Single-Family Green MBS

Fannie Mae issues Single-Family Green MBS, which include either purchase money or refinance mortgage loans backed by newly constructed single-family residential homes receiving approved green building certifications within the last five years and/or meeting the performance eligibility target for solar photovoltaic (PV) systems as a source of energy generation and/or an eligible water certification with at least a 30% reduction in water usage in water-stressed or water-scarce areas.

Eligible Properties

Green Building Certification Loans

The ENERGY STAR^® Certification for New Homes (Residential) is a designation accepted by Fannie Mae as a baseline for loans underlying its Single-Family Green MBS because the certification is recognized for its:

• Nationally and globally distinguished standard for energy efficiency;
• Achievement of at least 10% more efficiency than homes built to code and a 20% improvement on average; and,
• Independent verification by trained and certified Home Energy Rating Companies.

We annually assess eligible green building certifications to ensure they meet the program guidelines and determine if new certifications should be added.

Solar Loans

Properties with solar PV systems may also be included in our program. To be eligible for consideration, the solar PV systems must produce a minimum of a 20% reduction of the home's electricity consumption on an annual basis.

Water Efficiency Loans

Properties located in water-stressed or water-scarce areas may also be included in our program. To be eligible for consideration, loans must have an eligible water certification and must achieve a water use reduction of at least 30% at the time construction or retrofits are completed, or within five years from the date Fannie Mae purchased the loan.

Fannie Mae independently validates the green building and water certifications, as well as the solar eligibility percentage of all properties underlying the MBS through a proprietary database.
