METHODOLOGY:
This bill requires the New Hampshire Housing Finance Authority (NHHFA) to offer loan guarantees to approved lenders for financing accessory dwelling units (ADUs). These guarantees would cover between 80% and 100% of the loan amount based on the appraised value of the completed ADU. The total amount of guarantees issued each year would be capped at $100 million. Additionally, this bill provides a $25,000 appropriation in fiscal year 2027 and $25,000 in fiscal year 2028 to the Housing Finance Authority for the purpose of offsetting the administrative costs.
The NHHFA anticipates annual administrative and staffing costs of approximately $25,000, which would initially be covered by General Funds. However, NHHFA is expected to offset these costs over time by charging lenders a small monthly fee.
