Independent Accountants' Report


The Board of Directors
Wells Fargo Home Mortgage, a division of Wells Fargo Bank, N.A.:


We have examined management's assertion, included in the accompanying Assertion
of Management of Wells Fargo Home Mortgage, a division of Wells Fargo Bank, N.A.
(the Company), that the Company complied with the minimum servicing standards
set forth in the Mortgage Bankers Association of America's Uniform Single
Attestation Program for Mortgage Bankers (USAP) as of and for the year ended
December 31, 2005. 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 and,
accordingly, included examining, on a test basis, evidence about the Company's
compliance with the minimum servicing standards specified above 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 the 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.

RE: SASCO 2005-WF1
    Annual Officer's Certificate as to Compliance

Dear Ms. Shedrick:

The undersigned Officer certifies the following for the period ending on
December 31, 2005:

1. I have reviewed the activities and performance of the Master Servicer during
   the preceding calendar year under the terms of the Trust Agreements and to
   the best of this Officer's knowledge, the Master Servicer has fulfilled all
   of its duties, responsibilities or obligations under the Agreements;

2. Based on said review and to the best of this Officer's knowledge, the Master
   Servicer is not in default of its obligations under the terms of the Trust
   Agreements in any material respect, or, if there is a default in the
   fulfillment of its obligations, a description of each default or failure and
   the nature and status thereof has been reported to this Officer;

3. To the best of this Officer's knowledge, nothing has arose to lead this
   Officer to believe that its Servicer has failed to perform any of its duties,
   responsibilities and obligations under its Servicing Agreement during the
   preceding calendar year;

4. To the best of this Officer's knowledge, the Servicer is not in default of
   its obligations under the terms of its Servicing Agreement in any material
   respect, or, if there is a default in the fulfillment of its obligations, a
   description of each default or failure and the nature and status thereof has
   been reported to this Officer;

5. The Master Servicer has received from its Servicer such Servicer's annual
   certificate of compliance and a copy of such Servicer's annual audit report,
   in each case to the extent required under the applicable Servicing Agreement,
   or, if any such certificate or report has not been received by the Master
   Servicer, the Master Servicer is using its best reasonable efforts to obtain
   such certificate or report.
