fund is considered an investment company and follows accounting and
reporting guidance under Financial Accounting Standards Board ("FASB")
Accounting Standards Codification ("ASC") Topic 946, "Financial
Services-Investment Companies." The following is a summary of significant
accounting policies consistently followed by the Fund in the preparation of its
financial statements. The preparation of financial statements in accordance with
accounting principles generally accepted in the United States of America ("U.S.
GAAP") requires management to make estimates and assumptions that affect the
reported amounts and disclosures in the financial statements. Actual results
could differ from those estimates.

The net asset value ("NAV") of the Common Shares of the Fund is determined
daily, as of the close of regular trading on the NYSE, normally 4:00 p.m.
Eastern time, on each day the NYSE is open for trading. If the NYSE closes early
on a valuation day, the NAV is determined as of that time. Domestic debt
securities and foreign securities are priced using data reflecting the earlier
closing of the principal markets for those securities. The NAV per Common Share
is calculated by dividing the value of all assets of the Fund (including accrued
interest and dividends), less all liabilities (including accrued expenses,
dividends declared but unpaid and any borrowings of the Fund), by the total
number of Common Shares outstanding.

The Fund's investments are valued daily at market value or, in the absence of
market value with respect to any portfolio securities, at fair value. Market
value prices represent last sale or official closing prices from a national or
foreign exchange (i.e., a regulated market) and are primarily obtained from
third-party pricing services. Fair value prices represent any prices not
considered market value prices and are either obtained from a third-party
pricing service or are determined by the Advisor's Pricing Committee, in
accordance with valuation procedures adopted by the Fund's Board of Trustees,
and in accordance with provisions of the 1940 Act. Investments valued by the
Advisor's Pricing Committee, if any, are footnoted as such in the footnotes to
the Portfolio of Investments. The Fund's investments are valued as follows:

      U.S. government securities, mortgage-backed securities, asset-backed
      securities and other debt securities are fair valued on the basis of
      valuations provided by dealers who make markets in such securities or by a
      third-party pricing service approved by the Fund's Board of Trustees,
      which may use the following valuation inputs when available:

      1)    benchmark yields;

      2)    reported trades;

      3)    broker/dealer quotes;

      4)    issuer spreads;

      5)    benchmark securities;

      6)    bids and offers; and

      7)    reference data including market research publications.

      Exchange-traded futures contracts are valued at the closing price in the
      market where such contracts are principally traded. If no closing price is
      available, exchange-traded futures contracts are fair valued at the mean
      of their most recent bid and asked price, if available, and otherwise at
      their closing bid price.

      Fixed income and other debt securities having a remaining maturity of
      sixty days or less when purchased are fair valued at cost adjusted for
      amortization of premiums and accretion of discounts (amortized cost),
      provided the Advisor's Pricing Committee has determined that the use of
      amortized cost is an appropriate reflection of fair value given market and
      issuer-specific conditions existing at the time of the determination.
      Factors that may be considered in determining the appropriateness of the
      use of amortized cost include, but are not limited to, the following:

      1)    the credit conditions in the relevant market and changes thereto;

      2)    the liquidity conditions in the relevant market and changes thereto;

                     FIRST TRUST MORTGAGE INCOME FUND (FMY)
                           APRIL 30, 2017 (UNAUDITED)

      3)    the interest rate conditions in the relevant market and changes
            thereto (such as significant changes in interest rates);

      4)    issuer-specific conditions (such as significant credit
            deterioration); and

      5)    any other market-based data the Advisor's Pricing Committee
            considers relevant. In this regard, the Advisor's Pricing Committee
            may use last-obtained market-based data to assist it when valuing
            portfolio securities using amortized cost.

Certain securities may not be able to be priced by pre-established pricing
methods. Such securities may be valued by the Fund's Board of Trustees or its
delegate, the Advisor's Pricing Committee, at fair value. These securities
generally include, but are not limited to, restricted securities (securities
which may not be publicly sold without registration under the Securities Act of
1933, as amended (the "1933 Act")) for which a third-party pricing service is
unable to provide a market price; securities whose trading has been formally
suspended; a security whose market or fair value price is not available from a
pre-established pricing source; a security with respect to which an event has
occurred that is likely to materially affect the value of the security after the
market has closed but before the calculation of the Fund's NAV or make it
difficult or impossible to obtain a reliable market quotation; and a security
whose price, as provided by the third-party pricing service, does not reflect
the security's fair value. As a general principle, the current fair value of a
security would appear to be the amount which the owner might reasonably expect
to receive for the security upon its current sale. When fair value prices are
used, generally they will differ from market quotations or official closing
prices on the applicable exchanges. A variety of factors may be considered in
determining the fair value of such securities, including, but not limited to,
the following:

      1)    the fundamental business data relating to the issuer;

      2)    an evaluation of the forces which influence the market in which
            these securities are purchased and sold;

      3)    the type, size and cost of security;

      4)    the financial statements of the issuer;

      5)    the credit quality and cash flow of the issuer, based on the
            Advisor's or external analysis;

      6)    the information as to any transactions in or offers for the
            security;

      7)    the price and extent of public trading in similar securities (or
            equity securities) of the issuer/borrower, or comparable companies;

      8)    the coupon payments;

      9)    the quality, value and salability of collateral, if any, securing
            the security;

     10)    the business prospects of the issuer, including any ability to
            obtain money or resources from a parent or affiliate and an
            assessment of the issuer's management;

     11)    the prospects for the issuer's industry, and multiples (of earnings
            and/or cash flows) being paid for similar businesses in that
            industry; and

     12)    other relevant factors.

The Fund is subject to fair value accounting standards that define fair value,
establish the framework for measuring fair value and provide a three-level
hierarchy for fair valuation based upon the inputs to the valuation as of the
measurement date. The three levels of the fair value hierarchy are as follows:

      o     Level 1 - Level 1 inputs are quoted prices in active markets for
            identical investments. An active market is a market in which
            transactions for the investment occur with sufficient frequency and
            volume to provide pricing information on an ongoing basis.

      o     Level 2 - Level 2 inputs are observable inputs, either directly or
            indirectly, and include the following:

            o     Quoted prices for similar investments in active markets.

            o     Quoted prices for identical or similar investments in markets
                  that are non-active. A non-active market is a market where
                  there are few transactions for the investment, the prices are
                  not current, or price quotations vary substantially either
                  over time or among market makers, or in which little
                  information is released publicly.

            o     Inputs other than quoted prices that are observable for the
                  investment (for example, interest rates and yield curves
                  observable at commonly quoted intervals, volatilities,
                  prepayment speeds, loss severities, credit risks, and default
                  rates).

            o     Inputs that are derived principally from or corroborated by
                  observable market data by correlation or other means.

      o     Level 3 - Level 3 inputs are unobservable inputs. Unobservable
            inputs may reflect the reporting entity's own assumptions about the
            assumptions that market participants would use in pricing the
            investment.

The inputs or methodologies used for valuing investments are not necessarily an
indication of the risk associated with investing in those investments. A summary
of the inputs used to value the Fund's investments as of April 30, 2017, is
included with the Fund's Portfolio of Investments.


                                                                         Page 17

                           APRIL 30, 2017 (UNAUDITED)

B. SECURITIES TRANSACTIONS AND INVESTMENT INCOME

Securities transactions are recorded as of the trade date. Realized gains and
losses from securities transactions are recorded on the identified cost basis.
Interest income is recorded daily on the accrual basis. Amortization of premiums
and the accretion of discounts are recorded using the effective interest method.

The Fund invests in interest-only securities. For these securities, if there is
a change in the estimated cash flows, based on an evaluation of current
information, then the estimated yield is adjusted. Additionally, if the
evaluation of current information indicates a permanent impairment of the
security, the cost basis of the security is written down and a loss is
recognized. Debt obligations may be placed on non-accrual status and the related
interest income may be reduced by ceasing current accruals and writing off
interest receivables when the collection of all or a portion of interest has
become doubtful based on consistently applied procedures. A debt obligation is
removed from non-accrual status when the issuer resumes interest payments or
when collectability of interest is reasonably assured.

Securities purchased or sold on a when-issued, delayed-delivery or forward
purchase commitment basis may have extended settlement periods. The value of the
security so purchased is subject to market fluctuations during this period. The
Fund maintains liquid assets with a current value at least equal to the amount
of its when-issued, delayed-delivery or forward purchase commitments until
payment is made. At April 30, 2017, the Fund had no when-issued,
delayed-delivery or forward purchase commitments.

C. RESTRICTED SECURITIES

The Fund invests in restricted securities, which are securities that may not be
offered for public sale without first being registered under the 1933 Act. Prior
to registration, restricted securities may only be resold in transactions exempt
from registration under Rule 144A under the 1933 Act, normally to qualified
institutional buyers. As of April 30, 2017, the Fund held restricted securities
as shown in the following table that the Advisor has deemed illiquid pursuant to
procedures adopted by the Fund's Board of Trustees. Although market instability
can result in periods of increased overall market illiquidity, liquidity for
each security is determined based on security-specific factors and assumptions,
which require subjective judgment. The Fund does not have the right to demand
that such securities be registered. These securities are valued according to the
valuation procedures as stated in the Portfolio Valuation note (Note 2A) and are
not expressed as a discount to the carrying value of a comparable unrestricted
security. There are no unrestricted securities with the same maturity dates and
yields for these issuers.



                                                                                                             % OF

D. FUTURES CONTRACTS

The Fund may purchase or sell (i.e., is long or short) exchange-listed futures
contracts to hedge against changes in interest rates (interest rate risk).
Futures contracts are agreements between the Fund and a counterparty to buy or
sell a specific quantity of an underlying instrument at a specified price and at
a specified date. Depending on the terms of the contract, futures contracts are
settled either through physical delivery of the underlying instrument on the
settlement date or by payment of a cash settlement amount on the settlement
date. Open futures contracts can also be closed out prior to settlement by
entering into an offsetting transaction in a matching futures contract. If the
Fund is not able to enter into an offsetting transaction, the Fund will continue
to be required to maintain margin deposits on the futures contract. When the
contract is closed or expires, the Fund records a realized gain or loss equal to
the difference between the value of the contract at the time it was opened and
the value at the time it was closed or expired. This gain or loss is included in
"Net realized gain (loss) on futures" on the Statement of Operations.

Upon entering into a futures contract, the Fund must deposit funds, called
margin, with its custodian in the name of the clearing broker equal to a
specified percentage of the current value of the contract. Open futures contacts
are marked to market daily with the change in value recognized as a component of
"Net change in unrealized appreciation (depreciation) on futures" on the
Statement of Operations. Pursuant to the contract, the Fund agrees to receive
from or pay to the broker an amount of cash equal to the daily fluctuation in
value of the contract. Such receipts or payments are known as variation margin
and are included in "Variation margin payable or receivable" on the Statement of
Assets and Liabilities.

If market conditions change unexpectedly, the Fund may not achieve the
anticipated benefits of the futures contract and may realize a loss. The use of
futures contracts involves the risk of imperfect correlation in movements in the
price of the futures contracts, interest rates and the underlying instruments.

                     FIRST TRUST MORTGAGE INCOME FUND (FMY)
                           APRIL 30, 2017 (UNAUDITED)

E. INVERSE FLOATING-RATE SECURITIES

An inverse floating-rate security is one where the coupon is inversely indexed
to a short-term floating interest rate multiplied by a specific factor. As the
floating rate rises, the coupon is reduced. Conversely, as the floating rate
declines, the coupon is increased. The price of these securities may be more
volatile than the price of a comparable fixed-rate security. These instruments
are typically used to enhance the yield of the portfolio and have the effect of
creating leverage. These securities, if any, are identified on the Portfolio of
Investments.

F. STRIPPED MORTGAGE-BACKED SECURITIES

Stripped Mortgage-Backed Securities are created by segregating the cash flows
from underlying mortgage loans or mortgage securities to create two or more new
securities, each with a specified percentage of the underlying security's
principal or interest payments. Mortgage securities may be partially stripped so
that each investor class receives some interest and some principal. When
securities are completely stripped, however, all of the interest is distributed
to holders of one type of security known as an interest-only security ("IO
Security") and all of the principal is distributed to holders of another type of
security known as a principal-only security. These securities, if any, are
identified on the Portfolio of Investments.

G. INTEREST-ONLY SECURITIES

An IO Security is the interest-only portion of a mortgage-backed security that
receives some or all of the interest portion of the underlying mortgage-backed
security and little or no principal. A reference principal value called a
notional value is used to calculate the amount of interest due to the IO
Security. IO Securities are sold at a deep discount to their notional principal
amount. Generally speaking, when interest rates are falling and prepayment rates
are increasing, the value of an IO Security will fall. Conversely, when interest
rates are rising and prepayment rates are decreasing, generally the value of an
IO Security will rise. These securities, if any, are identified on the Portfolio
of Investments.

H. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

The Fund will distribute to holders of its Common Shares monthly dividends of
all or a portion of its net income after the payment of interest and dividends
in connection with leverage, if any. Distributions of any net long-term capital
gains earned by the Fund are distributed at least annually. Distributions will
automatically be reinvested into additional Common Shares pursuant to the Fund's
Dividend Reinvestment Plan unless cash distributions are elected by the
shareholder.

Distributions from income and capital gains are determined in accordance with
federal income tax regulations, which may differ from U.S. GAAP. Certain capital
accounts in the financial statements are periodically adjusted for permanent
differences in order to reflect their tax character. These permanent differences
are primarily due to the varying treatment of income and gain/loss on portfolio
securities held by the Fund and have no impact on net assets or NAV per share.
Temporary differences, which arise from recognizing certain items of income,
expense and gain/loss in different periods for financial statement and tax
purposes, will reverse at some point in the future.

The tax character of distributions paid during the fiscal year ended October 31,
2016, was as follows:

Distributions paid from:

Ordinary income...................................   $    2,266,839
Capital gain......................................               --
Return of capital.................................        1,567,096

As of October 31, 2016, the distributable earnings and net assets on a tax basis
were as follows:

Undistributed ordinary income.....................   $           --
Undistributed capital gains.......................               --
                                                     --------------
Total undistributed earnings......................               --
Accumulated capital and other losses..............       (4,993,262)
Net unrealized appreciation (depreciation)........       (3,564,982)
                                                     --------------
Total accumulated earnings (losses)...............       (8,558,244)
Other.............................................               --
Paid-in capital...................................       73,995,082
                                                     --------------
Net assets........................................   $   65,436,838
                                                     ==============

I. INCOME TAXES

The Fund intends to continue to qualify as a regulated investment company by
complying with the requirements under Subchapter M of the Internal Revenue Code
of 1986, as amended, which includes distributing substantially all of its net
investment income and net realized gains to shareholders. Accordingly, no
provision has been made for federal and state income taxes. However, due to the
timing and amount of distributions, the Fund may be subject to an excise tax of
4% of the amount by which approximately 98% of the Fund's taxable income exceeds
the distributions from such taxable income for the calendar year.


                                                                         Page 19

                     FIRST TRUST MORTGAGE INCOME FUND (FMY)
                           APRIL 30, 2017 (UNAUDITED)

Under the Regulated Investment Company Modernization Act of 2010 (the "Act"),
net capital losses arising in taxable years after December 22, 2010, may be
carried forward indefinitely, and their character is retained as short-term
and/or long-term losses. Previously, net capital losses were carried forward for
up to eight years and treated as short-term losses. As a transition rule, the
Act requires that post-enactment net capital losses be used before pre-enactment
net capital losses. At October 31, 2016, the Fund had pre-enactment net capital
losses for federal income tax purposes of $3,349,872. At October 31, 2016, the
Fund had post-enactment net capital losses for federal income tax purposes of
$1,643,390 to be carried forward indefinitely. The pre-enactment net capital
losses for federal income tax purposes will expire as follows:

                EXPIRATION DATE             AMOUNT
                October 31, 2017       $ 1,927,985
                October 31, 2018       $ 1,421,887

During the taxable year ended October 31, 2016, the Fund did not utilize any
pre-enactment capital loss carryforwards.

The Fund is subject to certain limitations under the U.S. tax rules on the use
of capital loss carryforwards and net unrealized built-in losses. These
limitations apply when there has been a 50% change in ownership.

The Fund is subject to accounting standards that establish a minimum threshold
for recognizing, and a system for measuring, the benefits of a tax position
taken or expected to be taken in a tax return. Taxable years ended 2013, 2014,
2015 and 2016 remain open to federal and state audit. As of April 30, 2017,
management has evaluated the application of these standards to the Fund and has
determined that no provision for income tax is required in the Fund's financial
statements for uncertain tax positions.

J. EXPENSES

The Fund will pay all expenses directly related to its operations.

K. NEW AND AMENDED FINANCIAL REPORTING RULES AND FORMS

On October 13, 2016, the SEC adopted new rules and forms, and amended existing
rules and forms. The new and amended rules and forms are intended to modernize
the reporting of information provided by funds and to improve the quality and
type of information that funds provide to the SEC and investors. The new and
amended rules and forms will be effective for the First Trusts funds, including
the Fund, for reporting periods beginning on and after June 1, 2018. Management
is evaluating the new and amended rules and forms to determine the impact to the
Fund.

L. NEW ACCOUNTING PRONOUNCEMENT

In December 2016, FASB released Accounting Standards Update ("ASU") 2016-19 that
makes technical changes to various sections of the ASC, including Topic 820,
Fair Value Measurement. The changes to Topic 820 are intended to clarify the
difference between a valuation approach and a valuation technique. The changes
to ASC 820-10-50-2 require a reporting entity to disclose, for Level 2 and Level
3 fair value measurements, a change in either or both a valuation approach and a
valuation technique and the reason(s) for the change. The changes to Topic 820
are effective for fiscal years, and interim periods within those fiscal years,
beginning after December 15, 2016. At this time, management is evaluating the
implications of the ASU and has not yet determined its impact on the financial
statements and disclosures.

3. INVESTMENT ADVISORY FEE, AFFILIATED TRANSACTIONS AND OTHER FEE ARRANGEMENTS

First Trust, the investment advisor to the Fund, is a limited partnership with
one limited partner, Grace Partners of DuPage L.P., and one general partner, The
Charger Corporation. The Charger Corporation is an Illinois corporation
controlled by James A. Bowen, Chief Executive Officer of First Trust. First
Trust is responsible for the ongoing monitoring of the Fund's investment
portfolio, managing the Fund's business affairs and providing certain
administrative services necessary for the management of the Fund. For these
investment management services, First Trust is entitled to a monthly fee
calculated at an annual rate of 0.85% of the Fund's Managed Assets (the average
daily total asset value of the Fund minus the sum of the Fund's liabilities
other than the principal amount of borrowings or reverse repurchase agreements,
if any). First Trust also provides fund reporting services to the Fund for a
flat annual fee in the amount of $9,250.

BNY Mellon Investment Servicing (US) Inc. ("BNYM IS") serves as the Fund's
transfer agent in accordance with certain fee arrangements. As transfer agent,
BNYM IS is responsible for maintaining shareholder records for the Fund. The
Bank of New York Mellon ("BNYM") serves as the Fund's administrator, fund
accountant, and custodian in accordance with certain fee arrangements. As
administrator and fund accountant, BNYM is responsible for providing certain
administrative and accounting services to the Fund, including maintaining the
Fund's books of account, records of the Fund's securities transactions, and
certain other books and records. As custodian, BNYM is responsible for custody
of the Fund's assets. BNYM IS and BNYM are subsidiaries of The Bank of New York
Mellon Corporation, a financial holding company.

varies based on whether the fund is a closed-end or other actively managed fund,
or is an index fund.

Additionally, the Lead Independent Trustee and the Chairmen of the Audit
Committee, Nominating and Governance Committee and Valuation Committee are paid
annual fees to serve in such capacities, with such compensation allocated pro
rata among each fund in the First Trust Fund Complex based on net assets.
Independent Trustees are reimbursed for travel and out-of-pocket expenses in
connection with all meetings. The Lead Independent Trustee and Committee
Chairmen rotate every three years. The officers and "Interested" Trustee receive
no compensation from the Fund for acting in such capacities.

ADDITIONAL INFORMATION
--------------------------------------------------------------------------------

                     FIRST TRUST MORTGAGE INCOME FUND (FMY)
                           APRIL 30, 2017 (UNAUDITED)

                           DIVIDEND REINVESTMENT PLAN

If your Common Shares are registered directly with the Fund or if you hold your
Common Shares with a brokerage firm that participates in the Fund's Dividend
Reinvestment Plan (the "Plan"), unless you elect, by written notice to the Fund,
to receive cash distributions, all dividends, including any capital gain
distributions, on your Common Shares will be automatically reinvested by BNY
Mellon Investment Servicing (US) Inc. (the "Plan Agent"), in additional Common
Shares under the Plan. If you elect to receive cash distributions, you will
receive all distributions in cash paid by check mailed directly to you by the
Plan Agent, as the dividend paying agent.

If you decide to participate in the Plan, the number of Common Shares you will
receive will be determined as follows:

      (1)   If Common Shares are trading at or above net asset value ("NAV") at
            the time of valuation, the Fund will issue new shares at a price
            equal to the greater of (i) NAV per Common Share on that date or
            (ii) 95% of the market price on that date.

      (2)   If Common Shares are trading below NAV at the time of valuation, the
            Plan Agent will receive the dividend or distribution in cash and
            will purchase Common Shares in the open market, on the NYSE or
            elsewhere, for the participants' accounts. It is possible that the
            market price for the Common Shares may increase before the Plan
            Agent has completed its purchases. Therefore, the average purchase
            price per share paid by the Plan Agent may exceed the market price
            at the time of valuation, resulting in the purchase of fewer shares
            than if the dividend or distribution had been paid in Common Shares
            issued by the Fund. The Plan Agent will use all dividends and
            distributions received in cash to purchase Common Shares in the open
            market within 30 days of the valuation date except where temporary
            curtailment or suspension of purchases is necessary to comply with
            federal securities laws. Interest will not be paid on any uninvested
            cash payments.

You may elect to opt-out of or withdraw from the Plan at any time by giving
written notice to the Plan Agent, or by telephone at (866) 340-1104, in
accordance with such reasonable requirements as the Plan Agent and the Fund may
agree upon. If you withdraw or the Plan is terminated, you will receive a
certificate for each whole share in your account under the Plan, and you will
receive a cash payment for any fraction of a share in your account. If you wish,
the Plan Agent will sell your shares and send you the proceeds, minus brokerage
commissions.

The Plan Agent maintains all Common Shareholders' accounts in the Plan and gives
written confirmation of all transactions in the accounts, including information
you may need for tax records. Common Shares in your account will be held by the
Plan Agent in non-certificated form. The Plan Agent will forward to each
participant any proxy solicitation material and will vote any shares so held
only in accordance with proxies returned to the Fund. Any proxy you receive will
include all Common Shares you have received under the Plan.

There is no brokerage charge for reinvestment of your dividends or distributions
in Common Shares. However, all participants will pay a pro rata share of
brokerage commissions incurred by the Plan Agent when it makes open market
purchases.

Automatically reinvesting dividends and distributions does not mean that you do
not have to pay income taxes due upon receiving dividends and distributions.
Capital gains and income are realized although cash is not received by you.
Consult your financial advisor for more information.

If you hold your Common Shares with a brokerage firm that does not participate
in the Plan, you will not be able to participate in the Plan and any dividend
reinvestment may be effected on different terms than those described above.

The Fund reserves the right to amend or terminate the Plan if in the judgment of
the Board of Trustees the change is warranted. There is no direct service charge
to participants in the Plan; however, the Fund reserves the right to amend the
Plan to include a service charge payable by the participants. Additional
information about the Plan may be obtained by writing BNY Mellon Investment
Servicing (US) Inc., 301 Bellevue Parkway, Wilmington, Delaware 19809.

                              RISK CONSIDERATIONS

Risks are inherent in all investing. The following summarizes some of the risks
that should be considered for the Fund. For additional information about the
risks associated with investing in the Fund, please see the Fund's prospectus
and statement of additional information, as well as other Fund regulatory
filings.

FIXED-INCOME SECURITIES RISK: Debt securities, including high yield securities,
are subject to certain risks, including: (i) issuer risk, which is the risk that
the value of fixed-income securities may decline for a number of reasons which
directly relate to the issuer, such as management performance, financial
leverage and reduced demand for the issuer's goods and services or, in the case
of asset-backed issuers, a decline in the value and/or cash flows of the
underlying assets; (ii) reinvestment risk, which is the risk that income from
the Fund's portfolio will decline if the proceeds from matured, traded or called
bonds are invested at market interest rates that are below the Fund portfolio's
current earnings rate; and (iii) credit risk, which is the risk that a security
in the Fund's portfolio will decline in price or the issuer fails to make
interest payments when due because the issuer of the security experiences a
decline in its financial status.

INTEREST RATE RISK: The Fund may also hold MBS which are Stripped
Mortgage-Backed Securities, IO securities and PO securities. Generally speaking,
when interest rates are falling and prepayment rates are increasing, the value
of a PO security will rise and the value of an IO security will fall.
Conversely, when interest rates are rising and prepayment rates are decreasing,
generally the value of a PO security will fall and the value of an IO security
will rise.

INVESTMENT AND MARKET RISK: An investment in the Fund's Common Shares is subject
to investment risk, including the possible loss of the entire principal
invested. An investment in Common Shares represents an indirect investment in
the securities owned by the Fund. The value of these securities, like other
market investments, may move up or down, sometimes rapidly and unpredictably.
Common Shares at any point in time may be worth less than the original
investment, even after taking into account the reinvestment of Fund
distributions. Security prices can fluctuate for several reasons including the
general condition of the securities market, or when political or economic events
affecting the issuers occur, including the risk that borrowers do not pay their
mortgages. When the Advisor determines that it is temporarily unable to follow
the Fund's investment strategy or that it is impractical to do so (such as when
a market disruption event has occurred and trading in the securities is
extremely limited or absent), the Advisor may take temporary defensive
positions.

LEVERAGE RISK: Borrowings up to 33-1/3% (or such other percentage as permitted
by law) of Fund assets (including the amount borrowed) less liabilities other
than borrowings may be utilized in the Fund. Leverage may be used for investment
purposes and to meet cash requirements. The leveraged capital structure creates
special risks not associated with unleveraged funds having similar investment
objectives and policies. These include the possibility of higher volatility of
the NAV of the Fund. Reverse repurchase agreements are used to leverage the
Fund's assets. Reverse repurchase agreements are subject to the risks that the
market value of the Fund's securities sold may decline below the price of the
securities the Fund is obligated to repurchase, and that the securities may not
be returned to the Fund. From time to time the amount of the leverage may be
changed in response to actual or anticipated changes in interest rates or the
value of the Fund's investment portfolio. There can be no assurance that the
leverage strategies will be successful.

MORTGAGE AND ASSET-BACKED SECURITIES RISK: The value of mortgage and
asset-backed securities can fall if the owners of the underlying mortgages or
other obligations pay off their mortgages or other obligations sooner than
expected, which could happen when interest rates fall or for other reasons.
Mortgage and asset-backed securities are also subject to extension risk, which
is the risk that rising interest rates could cause mortgages or other
obligations underlying the securities to be prepaid more slowly than expected,
which would, in effect, convert a short or medium duration mortgage or
asset-backed security into a longer duration security, increasing its
sensitivity to interest rate changes and causing its price to decline. Mortgage
and asset-backed security values may also be affected by the creditworthiness of
the servicing agent for the pool, the originator of the loans or receivables or
entities providing for any credit enhancement.


                                                                         Page 23





--------------------------------------------------------------------------------
ADDITIONAL INFORMATION (CONTINUED)
--------------------------------------------------------------------------------

                     FIRST TRUST MORTGAGE INCOME FUND (FMY)
                           APRIL 30, 2017 (UNAUDITED)

A mortgage backed security may be negatively affected by the quality of the
mortgages underlying such security and the structure of its issuer. For example,
if a mortgage underlying a certain mortgage backed security defaults, the value
of that security may decrease.

Mortgage backed securities issued by a private issuer, such as commercial
mortgage backed securities, generally entail greater risk than obligations
directly or indirectly guaranteed by the U.S. government or a government
sponsored entity.

PREPAYMENT RISK: If borrowers prepay their mortgage loans at rates that are
faster than expected, this results in prepayments that are faster than expected
on MBS. These faster than expected prepayments may adversely affect the Fund's
profitability, particularly if the prepayments must be reinvested at market
interest rates that are below the Fund portfolio's current earnings rate.

Moreover, the Fund may also hold MBS that are less affected by prepayments.
While the Advisor seeks to minimize prepayment risk to the extent practical,
they must balance prepayment risk against other risks and the potential returns
of each investment in selecting investments. No strategy can completely insulate
the Fund from prepayment risk.

SUBORDINATED DEBT RISK: A portion of the Fund's Managed Assets may be invested
in subordinated classes of MBS, including debt obligations issued by private
originators or issuers backed by residential mortgage loans and multi-class debt
or pass-through or pay-through securities backed by a mortgage loan or pool of
mortgage loans on commercial real estate. Such subordinated classes are subject
to a greater degree of non-payment risk than are senior classes of the same
issuer or agency.
