                         MFA Mortgage Investments, Inc.
          Announces Third Quarter Dividend of $0.28 and Earnings Update

      MFA Mortgage Investments, Inc. (NYSE:MFA) announced today that its Board
of Directors declared a quarterly dividend of $0.28 per share of common stock
for the third quarter of 2003. The dividend will be paid on October 31, 2003 to
stockholders of record on September 30, 2003.


      Stewart Zimmerman, Chairman, President and Chief Executive Officer of MFA,
stated, "MFA's third quarter dividend of $0.28 per share is consistent with the
dividends per share declared during the first two quarters of 2003. During the
first half of 2003, in an effort to maintain a relatively stable dividend rate,
MFA declared aggregate dividends per share of $0.56, which was less than
earnings per share of $0.63 during the same period. While MFA's earnings on a
GAAP basis exceeded its dividend during the first two quarters of 2003, we now
expect, based on existing market conditions and performance of the portfolio to
date, that third quarter earnings per share will be in the range of
approximately $0.19 to $0.22. The two primary reasons that earnings are expected
to be less than the dividend are, first, rapid prepayments of the mortgages
underlying our MBS portfolio resulting in an accelerated amortization of the
related purchase premiums and, second, in an action taken to better maintain our
long term value and earnings, MFA utilized a reduced level of financial leverage
during a portion of the third quarter. Based on the significant decline in the
Mortgage Bankers Association refinancing index, we believe that prepayments and
the resulting premium amortization expense should decline resulting in a
positive impact on fourth quarter earnings."

      MFA's strategy is to generate a high level of income through leveraged
investment in a portfolio of high-quality adjustable-rate mortgage-backed
securities. As of June 30, 2003, approximately 99% of MFA's assets consisted of
mortgage-backed securities and related receivables issued or guaranteed as to
principal or interest by an agency of the U.S. government or a federally
chartered corporation, such as Fannie Mae, Freddie Mac and Ginnie Mae, high
quality mortgage-backed securities rated "AAA" by at least one nationally
recognized rating agency and cash. MFA's policy is to maintain an
assets-to-equity ratio of less than 11 to 1.



      When used in this press release or other written or oral communications,
statements which are not historical in nature, including those containing words
such as "anticipate," "estimate," "should," "expect," "believe," "intend" and
similar expressions are intended to identify "forward-looking statements" for
purposes of Section 27A of the Securities Act of 1933, as amended, and Section
21E of the Securities Exchange Act of 1934, as amended, and as such may involve
known and unknown risks, uncertainties and assumptions. These forward-looking
statements are subject to various risks and uncertainties, including, but not
limited to, those relating to: changes in the prepayment rates on the mortgage
loans securing MFA's MBS; changes in short-term interest rates and the market
value of MFA's MBS; changes in government regulations affecting MFA's business;
MFA's ability to maintain its qualification as a REIT for federal income tax
purposes; MFA's ability to use borrowings to finance its assets; and risks
associated with investing in real estate, including changes in business
conditions and the general economy. These risks, uncertainties and factors could
cause MFA's actual results to differ materially from those projected in any
forward-looking statements it makes. All forward-looking statements speak only
as the date they are made and MFA does not undertake, and specifically
disclaims, any obligation to update or revise any forward-looking statements to
reflect events or circumstances after the date of such statements.
