        `charitable purposes' includes the provision of qualified 
        homeowner downpayment assistance.

        providing any downpayment for the acquisition of any property 
        as a principal residence (within the meaning of section 121) 
        for a qualified taxpayer if--
                    ``(A) with respect to such property, such gift does 
                not exceed 20 percent of 110 percent of the maximum 
                principal obligation allowable, and
                    ``(B) the purchase price of such property does not 
                exceed 110 percent of the maximum principal obligation 
                allowable.
            ``(3) Maximum principal obligation allowable.--The maximum 
        principal obligation allowable with respect to any property is 
        the maximum principal obligation allowable for the area in 
        which such property is located, determined under section 
        203(b)(2)(A) of the National Housing Act, for a loan insured

        downpayment assistance if the contribution is made directly or 
        indirectly in connection with a transaction in which the 
        purchaser of a home received downpayment assistance and the 
        contributor--
                    ``(A) received the downpayment assistance,
