Exhibit (a)(3)










August 16, 2006

TO:                  UNIT HOLDERS OF SECURED INCOME, LP

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 all Units of limited
partnership interest (the "Units") in SECURED INCOME, LP (the "Partnership") at
a purchase price equal to:

                                   $7 per Unit
                                   -----------

You may wish to consider the following reasons for selling your Units in the
Partnership:

o    UNCERTAINTY OF PARTNERSHIP TERMINATION. The general partner is in
     negotiations to sell the Partnership's remaining property, but it already
     fell out of contract once at a higher price. Thus, there can be no
     assurance that the sale will occur in the near future or at all.

o    REDUCTION OF PHANTOM INCOME FOR 2006. You will not receive sufficient
     distributions to offset the taxable income you must report on your tax
     return. The Partnership has stated that each Unit will be allocated $58 in
     income from the sale of the Westmont property, but the Partnership only
     paid approximately $38 to $42.10 per Unit, depending upon withholding
     taxes. The difference of up to $20 per Unit is phantom income. If you sell
     to us, you will be able to offset this allocation of income with your basis
     in the Units, which was $20 per Unit for original investors when they
     purchased Units. Your basis would change based upon your individual
     circumstances, so you should check with your tax adviser.

o    NO FURTHER WITHHOLDING TAXES FOR NON-RESIDENTS. If you sell your Units to
     us, you will receive the entire $7 per Unit, less any distributions (and
     none expected). Limited partners who were not residents of New York had
     approximately $4 per Unit of the recent distribution withheld for New York
     state taxes. If and when the Fieldpoint property sells, the Partnership
     will be required to withhold taxes from non-residents of Maryland, reducing
     the net amount of any potential distribution.

o    NO FUTURE IRS FILING REQUIREMENTS / ELIMINATION OF RETIREMENT ACCOUNT FEES.
     If you sell your Units to us this year, the 2006 tax year will be the final
     year for which you will be obligated to file a K-1 for the Partnership with
     your tax return and for which you incur fees for having this investment in
     your IRA or retirement account. This may represent a reduction in costs
     associated with filing complicated tax returns and fees charged by some
     custodians for holding this type of asset. Your decision to sell may have
     other favorable or unfavorable tax consequences and potential sellers
     should consult their individual tax advisers.

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 pink 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

This Offer expires (unless extended) September 18, 2006.
