MFA Mortgage Investments, Inc.
Announces Second Quarter Dividend of $0.25

     MFA Mortgage Investments, Inc. (NYSE:MFA) announced today that its Board of Directors declared a quarterly dividend of $0.25 per share of common stock for the second quarter of 2004. The dividend will be paid on July 30, 2004 to stockholders of record on July 12, 2004.

     Stewart Zimmerman, MFA’s Chairman of the Board, Chief Executive Officer and President, stated, “As anticipated, prepayment speeds on MFA’s mortgage-backed securities (“MBS”) increased during the second quarter of 2004, primarily due to mortgage refinancings already in the pipeline as of the end of the first quarter. This higher prepayment level resulted in increased purchase premium amortization in the second quarter. MFA expects that higher interest rates during the second quarter should lead to a decline in prepayment speeds on its MBS portfolio, positively impacting purchase premium amortization expense in the third quarter. In the expectation of rising interest rates, MFA conservatively maintained a reduced level of assets during the quarter. Further, in anticipation of a continued uptrend in interest rates, MFA generally intends to maintain a conservative level of assets throughout the balance of 2004.”

     MFA seeks to generate income from investments in high-quality adjustable-rate MBS and other assets. At March 31, 2004, approximately 99% of MFA’s assets consisted of MBS guaranteed by an agency of the U.S. Government, such as Ginnie Mae, or a federally chartered corporation, such as Fannie Mae or Freddie Mac, other MBS rated “AAA” by Standard & Poor’s Corporation, MBS-related receivables and cash.
