                       Registration Statement on Form SF-3
                       Filed July 30, 2021
                       File No. 333-258342

      Dear Mr. Singh:

             We have limited our review of your registration statement to those
issues we have
      addressed in our comment. In our comment, we may ask you to provide us
with information so
      we may better understand your disclosure.

             Please respond to this letter by amending your registration
statement and providing the
      requested information. If you do not believe our comment applies to your
facts and
      circumstances or do not believe an amendment is appropriate, please tell
us why in your
      response.

             After reviewing any amendment to your registration statement and
the information you
      provide in response to this comment, we may have additional comments.

      General

          1. We note your registration statement contemplates asset pools with
loans secured by
             residential cooperative properties. We note that these loans have
been tied to floating
             rates, most often linked to LIBOR. We also note that shareholders
of the residential
             cooperatives purchase shares or stock that entitle the shareholder
to proprietary leases or
             occupancy agreements which confer exclusive rights to occupy
specific units, the value
             of which depends on the appraisal of the property rather than
expected rental income.
             Because the primary source of repayment on the loan will not be:
(i) the proceeds of the
             sale, refinancing, or permanent financing of the property; or (ii)
rental income associated
             with the property, the loans secured by the residential
cooperatives are not commercial
             mortgages. See definition of commercial real estate loan in Rule
14 of Regulation RR
             (17 CFR 246.14). Please remove the loans backed by residential
cooperative properties
