(a) Rents. The DHHL must develop and follow written policies governing rents for rental housing units assisted with NHHBG funds, including methods by which rents are determined. The maximum monthly rent for a low-income family may not exceed 30 percent of the family's monthly adjusted income.

(b) Lease-purchase. If DHHL assists low-income families to become homeowners of rental housing through a long-term lease (i.e. 10 or more years) with an option to purchase the housing, DHHL must develop and follow written policies governing lease-purchase payments for rental housing units assisted with NHHBG funds, including methods by which payments are determined. The maximum monthly payment for a low-income family may not exceed 30 percent of the family's monthly adjusted income.

(c) Exception for certain homeownership payments. Homeownership payments for families who are not low-income, as permitted under § 1006.301(b), are not subject to the requirement that homebuyer payments may not exceed 30 percent of the monthly adjusted income of that family.

(d) Low-income families who receive homeownership assistance other than lease-purchase assistance are not subject to the limitations in paragraphs (a) and (b) of this section.
