      On September 13, 2004, American Home Mortgage Investment Corp. (the

with the Company's presentation at the Lehman Conference is attached hereto as
Exhibit 99.1 and is incorporated herein by reference. The Company issued a press
release on September 7, 2004, announcing its presentation at the Lehman
Conference and how to access a replay of the presentation. A copy of the press
release is attached hereto as Exhibit 99.2 and is incorporated herein by
reference.

      The information in this Current Report on Form 8-K, including Exhibits
99.1 and 99.2 hereto, is being furnished and shall not be deemed "filed" for the
purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or
otherwise subject to the liabilities of that Section. The information in this
Current Report on Form 8-K will not be incorporated by reference into any
registration statement or other document filed by the Company under the
Securities Act of 1933, as amended, unless specifically identified therein as
being incorporated by reference. The furnishing of the information in this
Current Report on Form 8-K is not intended to, and does not, constitute a
determination or admission by the Company that the information in this Current

Regarding Forward-Looking Statements:

      This Current Report on Form 8-K, including Exhibit 99.1 incorporated by
reference herein, contains certain forward-looking statements within the meaning
of the federal securities laws. Some of the forward-looking statements can be
identified by the use of forward-looking words. Statements that are not
historical in nature, including the words "anticipate," "may," "estimate,"
"should," "seek," "expect," "plan," "believe," "intend," and similar words, or
the negatives of those words, are intended to identify forward-looking
statements. Statements that also contain a projection of revenues, earnings
(loss), capital expenditures, dividends, capital structure or other financial
terms are intended to be forward-looking statements. Certain statements
regarding the following particularly are forward-looking in nature: the
Company's business strategy; future performance, developments, market forecasts
or projected dividends; projected capital expenditures; and the Company's
expected future financial position. Forward-looking statements are subject to a
number of known and unknown factors, risks and uncertainties that may cause the
Company's actual results, performance or financial condition to be materially
different from any expectations of future results, performance or financial
position expressed or implied by such forward-looking statements. These factors
include, without limitation: the potential fluctuations in the Company's
operating results; the Company's need for a significant amount of cash to
operate its business; risks associated with the use of leverage; failure to
match the interest rates on the Company's borrowings with the interest rates on
the mortgage-backed securities it holds; failure to maintain the Company's
status as a real estate investment trust; general economic, political, market,
financial or legal conditions; and those risks and uncertainties discussed in
the Company's filings with the Securities and Exchange

                                      -2-


Commission. You are cautioned not to place undue reliance on forward-looking
statements. Such forward-looking statements are inherently uncertain, and actual
results may differ from expectations. the Company is not under any obligation,
and it expressly disclaims any obligation, to update or alter any
forward-looking statements, whether as a result of new information, future
events or otherwise.
