This bill establishes an Affordable Housing Guaranteed Loan Program under 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, including 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 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 allows the authority to issue loan guarantees 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. It also pledges the full faith and credit of the state to support these guarantees, with the state treasurer authorized to advance funds as needed. The program is set to be repealed in 2030, and the bill does not provide funding or authorize new positions, with potential costs to the state remaining indeterminable based on loan defaults. The authority is expected to charge fees to lenders to offset administrative costs, which are projected to be modest.
