Single-Family Green MBS
New Green MBS Delivery and Pooling Options
Lenders can now deliver both whole loan and MBS pools and take advantage of a new Fannie Mae Green Majors® pool option.
Our Single-Family Green mortgage-backed securities (MBS) demonstrate our commitment to leading and innovating in mortgage loan financing for energy and water efficient homes. We support housing efficiency and resiliency to help homeowners reduce energy and water costs while improving home durability.
Our Single-Family Green MBS can be purchase money or refinance mortgage loans backed by newly constructed single-family residential homes that have received approved green building certifications within the last five years.
Emphasizing green building and sustainability supports one of our core values, ‘We grow for good.’
