UPDATE 1-American Home Mortgage falls on facility rumor

(Adds analyst comment, New York Stock Exchange request)

NEW YORK, July 19 (Reuters) - American Home Mortgage Investment Corp. AHM.N shares fell more than 20 percent Thursday on a rumor that a Wall Street investment firm had withdrawn a credit facility, analysts said.

But analysts who had spoken with the company's chief financial officer said the company denied the rumor.

The Melville, New York-based real estate investment trust, which makes home loans, did not immediately return a call seeking comment.

The company also did not comment to the New York Stock Exchange. In a statement on its Web site, the NYSE said it had requested American Home Mortgage issue a statement indicating whether there were any corporate developments that might explain the share price move.

Steven DeLaney, a managing director at JMP Securities in Atlanta, who spoke with the real estate investment trust's chief financial officer, said American Home assured him the rumor was false.

"The company had assured us that no credit facility has been pulled," DeLaney said.

Bose George, an analyst at Keefe, Bruyette & Woods in New York, said the company's CFO also assured him the rumors were false.

"He denied it pretty flatly, and said there is no liquidity issue," George said.
