Report of Independent Accountants

To the Board of Directors and Shareholder
of CIT Group Inc.

We have examined  mangement's  assertion  about The CIT  Group/Sales  Financing,
Inc.'s  (the  "Company's"),  a  wholly  owned  subsidiary  of  CIT  Group  Inc.,
compliance  with the minimum  servicing  standards  identified  in the  Mortgage
Bankers Association of America's Uniform Single Attestation Program for Mortgage
Bankers as of and for the year ended  December  31,  2001,  as  included  in the
accompanying management assertion (see Exhibit 1). 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 made 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 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, 2001, is fairly stated, in all material respects.
