Dear William R. Jacobs:

       We have limited our review of your filing to the financial statements 
and related
disclosures and have the following comments.

       Please respond to this letter within ten business days by providing the 
requested
information or advise us as soon as possible when you will respond. If you do 
not believe a

       After reviewing your response to this letter, we may have additional

Form 10-K for the Fiscal Year Ended December 31, 2023
Item 1. Business
Lending Activities, page 4

1.     We note your disclosure that your principal lending activity is the 
origination of
       multifamily real estate loans and, to a lesser extent, other commercial 
real estate loans
       and that these loans comprise approximately 65% and 22%, respectively, 
of your total
       loan portfolio as of December 31, 2023. Given the significance of these 
loans in your total
       loan portfolio, please revise your disclosure, in future filings, to 
further disaggregate the
       composition of these loans into owner occupied and non-owner occupied 
and other
       characteristics (e.g., current weighted average and/or range of 
loan-to-value ratios,
       occupancy rates, etc.) by loan category which would be material to an 
investor   s
       understanding of these loans.

conditions. Please revise
       your disclosures, in future filings, to further expand on the details of 
the risk management
       processes that have been implemented, including any specific details of 
underwriting or
       other policy changes, actions taken and frequency of assessments 
performed by

in future filings,
       the related disclosure in the first Risk Factor on page 31 as 
appropriate, for example to
       address any    additional policies or procedures    that have been or 
are expected to be
       adopted.
