                  CAUTION REGARDING FORWARD-LOOKING STATEMENTS

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/or Brookfield Investment Management Inc.
("Brookfield" or the "Sub-Advisor") and their 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/or Sub-Advisor and
their respective representatives only as of the date hereof. We undertake no
obligation to publicly revise or update these forward-looking statements to
reflect events and circumstances that arise after the date hereof.

                        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 Notes to
Financial Statements 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.

                            HOW TO READ THIS REPORT

This report contains information that may help you evaluate your investment. 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
Fund, you may obtain an understanding of how the market environment affected the
Fund's performance. The statistical information that follows may help you

It is important to keep in mind that the opinions expressed by personnel of

                     FIRST TRUST MORTGAGE INCOME FUND (FMY)
                  SEMI-ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                 APRIL 30, 2012


Dear Shareholders:

I am pleased to present you with the semi-annual report for your investment in
First Trust Mortgage Income Fund (the "Fund").


The report you hold contains detailed information about your investment; a
portfolio commentary from the Fund's management team that provides a recap of
the period; a performance analysis and a market and Fund outlook. Additionally,
you will find the Fund's financial statements for the period this report covers.
I encourage you to read this document and discuss it with your financial
advisor. A successful investor is also typically a knowledgeable one, as we have
found to be the case at First Trust.

First Trust remains committed to being a long-term investor and investment
manager and to bringing you quality financial solutions regardless of market ups
and downs. We have always believed, as I have written previously, that there are
two ways to attain success in reaching your financial goals: staying invested in
quality products and having a long-term investment horizon. We are committed to
this approach in the products we manage or supervise and offer to investors.

As you know, First Trust offers a variety of products that we believe could fit
many financial plans to help investors seeking long-term investment success. We
encourage you to talk to your advisor about the other investments First Trust
offers that might also fit your financial goals and to discuss those goals with
your advisor regularly so that he or she can help keep you on track.

First Trust will continue to make available up-to-date information about your
investments so you and your financial advisor are current on any First Trust
investments you own. We value our relationship with you, and thank you for the
opportunity to assist you in achieving your financial goals. I look forward to
the remainder of 2012 and to the next edition of your Fund's report.

Sincerely,

/s/ James A. Bowen

                                   COMMENTARY

FIRST TRUST MORTGAGE INCOME FUND

The First Trust Mortgage Income Fund's (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 pursues its objectives by investing
primarily in MBS representing part ownership in a pool of either residential or
commercial mortgage loans that, in the opinion of the Fund's Sub-Advisor, offer
an attractive combination of credit quality, yield and maturity. These
securities may be issued by government agencies or by private originators or
issuers, generally in the form of pass-through certificates, collateralized
mortgage obligations, residential mortgage-backed securities ("RMBS") or
commercial mortgage-backed securities ("CMBS"). The Fund may leverage to an
aggregate amount of up to 33.33% of the Fund's Managed Assets.(1) The Fund uses
leverage primarily through the use of repurchase agreements.

MARKET RECAP AND OUTLOOK

Securitized products performed well during the six-month period ended April 30,
2012, with "risk on" being the dominant theme. Trading activity was brisk for
the period as large amounts of supply met strong demand from insurance companies
and money managers. Supply included the last of Maiden Lane II, the Fed's
special purpose vehicle ("SPV") that purchased


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

(1) The Fund's Managed Assets are the 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.


                                                                        Page 3

                       PORTFOLIO COMMENTARY - (CONTINUED)
--------------------------------------------------------------------------------

AIG's structured assets during the 2008 crisis. Although issuance of RMBS
continued to be light, there were three new issue deals announced in the first
quarter, two with new prime collateral and one with re-performing subprime
collateral. CMBS issuance continued its recovery with $4 billion in new deals
this quarter.

Economic signs have been stronger in the U.S., especially as warm weather seems
to have pulled forward some of the consumption typically associated with a
second quarter spring thaw. Unemployment continues to fall and consumer
confidence is rising. Given the data and minutes from the Federal Open Market
Committee meeting, a third round of Fed bond buying, so-called "QE3", now seems
unlikely. Government policy remains accommodative and the low-yield environment
is drawing investors toward higher-yielding sectors such as RMBS and CMBS.
European news was generally mixed but the strong uptake of Long Term Refinancing
Operations II buoyed European markets and kept global investors feeling bullish.
This bullish sentiment has also caused yields to converge as the premium for
riskier assets has narrowed, which has increased our preference for stability
and income.

From a real estate fundamental perspective, our current projection for home
prices is a further decline of 6.2% for the 2012 year-end. This is a reduction
from our 9.2% decline projection at year-end. As we approach a nadir in the
national averages, we expect to see more regional real estate markets tighten
and for strategic default to look less appealing to underwater borrowers.

More than 90% of new mortgages, including refinancing, are now guaranteed by
Fannie Mae, Freddie Mac or Ginnie Mae, and so any changes to government programs
can be an important driver of performance. Based on the published score card
memo, we now believe that the Federal Housing Finance Agency will begin
attempting to combine Fannie Mae and Freddie Mac and to sell first loss
protection in some future RMBS transactions. We also expect continued increases
in Ginnie Mae's insurance premiums as this is the only source of income to
replenish its dwindling reserve fund. These dynamics work against the White
House's policies expanding credit access. On the margin this will most likely
result in a stalemate and a low chance of greatly expanded credit.

Last quarter we posted positive returns in securitized products on improving
forecasts for collateral performance and lower-required yields from investors.
These dynamics are still intact now; therefore, we continue to remain optimistic
for returns. With a contraction in risk premiums, we remain focused on stability
and income. We believe bonds with these characteristics will be the first choice
for more conventional investors dipping a toe back into a market that may have
burned them not long ago. By contrast, more volatile bonds can rally more with a
"risk on" market; however, if their fundamental risks remain unresolved, it will
be difficult to harvest the paper gain. For these reasons, we continue to
emphasize senior prime RMBS, CMBS and seasoned Manufactured Housing.

PERFORMANCE ANALYSIS

For the six-month period ended April 30, 2012, the Fund had a total return(2) of
1.74% based on net asset value ("NAV"). For the period, the Fund traded from a
premium to NAV of 2.77% to a premium to NAV of 12.15%, resulting in a total
return2 of 11.08% based on market price. During the period, the Fund's
benchmark, the Barclays Capital U.S. MBS: Agency Fixed Rate MBS Index, returned
2.13%.

Over the course of the period, primary purchases for the Fund were investment
grade fixed-coupon CMBS and hybrid coupon non-Agency RMBS. We swapped a portion
of the Fund's exposure to Agency MBS derivatives as we repositioned to reduce
prepayment risk as interest rates fell. The purchases were funded with existing
cash, repaid principal on existing holdings and sales. In total, approximately
$4.9 million in senior non-Agency RMBS, $1.1 million in senior CMBS and $2
million of Agency derivatives were purchased.

With the portfolio close to the limit of below "A" grade allocation, we mostly
purchased bonds above the "A" grade during the past six months. In seeking bonds
with stable yield profiles, a sector we find particularly attractive is senior
prime RMBS.

We also prefer the most senior bonds in CMBS purchases as these bonds tend to
have considerable credit enhancement to avoid losses, and consequently have high
investment-grade ratings. When spreads on these bonds widen, we see an
opportunity to pick up spread to Agencies with more price upside potential.
Manufactured Housing is similarly remote from principal loss and with higher
spreads, although it is slower to find price appreciation in an improving
market.


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

(2) Total return is based on the combination of reinvested dividend, capital
    gains and return of capital distributions, if any, at prices obtained by the
    Dividend Reinvestment Plan and changes in NAV 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 less
    than one year. Past performance is not indicative of future results.

                       PORTFOLIO COMMENTARY - (CONTINUED)
--------------------------------------------------------------------------------

Currently, the leverage of the Fund is relatively low at 22.09%, as of April 30,
2012, given that the Fund may utilize leverage in an amount up to 33.33% of
Managed Assets. Where our overall budget for risk warrants it and when the
return opportunities are compelling, we are likely to increase leverage in an
attempt to improve returns. In periods of stability this may be an especially
important tool.

An important factor impacting the return of the Fund relative to its benchmarks
was the Fund's use of financial leverage through the use of bank borrowings. The
Fund uses leverage because its managers believe that, over time, leverage
provides opportunities for additional income and total return for common
shareholders. However, the use of leverage also can expose common shareholders
to additional volatility. For example, as the prices of securities held by the
Fund decline, the negative impact of the evaluation changes on common share net
asset value and common shareholder total return is magnified by the use of
leverage. Conversely, leverage may enhance common share returns during periods
when the prices of securities held by the Fund generally are rising. Leverage
had a positive impact on the performance of the Fund over this reporting period.

DISCLOSURE

Fixed-income investing entails credit risks and interest rate risks. When
interest rates rise, bond prices generally fall, and the Fund's share prices can
fall. Investments in below-investment-grade ("high-yield" or "junk") bonds are
more at risk of default and are subject to liquidity risk. Mortgage-backed
securities are subject to prepayment risk.

                        FIRST TRUST MORTGAGE INCOME FUND
                           APRIL 30, 2012 (UNAUDITED)


                              1. FUND DESCRIPTION

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
("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 in mortgage-backed securities that, in the
opinion of Brookfield Investment Management Inc. ("Brookfield" or the
"Sub-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 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 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.

A. PORTFOLIO VALUATION:

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 in accordance with valuation procedures
adopted by the Fund's Board of Trustees, and in accordance with provisions of
the 1940 Act. The Fund's securities will be valued as follows:

      U.S. Government securities, mortgage-backed securities ("MBS"),
      asset-backed securities ("ABS") and other debt securities are valued on
      the basis of valuations provided by dealers who make markets in such
      securities or by an independent 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.


Debt securities having a remaining maturity of sixty days or less when purchased
are valued at cost adjusted for amortization of premiums and accretion of
discounts.

In the event that the pricing service or dealer does not provide a valuation or
the valuations received are deemed unreliable, the Fund's Board of Trustees has
designated First Trust Advisors L.P. ("First Trust") to use a fair value method
to value the Fund's securities. Additionally, if events occur after the close of
the principal markets for certain securities (e.g., domestic debt and foreign
securities) that could materially affect the Fund's NAV, First Trust may use a
fair value method to value the Fund's securities. The use of fair value pricing
is governed by valuation procedures adopted by the Fund's Board of Trustees, and
in accordance with the provisions of the 1940 Act. As a general principle, the
fair value of a security is the amount which the Fund might reasonably expect to
receive for the security upon its current sale. However, in light of the
judgment involved in fair valuations, there can be no assurance that a fair
value assigned to a particular security will be the amount which the Fund might
be able to receive upon its current sale. Fair valuation of a security is based
on the consideration of all available information, 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;


                                                                        Page 17

                        FIRST TRUST MORTGAGE INCOME FUND
                           APRIL 30, 2012 (UNAUDITED)


      5)    the credit quality and cash flow of the issuer, based on the
            Sub-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 investments.

The inputs or methodology 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, 2012, is
included with the Fund's Portfolio of Investments.

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 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, 2012, the Fund had no when-issued,
delayed-delivery or forward purchase commitments.

C. REVERSE REPURCHASE AGREEMENTS:

Reverse repurchase agreements are utilized as leverage for the Fund. A reverse
repurchase agreement, although structured as a sale and repurchase obligation,
acts as a financing under which Fund assets are pledged as collateral to secure
a short-term loan. Generally, the other party to the agreement makes the loan in
an amount equal to a percentage of the market value of the pledged collateral.
At the maturity of the reverse repurchase agreement, the loan will be repaid and
the collateral will correspondingly be received back by the Fund. While used as
collateral, the assets continue to pay principal and interest which are for the
benefit of the Fund.

                        FIRST TRUST MORTGAGE INCOME FUND
                           APRIL 30, 2012 (UNAUDITED)

Information for the six months ended April 30, 2012:

     Maximum amount outstanding during the period.................. $22,993,750
     Average amount outstanding during the period*................. $22,143,157
     Average Common Shares outstanding during the period...........   4,075,582
     Average debt per Common Share outstanding during the period...       $5.43

* The average amount outstanding during the period was calculated by adding the
borrowings at the end of each day and dividing the sum by the number of days in
the six months ended April 30, 2012.

During the six months ended April 30, 2012, the interest rates ranged from 0.31%
to 1.65%, with a weighted average interest rate of 0.83%, on borrowings by the
Fund under reverse repurchase agreements, which had interest expense that
aggregated $94,482.

D. 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. These securities are
identified on the Portfolio of Investments.

E. 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 or IO security and
all of the principal is distributed to holders of another type of security known
as a principal-only or PO security. These securities are identified on the
Portfolio of Investments.

F. INTEREST-ONLY SECURITIES:

An interest-only security ("IO security") is the interest-only portion of a MBS
that receives some or all of the interest portion of the underlying MBS 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 are identified on the Portfolio of
Investments.

G. 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 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
income tax regulations, which may differ from accounting principles generally
accepted in the United States of America. 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,
2011 was as follows:

Distributions paid from:

Ordinary income....................................       $8,244,891
Capital gain.......................................              --
Return of capital..................................              --



                                                                       Page 19

                                                     ===============

H. INCOME AND OTHER 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 or 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 98.2% of the Fund's taxable income
exceeds the distributions from such taxable income for the calendar year.

The Fund intends to utilize provisions of the federal income tax laws which
allow it to carry realized capital losses forward for eight years following the
year of the loss and offset such loss against any future realized capital gains.
The Fund is subject to certain limitations under 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. At October 31, 2011, the
Fund had a capital loss carryforward for federal income tax purposes of
$6,209,176, expiring as follows:

                    EXPIRATION DATE           AMOUNT
                    October 31, 2014       $ 2,859,304
                    October 31, 2017       $ 1,927,985
                    October 31, 2018       $ 1,421,887

During the taxable year ended October 31, 2011, the Fund utilized capital loss
carryforwards in the amount of $897,649.

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 ending 2008, 2009,
2010 and 2011 remain open to federal and state audit. As of April 30, 2012,
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.

I. EXPENSES:

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

J. ACCOUNTING PRONOUNCEMENTS:

In May 2011, the Financial Accounting Standards Board ("FASB") issued ASU
2011-04, "Amendments to Achieve Common Fair Value Measurement and Disclosure
Requirements in U.S. GAAP and IFRSs," modifying Topic 820, "Fair Value
Measurements and Disclosures." At the same time, the International Accounting
Standards Board ("IASB") issued International Financial Reporting Standard
("IFRS") 13, "Fair Value Measurement." The objective of the FASB and IASB is
convergence of their guidance on fair value measurements and disclosures.
Specifically, the ASU requires reporting entities to disclose (i) the amounts of
any transfers between Level 1 and Level 2, and the reasons for the transfers,
(ii) for Level 3 fair value measurements, quantitative information about
significant unobservable inputs used, (iii) a description of the valuation
processes used by the reporting entity, and (iv) a narrative description of the
sensitivity of the fair value measurement to changes in unobservable inputs if a
change in those inputs might result in a significantly higher or lower fair
value measurement. The effective date of the ASU is for interim and annual
periods beginning after December 15, 2011. Management is currently evaluating
the impact of the updated standard on the Fund's financial statements.

(the 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.

Brookfield serves as the Fund's sub-advisor and manages the Fund's portfolio
subject to First Trust's supervision. The Sub-Advisor receives a portfolio
management fee of 0.50% of Managed Assets that is paid monthly by First Trust
from its investment advisory fee.

BNY Mellon Investment Servicing (US) Inc. serves as the Fund's Administrator,
Fund Accountant and Transfer Agent in accordance with certain fee arrangements.
The Bank of New York Mellon serves as the Fund's Custodian in accordance with

Chief Financial Officer and Chief Accounting Officer of the Fund.

Effective January 1, 2012, each Trustee who is not an officer or employee of
First Trust, any sub-advisor or any of their affiliates ("Independent Trustee")
is paid an annual retainer of $125,000 per year and an annual per fund fee of
$4,000 for each closed-end fund or other actively managed fund and $1,000 for
each index fund in the First Trust Fund Complex. The fixed annual retainer is
allocated pro rata among each fund in the First Trust Fund Complex based on net
assets. Prior to January 1, 2012, each Independent Trustee received an annual
retainer of $10,000 per trust for the first 14 trusts of the First Trust Fund
Complex and an annual retainer for $7,500 per trust for each additional trust in
the First Trust Fund Complex. The annual retainer was allocated equally among
each of the trusts.

Additionally, the Lead Independent Trustee is paid $15,000 annually, the
Chairman of the Audit Committee is paid $10,000 annually, and each of the
Chairmen of the Nominating and Governance Committee and the Valuation Committee
is paid $5,000 annually to serve in such capacities, with such compensation
allocated pro rata among each fund in the First Trust Fund Complex based on net
assets. Prior to January 1, 2012, the annual amounts paid were $10,000, $5,000
and $2,500, respectively. Trustees are reimbursed for travel and out-of-pocket
expenses in connection with all meetings. The Lead Independent Trustee and each
Committee chairman will serve two-year terms before rotating to serve as
chairman of another committee or as Lead Independent Trustee. The officers and
"Interested" Trustee receive no compensation from the Fund for acting in such
capacities.

                      4. PURCHASES AND SALES OF SECURITIES

The cost of purchases of U.S. Government securities and non-U.S. Government
securities, excluding short-term investments, for the six months ended April 30,
2012 were $21,911,449 and $20,162,945, respectively. The proceeds from sales and
paydowns of U.S. Government securities and non-U.S. Government securities,
excluding short-term investments, for the six months ended April 30, 2012 were
$11,427,714 and $35,352,033, respectively.

                               5. INDEMNIFICATION

The Fund has a variety of indemnification obligations under contracts with its
service providers. The Fund's maximum exposure under these arrangements is
unknown. However, the Fund has not had prior claims or losses pursuant to these
contracts and expects the risk of loss to be remote.

                             6. 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.

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 or Sub-Advisor determines that it is temporarily

                                                                         Page 21

                           APRIL 30, 2012 (UNAUDITED)


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 or Sub-Advisor may take
temporary defensive positions.

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.

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 Sub-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.

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.

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.

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.

                              7. SUBSEQUENT EVENTS

Management has evaluated the impact of all subsequent events to the Fund through
the date the financial statements were issued, and has determined that there
were the following subsequent events:

On May 21, 2012, the Fund declared a dividend of $0.16 per share to Common
Shareholders of record on June 5, 2012, payable June 15, 2012.

On June 20, 2012, the Fund declared a dividend of $0.16 per share to Common
Shareholders of record on July 5, 2012, payable July 16, 2012.

On June 21, 2012, the Fund, Advisor and Sub-Advisor entered into a sales
agreement with JonesTrading whereby the Fund may offer and sell up to 1,000,000
Common Shares from time to time through JonesTrading as agent for the offer and
sale of the Common Shares. Sales of Common Shares pursuant to the sales
agreement may be made in negotiated transactions or transactions that are deemed
to be "at the market" as defined in Rule 415 under the Securities Act of 1933,
as amended, including sales made directly on the NYSE or sales made through a
market maker other than on an exchange, at an offering price equal to or in
excess of the net asset value per share of the Fund's Common Shares at the time
such Common Shares are initially sold. The Fund intends to use the net proceeds
from the sale of the Common Shares in accordance with its investment objectives
and policies.

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

                        FIRST TRUST MORTGAGE INCOME FUND
                           APRIL 30, 2012 (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.
