MFA Mortgage Investments, Inc.
Announces Second Quarter 2007 Dividend of $0.09

MFA Mortgage Investments, Inc. (NYSE:MFA) announced today that its Board of Directors declared a quarterly dividend of $0.09 per share of common stock for the second quarter of 2007. The dividend will be paid on July 31, 2007 to stockholders of record on July 13, 2007.

MFA’s primary focus is high quality, higher coupon hybrid and adjustable-rate MBS assets. At March 31, 2007, approximately 99% of MFA’s assets consisted of MBS issued or guaranteed by an agency of the U.S. government or a federally chartered corporation, other MBS rated “AAA” by Standard & Poor’s Corporation, MFA-related receivables and cash. The MBS in MFA’s portfolio are primarily adjustable-rate or hybrids, which have an initial fixed interest rate for a specified period of time and, thereafter, generally reset annually.

Stockholders interested in learning how to participate in MFA’s Discount Waiver, Direct Stock Purchase and Dividend Reinvestment Plan (the “Plan”) or receiving a Plan prospectus may do so by contacting Mellon Investor Services, the Plan administrator, at 1-866-249-2610 (toll free). For more information about the Plan, interested stockholders may also go to the website established for the Plan at www.melloninvestor.com or visit MFA’s website at www.mfa-reit.com.

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” within the meaning 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 interest rates and the market value of MFA’s MBS; changes in the prepayment rates on the mortgage loans securing MFA’s MBS; MFA’s ability to use borrowings to finance its assets; changes in government regulations affecting MFA’s business; MFA’s ability to maintain its qualification as a REIT for federal income tax purposes; and risks associated with investing in real estate assets, including changes in business conditions and the general economy. These and other risks, uncertainties and factors, including those described in reports that MFA files from time to time with the SEC, 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 of 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 occurring after the date of such statements.
