The Federal Housing Administration (FHA) offers an Energy Mortgage Program to help homebuyers and homeowners finance the cost of adding energy efficiency features to a new or existing house as part of a refinancing mortgage. The mortgage loan is funded by a separate lending institution, but is insured by the U.S. Dept. of Housing and Urban Development as well as the Federal Housing Administration. This encourages lenders to make credit available to borrowers who would not otherwise qualify for conventional loans on affordable terms. The cost of the energy improvements and estimate of the energy savings must be determined by a home energy rating system (HERS) or an energy consultant. In order to qualify, applicants must meet standard FHA credit qualifications. The borrower must be able to finance an upfront, as well as annual, premium. The property must be between 1 and 4 units.
