    Re:  ANNALY MORTGAGE MANAGEMENT, INC.
         WITHDRAWAL OF REGISTRATION STATEMENT ON FORM S-4 (FILE NO. 333-113480)

Ladies and Gentlemen:

         Pursuant to Rule 477  promulgated  under the Securities Act of 1933, as
amended  (the  "Securities  Act"),   Annaly  Mortgage   Management,   Inc.  (the
"Registrant")  hereby  respectfully  requests that the  Securities  and Exchange
Commission  (the  "Commission")  consent to the  withdrawal of the  Registrant's
registration  statement  on  Form  S-4  (Registration  No.  333-113480)  and all
exhibits thereto (collectively, the "Registration Statement").

         The  Registration  Statement,  which  was  originally  filed  with  the
Commission on March 10, 2004,  relates to the proposed  merger of a wholly owned
subsidiary  of  the  Registrant  and  Fixed  Income  Discount  Advisory  Company
("FIDAC"). The merger agreement originally contemplated that the shareholders of
FIDAC would receive an initial amount of registered  shares of the  Registrant's
common stock and contingent earn-out payments, also payable in registered shares
of  the  Registrant's  common  stock.  Accordingly,  the  Registrant  filed  the
Registration Statement submitting these matters to its stockholders.

         The  Registrant   subsequently  determined  that  it  would  not  issue
registered  shares in the  merger  but would seek its  shareholder  approval  on
Schedule 14A. The Registration  Statement has not been declared effective and no
securities were offered or sold pursuant to the Registration Statement.

         If you have any questions  with respect to this matter,  please contact
the  Registrant's  counsel,  R.  Nicholas  Singh of McKee  Nelson  LLP, at (202)
775-4134.

                                            Very truly yours,

                                            /s/ Michael A.J. Farrell
                                            Michael A.J. Farrell
