Exhibit 99.2

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Morgan Stanley Credit Corporation
Riverwoods, Illinois

We have examined management’s assertion that Morgan Stanley Credit Corporation (the “Company”) has complied as of and for the year ended December 31, 2005, with its established minimum servicing standards described in the accompanying Management’s Assertion dated March 7, 2006 for the consumer loans sold to RWT Holdings, Inc. Management is responsible for the Company’s compliance with those minimum servicing standards. Our responsibility is to express an opinion on management’s assertion about the Company’s compliance based on our examination.

Our examination was conducted in accordance with attestation standards established by the American Institute of Certified Public Accountants, as adopted by the Public Accounting Oversight Board and, accordingly, included examining, on a test basis, evidence about the Company’s compliance with its minimum servicing standards and performing such other procedures as we considered necessary in the circumstances. We believe that our examination provides a reasonable basis for our opinion. Our examination does not provide a legal determination on the Company’s compliance with its minimum servicing standards.

In our opinion, management’s assertion that the Company complied with the aforementioned minimum servicing standards as of and for the year ended December 31, 2005, is fairly stated, in all material respects, based on the criteria set forth in Appendix A.
