AMENDMENT LETTER

    Re: Credit Agreement dated as of October 31, 2006 among NNN Apartments REIT
Holdings, L.P. (“Borrower”), Wachovia Bank, National Association, as Agent, and
the lenders from time to time a party thereto (the “Credit Agreement”)

Gentlemen:

Terms used herein but not otherwise defined herein shall have the meanings set
forth in the Credit Agreement. Pursuant to letter agreement dated March 20, 2007
(the “Existing Waiver Letter”), Borrower, Guarantor, the Agent and the Lenders
have agreed that the Lenders have no obligation to make additional Loans or
otherwise extend any credit to the Borrower under the Credit Agreement unless
otherwise agreed in writing by the Lenders in their sole and absolute
discretion. The Borrower has requested that the Lenders agree to the suspension
of the unused fee payable pursuant to Section 3.6(a) of the Credit Agreement
until such time as the Lenders have agreed in writing to make additional Loans.

Subject to the execution and delivery of this letter by Borrower, Guarantor,
Agent and the Lenders, and until such time as the Lenders have agreed to make
additional Loans to Borrower in accordance with the Existing Waiver Letter,
(a) the Lenders agree that the obligation of Borrower to pay the unused fee
pursuant to Section 3.6(a) of the Credit Agreement shall be suspended and (b)
the Lenders waive compliance with the covenants set forth in Section 9.1(a) (the
Debt to Total Asset Value Ratio), Section 9.1(b) (the Fixed Charge Coverage
Ratio) and Section 9.1(c) (the Implied Debt Service Coverage Ratio) of the
Credit Agreement (collectively, the “Financial Covenants”), together with the
related obligation of Borrower to report as to compliance with the Financial
Covenants. The Borrower acknowledges and agrees that the decision whether to
make any additional Loans is and shall be within the sole and absolute
discretion of the Lenders and subject to the approval of both Lenders’
respective credit committees. If and when the Lenders agree to make additional
Loans or otherwise extend any credit to the Borrower under the Credit Agreement
as provided herein, the Lenders hereby agree that, in recognition of the upfront
fees paid to Lenders on October 31, 2006, no upfront fee will be charged to the
Borrower in connection with making the Credit Agreement available to the
Borrower for additional extensions of credit, so long as the Revolving Loan
Termination Date has not been extended.

Except as hereinabove set forth, all terms, covenants and provisions of the
Credit Agreement and the other Loan Documents remain unaltered and in full force
and effect and the parties hereto do hereby expressly ratify and confirm the
Credit Agreement and the other Loan Documents. Other than as expressly set forth
herein, nothing in this letter shall be deemed or construed to constitute, and
there has not otherwise occurred, a novation, cancellation, satisfaction,
release, extinguishment, or substitution of the indebtedness evidenced by the
Notes or the other obligations of Borrower and Guarantor under the Loan
Documents.

This letter shall constitute a Loan Document. This letter may be executed in any
number of counterparts which shall together constitute but one and the same
agreement. This letter shall be governed by, and construed in accordance with,
the laws of the State of Georgia. This letter may be amended only in accordance
with the terms of the Credit Agreement.
