This bill establishes an Affordable Housing Guaranteed Loan Program within the New Hampshire Housing Finance Authority, aimed at promoting affordable housing for low- and moderate-income individuals. The program defines "affordable housing" as housing costs that do not exceed 30% of the gross income of eligible persons, and it includes various types of housing such as manufactured housing parks and homes for persons with disabilities. The bill outlines the definitions of low, moderate, and very low-income individuals, and it mandates the authority to adopt rules regarding the program's administration, including the selection of eligible lenders and the types of activities eligible for financing.

The bill also stipulates that the authority may issue a guarantee equal to 80% of the principal due on loans, with a cap of $30 million per lender per fiscal year and an aggregate limit of $300 million. The full faith and credit of the state is pledged to support these guarantees, and the state treasurer is authorized to advance funds to the authority as needed. Notably, the program is set to be repealed on July 1, 2030, and the bill does not provide funding or authorize new positions, with potential costs to the state remaining indeterminable based on loan defaults.
