Exhibit (a)(3)






February 16, 2007



TO:        UNIT HOLDERS OF 250 WEST 57TH ST. ASSOCIATES L.L.C.

SUBJECT:   OFFER TO PURCHASE UNITS

Dear Unit Holder:

As described in the enclosed Offer to Purchase and related Letters of
Transmittal (the "Offer") the Purchasers named in the attached Offer
(collectively the "Purchasers") are offering to purchase up to 140 Participation
Units of LLC Member interests (the "Units") in 250 WEST 57TH ST. ASSOCIATES
L.L.C. (the "Company") at a purchase price equal to:

                                $20,000 per Unit
                                ----------------

The Offer will provide you with an opportunity to liquidate all, or a portion
of, your investment in 250 WEST 57TH ST. ASSOCIATES L.L.C. without the usual
transaction costs associated with market sales or transfer fees. Reasons you may
wish to sell your Units include:

     o    UNCERTAINTY  OF COMPANY  TERMINATION.  Our offer provides you with the
          opportunity  to receive a  guaranteed  amount of money in a  specified
          time period.  The Supervisor has given no indication  when the Company
          will be  liquidating.  Therefore,  investors may not see liquidity for
          some time.

     o    ILLIQUIDITY OF UNITS. The relative  illiquidity of the Units resulting
          from the absence of a formal trading market makes the Units  difficult
          to sell.

     o    NO FUTURE IRS FILING REQUIREMENTS. The tax year in which you sell your
          Units will be the final year for which you will be obligated to file a
          K-1 for the  Company  with  your  tax  return.  This may  represent  a
          reduction in costs  associated  with filing  complicated  tax returns.
          Your  decision to sell may have other  favorable  or  unfavorable  tax
          consequences and potential sellers should consult their individual tax
          advisers.

     o    ELIMINATION  OF RETIREMENT  ACCOUNT FEES. If you sell your Units,  you
          may avoid  incurring  fees for having this  investment  in your IRA or
          retirement account. Because many custodians have transfer restrictions
          against LLC units or charge  additional  fees for holding this type of
          asset,  many  investors are faced with the task of searching for a way
          to avoid these fees.  Once our cash  payment is sent  directly to your
          retirement  account,  you are  free  to  consolidate  your  retirement
          accounts or transfer the funds to a custodian that offers lower fees.


After carefully reading the enclosed Offer, if you elect to tender your Units,
mail (using the enclosed pre-addressed, postage paid envelope) or fax (then
mail) a duly completed and executed copy of the Letter of Transmittal (printed
on purple paper) and change of address forms, and any other documents required
by the Letter of Transmittal, to the Depositary for the Offer at:

                         MacKenzie Patterson Fuller, LP
                               1640 School Street
                            Moraga, California 94556
                            Facsimile: (925) 631-9119
