ITEM 4.01 CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT

On August 5, 2005, the Audit Committee of the Board of Directors of Flagstar
Bancorp, Inc. (the "Company") engaged Virchow, Krause & Company, LLP ("Virchow
Krause") as the Company's independent registered public accounting firm
commencing immediately. As part of its engagement, Virchow Krause will review
the financial statements contained in the Company's Form 10-Qs filed during the
remainder of 2005 (including the Form 10-Q for the quarter ended June 30, 2005)
and audit the Company's financial statements for the year ending December 31,
2005. The Company's prior independent registered public accounting firm, Grant
Thornton LLP, resigned on June 13, 2005.

During the two most recent fiscal years and through August 5, 2005, the Company
did not consult Virchow Krause with respect to (i) the application of
accounting principles to any transaction, either contemplated or proposed, (ii)
the type of audit opinion that might be rendered on the Company's financial
statements, or any matter that was either the subject of a disagreement (as
defined in Item 304(a)(1)(iv) of Regulation S-K) or a reportable event (as
described in Item 304(a)(1)(v) of Regulation S-K). Attached and incorporated
herein by reference as Exhibit 99.1 is a copy of the press release issued by the
Company on August 5, 2005 announcing the engagement of Virchow Krause.
