      Single-Family Green MBS
Single-Family Green Mortgage-Backed Securities (MBS) are another demonstration of Fannie Mae's commitment to leading and innovating in green finance.

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.

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

In 2023, Fannie Mae began allowing Solar PV loans into the Single-Family Green MBS program. To be eligible for consideration, Solar PV loans must have systems that produce a minimum of a 20% reduction of the home's electricity consumption on an annual basis.

Fannie Mae independently validates the green building certification, Home Energy Score (HES) report, and eligibility percentage of all properties underlying the MBS through a proprietary database.
