42 U.S. Code § 12852 - Assistance for first-time homebuyers
Assistance payments so that the rate of interest payable on the mortgages by the homebuyers does not exceed 6 percent.
Assistance payments to provide amounts for downpayments (including closing costs and other costs payable at the time of closing) on mortgages for such homebuyers.
Interest rate buydowns and downpayment assistance in the manner provided in subsection (e) of this section.
Assistance payments to provide loans (secured by second mortgages) with deferred payment of interest and principal; and 
Grants to public organizations or agencies to establish revolving loan funds to provide homeownership assistance to eligible first-time homebuyers consistent with the requirements of this subchapter. Such grants shall be matched by an equal amount of local investment in such revolving loan funds. Any proceeds or repayments from loans made under this paragraph shall be returned to the revolving loan fund established under this paragraph to be used for purposes related to this section.
The homebuyer (and spouse, where applicable) shall certify that the homebuyer has made a good faith effort to obtain a market rate mortgage and has been denied because the annual income of the homebuyer and the members of the family of the homebuyer residing with the homebuyer is insufficient.
The property securing the mortgage is a single-family residence or unit in a cooperative and is the principal residence of the homebuyer.
The principal obligation of the mortgage does not exceed the principal amount that could be insured with respect to the property under the National Housing Act [12 U.S.C. 1701 et seq.].
The interest payable on the mortgage is established at a fixed rate that does not exceed a maximum rate of interest established by the Trust taking into consideration prevailing interest rates on similar mortgages.
The mortgage has been made to, and is held by, a mortgagee that is federally insured or that is otherwise approved by the Trust as responsible and able to service the mortgage properly.
For a first-time homebuyer to receive downpayment assistance under subsection (a)(2) of this section, the homebuyer shall have paid not less than 1 percent of the cost of acquisition of the property (excluding any mortgage insurance premium paid at the time the mortgage is insured), as such cost is estimated by the Board of Directors.
Assistance payments under this subchapter shall be secured by a lien on the property involved. The lien shall be subordinate to all mortgages existing on the property on the date on which the first assistance payment is made.
Assistance payments under this subchapter shall be repayable from the net proceeds of the sale, without interest, upon the sale of the property for which the assistance payments are made. If the sale results in no net proceeds or the net proceeds are insufficient to repay the amount of the assistance payments in full, the Board of Directors shall release the lien to the extent that the debt secured by the lien remains unpaid.
If the aggregate annual income of the homebuyer (and family of the homebuyer) assisted under this subchapter exceeds the applicable maximum income allowable under subsection (b)(2) of this section for any 2-year period after such assistance is provided, the Board of Directors may provide for the repayment, on a monthly basis, of all or a portion of such assistance payments, based on the amount of assistance provided and the income of the homebuyer (and family of the homebuyer).
If the property for which assistance payments are made ceases to be the principal residence of the first-time homebuyer (or the family of the homebuyer), the Board of Directors may provide for the repayment of all or a portion of the assistance payments.
Amounts available in any fiscal year for assistance under this subchapter shall be allocated for homebuyers in each State on the basis of the need of eligible first-time homebuyers in each State for such assistance in comparison with the need of eligible first-time homebuyers for such assistance among all States.
The Trust shall provide assistance for first-time homebuyers in the form of interest rate buydowns and downpayment assistance under this subsection. Such assistance shall be available only with respect to mortgages for the purchase of residences (A) financed with the proceeds of a qualified mortgage bond (as such term is defined in section 143 of title 26), or (B) for which a credit is allowable under section 25 of title 26.
The Trust may make assistance payments under subparagraphs (A) and (B) of paragraph (3) with respect to a single mortgage of a homebuyer.
