Michael Strauss, Chairman and Chief Executive Officer commented, "During the
second quarter the company nearly completed the initial build-up of its mortgage
backed securities portfolio including adding $1.5 billion of self-originated
securities and purchasing additional securities. Today the portfolio consists of
$7.3 billion of mortgage-backed securities of which $2.6 billion were
self-originated and $4.7 billion were market purchased. Over the coming quarters
the company intends to replace many of the market bought securities it currently
holds with self-originated securities that are projected to produce higher
yields. Mortgage originations in the second quarter were strong, reaching $6.6
billion due to the company achieving record market share."

SECOND QUARTER OPERATING AND FINANCIAL HIGHLIGHTS
- -------------------------------------------------

During the second quarter, the company's net interest income was $20.1 million
while its average mortgage securities portfolio holdings were $4.8 billion and
the average amount of mortgages held in its inventory was $1.8 billion. Net
interest income is expected to increase in the third quarter as a result of the
company's larger portfolio, and its ongoing substitution of self-originated for
market bought securities. Mortgage production during the quarter grew 6.5%
compared to the second quarter of 2003 despite the fact that nationwide
originations declined 24.2% based on Fannie Mae's estimate. Of the $6.6 billion
of loans originated by the company, $1.3 billion were securitized and held, $4.2
billion were sold for cash, and $1.1 billion were added to loans held pending
sale or securitization. During the quarter, the company's gain on sale of
mortgage loans and mortgage-backed securities was $59.8 million. The company's
adoption of SAB 105 during the quarter resulted in a pre-tax reduction of gain
on sale of loans of $18.7 million.

In the second quarter the company's servicing related revenue was $8.2 million
as servicing benefited from higher servicing fees, slowing amortization of its
servicing asset and recovery of impairment of the servicing asset due to rising
interest rates. As of June 30, the notional amount of loans serviced was $10.2
billion, while the servicing asset had a market value of $145.1 million, was
carried at a book value of $141.8 million, and had a temporary impairment
reserve of $9.2 million. Total income for the second quarter was $33.5 million
compared to $26.9 million during the second quarter of 2003, while earnings per
fully diluted share was $0.83 compared to $1.55 for the second quarter last
year. Earnings per share would have been $0.27 higher in the second quarter of
2004 if not for the adoption of SAB 105.

During the second quarter, the company continued to focus on high credit-quality
assets. On June 30, 2004 35.5% of the company's assets were Fannie Mae or
Freddie Mac obligations, while 61.6% were rated AAA and 1.2% were rated AA and
1.7% were rated A, BBB or unrated, by Standard & Poors. The company also
continued to focus on adjustable and hybrid adjustable rate mortgages. On June
30 the portfolio consisted of 56.2% 5/1 ARMs, 23.0% 3/1 ARMs, and 20.8% ARMs
with an initial reset less than 3 years after origination. On June 30, the
average cost of the portfolio was 100.8%, while its average life was 3.8 years,
and its net duration was negative 0.04 years.

OTHER SECOND QUARTER HIGHLIGHTS
- -------------------------------

      o     American Home Mortgage Securities LLC securitized approximately $1.4
            billion of adjustable rate loans. In addition, the company
            securitized $0.7 billion of adjustable rate loans through Fannie Mae
            and Freddie Mac's guarantee programs. The company purchased and held
            $1.5 billion of these self-originated securities for its portfolio.

      o     The company began issuing commercial paper to fund its mortgage
            inventory. By funding a portion of its inventory with commercial
            paper, the company expects its borrowing costs to be reduced. As of
            June 30, the company has $1.0 billion of commercial paper
            outstanding.

      o     The company issued $53.8 million of its Class A Preferred Stock
            which settled in July 2004.

      o     On June 4, the company's Board of Directors declared a dividend of
            $0.61 per share payable on July 14, to shareholders of record June
            30.

OUTLOOK
- -------

During the second half of 2004, the company expects to earn increased net
interest income due to the increased size of its mortgage backed securities
portfolio, and due to the ongoing substitution of self-originated assets for
market bought assets. The company also expects that mortgage originations will
fall throughout the second half with a consequent reduction in loan production
income. Finally, the company projects that higher servicing fees and slowing
amortization will cause its servicing assets to contribute to income through the
remainder of the year.

Based on its projections, the Company reaffirms its 2004 earnings guidance of
$3.25 to $3.40 per share. In addition, the company's continues to support its
dividend policy of $0.61 per share per quarter, subject to ongoing review by its
Board of Directors based on business conditions and the company's financial
condition. The company's dividends policy does not constitute an obligation to
pay dividends which only occurs when its Board of Directors declares a dividend.

ACQUISITION OF CERTAIN ORIGINATION BRANCHES FROM WASHINGTON MUTUAL
- ------------------------------------------------------------------

On July 28 the company announced it signed a definitive agreement with
Washington Mutual, Inc. and its subsidiaries to acquire certain residential
mortgage home loan centers and associated satellite offices in 18 states.
Approximately 500 employees are currently supporting these home loan centers and
associated satellite offices with the vast majority being sales professionals
focused on retail loan originations. The company is currently in the process of
hiring a number of the Washington Mutual employees who work at the acquired home
loan centers.

Under the terms of the acquisition, American Home will assume Washington
Mutual's lease obligations and will purchase certain fixed assets in the
acquired offices. The acquisition will be funded from current cash reserves and
is expected to close on August 2, 2004.

Michael Strauss commented, "Over the last five years American Home has achieved
noteworthy success acquiring significant origination assets at advantageous
terms. The strategic rationale behind this acquisition is to expand our retail
channel in and increase the generation of self originated adjustable rate loans.
In addition, these offices are expected to offer additional efficiencies of
scale for supporting our nationwide branch network."
