                      ------------------------------------

This free writing prospectus does not contain all information that is required
to be included in a prospectus required to be filed as part of a registration
statement. This free writing prospectus is not an offer to sell or a
solicitation of an offer to buy these securities in any state where such offer,
solicitation or sale is not permitted.

The information in this free writing prospectus, if conveyed prior to the time
of your contractual commitment to purchase any of the Certificates, supersedes
any conflicting information contained in any prior similar materials relating to
the Certificates. The information in this free writing prospectus may be amended
or supplemented. This free writing prospectus is being delivered to you solely
to provide you with information about the offering of the Certificates referred
to in this free writing prospectus and to solicit an offer to purchase the
Certificates, when, as and if issued. Any such offer to purchase made by you
will not constitute a contractual commitment by you to purchase or give rise to
an obligation by the underwriters to sell any of the Certificates, until the
underwriters have accepted your offer to purchase Certificates; any "indications
of interest" expressed by you, and any "soft circles" generated by us, will not
create binding contractual obligations for you or us.

You are advised that the terms of the Certificates, and the characteristics of
the mortgage loan pool backing them, may change (due, among other things, to the
possibility that mortgage loans that comprise the pool may become delinquent or
defaulted or may be removed or replaced and that similar or different mortgage
loans may be added to the pool, and that one or more classes of Certificates may
be split, combined or eliminated), at any time prior to the time sales to
purchasers of the Certificates will first be made. You are advised that
Certificates may not be issued that have the characteristics described in these
materials. The underwriter's obligation to sell such Certificates to you is
conditioned on the mortgage loans and Certificates having the characteristics
described in these materials. If a material change does occur with respect to
such Certificates, our contract will terminate, by its terms, without any
further obligation or liability between us (an "Automatic Termination"). If an
Automatic Termination does occur, the underwriter will notify you, and neither
the issuer nor any underwriter will have any obligation to you to deliver all or
any portion of the Certificates which you have committed to purchase, and none
of the issuer nor any underwriter will be liable for any costs or damages
whatsoever arising from or related to such non-delivery.

This free writing prospectus was prepared on the basis of certain assumptions
(including, in certain cases, assumptions specified by the recipient hereof)
regarding the pool assets and structure, including payments, interest rates,
weighted average lives and weighted average loan age, loss, spreads, market
availability and other matters. The actual amount, rate or timing of payments on
any of the underlying assets may be different, and sometimes materially
different than anticipated, and therefore the pricing, payment or yield
information regarding the Certificates may be different from the information
provided herein. There can be no assurance that actual pricing will be completed
at the indicated value(s). In addition, pricing of the Certificates may vary
significantly from the information contained in this free writing prospectus as
a result of various factors, including, without limitation, prevailing credit
spreads, market positioning, financing costs, hedging costs and risk and use of
capital and profit. The pricing estimates contained herein may vary during the
course of any particular day and from day to day. You should consult with your
own accounting or other advisors as to the adequacy of the information in this
free writing prospectus for your purposes.

Wachovia Commercial Mortgage Securities, Inc. (the "Depositor") has filed a
registration statement (including a prospectus) (SEC File no. 333-131262) with
the SEC for the new offering to which this free writing prospectus relates.
Before you invest, you should read the prospectus in that registration statement
and other documents the Depositor has filed with the SEC for more complete
information about the Depositor, the issuing entity, and this offering. You may
get these documents for free by visiting EDGAR on the SEC Web site at
www.sec.gov. Alternatively, the Depositor, any underwriter, or any dealer
participating in the offering will arrange to send you the prospectus if you
request it by calling 1-800-745-2063.

This free writing prospectus does not contain all information that is required
to be included in a prospectus required to be filed as part of a registration
statement. This free writing prospectus is not an offer to sell or a
solicitation of an offer to buy these securities in any state where such offer,
solicitation or sale is not permitted.

The information in this free writing prospectus, if conveyed prior to the time
of your contractual commitment to purchase any of the Certificates, supersedes
any conflicting information contained in any prior similar materials relating to
the Certificates. The information in this free writing prospectus may be amended
or supplemented. This free writing prospectus is being delivered to you solely
to provide you with information about the offering of the Certificates referred
to in this free writing prospectus and to solicit an offer to purchase the
Certificates, when, as and if issued. Any such offer to purchase made by you
will not constitute a contractual commitment by you to purchase or give rise to
an obligation by the underwriters to sell any of the Certificates, until the
underwriters have accepted your offer to purchase Certificates; any "indications
of interest" expressed by you, and any "soft circles" generated by us, will not
create binding contractual obligations for you or us.

You are advised that the terms of the Certificates, and the characteristics of
the mortgage loan pool backing them, may change (due, among other things, to the
possibility that mortgage loans that comprise the pool may become delinquent or
defaulted or may be removed or replaced and that similar or different mortgage
loans may be added to the pool, and that one or more classes of Certificates may
be split, combined or eliminated), at any time prior to the time sales to
purchasers of the Certificates will first be made. You are advised that
Certificates may not be issued that have the characteristics described in these
materials. The underwriter's obligation to sell such Certificates to you is
conditioned on the mortgage loans and Certificates having the characteristics
described in these materials. If a material change does occur with respect to
such Certificates, our contract will terminate, by its terms, without any
further obligation or liability between us (an "Automatic Termination"). If an
Automatic Termination does occur, the underwriter will notify you, and neither
the issuer nor any underwriter will have any obligation to you to deliver all or
any portion of the Certificates which you have committed to purchase, and none
of the issuer nor any underwriter will be liable for any costs or damages
whatsoever arising from or related to such non-delivery.

This free writing prospectus was prepared on the basis of certain assumptions
(including, in certain cases, assumptions specified by the recipient hereof)
regarding the pool assets and structure, including payments, interest rates,
weighted average lives and weighted average loan age, loss, spreads, market
availability and other matters. The actual amount, rate or timing of payments on
any of the underlying assets may be different, and sometimes materially
different than anticipated, and therefore the pricing, payment or yield
information regarding the Certificates may be different from the information
provided herein. There can be no assurance that actual pricing will be completed
at the indicated value(s). In addition, pricing of the Certificates may vary
significantly from the information contained in this free writing prospectus as
a result of various factors, including, without limitation, prevailing credit
spreads, market positioning, financing costs, hedging costs and risk and use of
capital and profit. The pricing estimates contained herein may vary during the
course of any particular day and from day to day. You should consult with your
own accounting or other advisors as to the adequacy of the information in this
free writing prospectus for your purposes.
