Melville, NY (April 28, 2004) -- American Home Mortgage Investment Corp. (NYSE:
AHH) today announced results for the first quarter ended March 31, 2004.

      o     Net earnings for the first quarter of 2004 were $21.2 million,
            compared to $16.3 million for the first quarter of 2003, an increase
            of 30.1%.

      o     Earnings per diluted share for the first quarter of 2004 was $0.70
            per share, compared to $0.96 per share for the first quarter of
            2003, a decrease of 27.1%.

      o     Book value per share rose to $18.59 at March 31, 2004, compared to
            $10.73 at March 31, 2003.

      o     Dividends per share for the first quarter was $0.55 compared to
            $0.10 for the first quarter of 2003.

Michael Strauss, Chairman and Chief Executive Officer, commented, "We are
pleased with the results from our first quarter. During the quarter, we worked
to build our portfolio of mortgage-backed securities and added $1.0 billion of
self-originated securities and $2.1 billion of purchased securities to our
holdings. On March 31, 2004, total mortgage backed securities held, including
ARM loans pending securitization, was $4.3 billion compared to $1.9 billion on
December 31, 2003. Holdings on April 26, 2004, were $5.7 billion. During the
quarter, the company also added to the capital deployed in its mortgage
securities holdings business through an equity offering of $359.3 million."

FIRST QUARTER HIGHLIGHTS
- ------------------------

During the quarter, the company continued to focus on its strategy of reducing
interest rate risk by attempting to match the duration of its assets to their
associated liabilities and hedges. The company's duration gap was less than one
month on both March 31 and April 26, and the value of the company's
mortgage-backed securities portfolio was not significantly impacted by falling
rates during the first quarter of 2004, or the subsequent recent increase in
interest rates. The company continues to hold primarily high credit quality
assets. Of its mortgage-backed securities holdings, 89.1% were either rated AAA
by Standard & Poor's or were obligations of Fannie Mae or Freddie Mac, while
9.1% were rated AA. During the quarter, the company's mortgage-backed securities
holdings average portfolio yield was 3.1%, while its average cost of funds and
hedges was 2.1%. The result was a net margin of 1.2%. The average cost of the
mortgage-backed securities held was 101.6 percent of their principal amount,
while the value of the mortgage-backed securities held was 102.5 percent of
their principal amount. The average amount of mortgage-backed securities held
during the quarter was $2.0 billion, while net interest income from those
holdings was $5.7 million.

The company's loan origination segment produced $4.4 billion of new loans during
the first quarter. This represents an increase of 2.3% compared to the first
quarter of 2003 and compares favorably to the trend in total U.S. originations
which declined 21.0% in the first quarter of 2004 compared to the first quarter
of 2003. Loan production in the first quarter of 2004 also compared favorably to
the fourth quarter of 2003 when the company originated $4.1 billion of loans.
During the first quarter of 2004, the company sold $3.4 billion of primarily
fixed rate loans to third parties and securitized and held $0.9 billion of
adjustable rate loans as long-term investments.

The company's servicing business experienced a loss during the first quarter of
2004 due to a decline in interest rates causing rapid amortization and
impairment of the company's servicing assets. Amortization and impairment was
$19.9 million pretax and created a tax benefit of $8.2 million, resulting in an
after-tax expense of $11.7 million. Given the current level of interest rates,
the company expects amortization to slow and expects to recover its impairment
reserve net of taxes in the second quarter of 2004.

During the first quarter of 2004, the company's book value increased primarily
as a result of its completed equity offering, and also as a result of income
exceeding dividends. Book value at the end of the quarter was $741 million or
$18.59 per share.

OUTLOOK
- -------

The company projects that its mortgage-backed securities holdings, including ARM
loans pending securitization, will increase to an average of $5.7 billion in the
second quarter of 2004 and $6.6 billion for the third and fourth quarters of
2004. The company expects to continue to attempt to match the duration of its
securities and their associated liabilities and hedges, and consequently
anticipates that the results from its securities holdings will not be
significantly affected by changing interest rates. The company expects its net
margin will incrementally increase approximately 40 basis points by 2004
year-end as the portion of its holdings which are self-originated grows.

The company expects that the recent rise and expected continued increases in
interest rates will significantly reduce its loan originations during the later
half of 2004 compared to anticipated originations for the second quarter.
Originations are projected to be approximately $6 billion during the second
quarter, $5 billion during the third quarter and $4 billion during the fourth
quarter. In addition, the company expects that second quarter origination
results will be diminished by its adoption of Staff Accounting Bulletin No. 105,
which replaces the industry's interpretation of FASB No. 133 in regards to
accounting for the value of mortgage application pipelines and the resulting
effect on the value of mortgage loans held for sale.

The company expects that the recent rise in interest rates will significantly
improve its results from servicing. Rising interest rates are expected to slow
amortization throughout the year. In addition, second quarter servicing results
are projected to benefit from a recovery of the impairment reserve associated
with the company's servicing assets. Servicing fee income is expected to
increase throughout 2004 as the company securitizes its ARM loan production and
holds the associated servicing contracts.

Based on its projections for the combined results from the company's mortgage
holdings, mortgage origination and mortgage servicing segments, the company is
raising its earnings guidance for the full year 2004 to $3.25 to $3.40 per
share.

DIVIDEND
- --------

The company sets its dividend policy based on its forecasts of earnings and cash
flow. The dividend policy may be changed at any time by the company's Board of
Directors and does not constitute an actual decision by the company to pay
dividends, which only occurs when dividends are actually declared. Based on the
company's forecasts, the company is increasing its dividend policy to a
quarterly rate of $0.61 or an annualized rate of $2.44 per fully diluted share.
