Learn about our business

Fannie Mae is a leading source of mortgage financing for single-family and multifamily mortgage lenders in the United States.  Our Charter is an Act of the U.S. Congress, which enshrines in law our purpose to provide liquidity and stability to America’s housing market and to promote access to affordable mortgage credit in communities throughout the country. Our work helps lenders offer affordable mortgage loans, like the 30-year, fixed-rate mortgage, to low- to moderate-income homebuyers and homeowners, and promotes access to safe, quality housing for renters. In 2020, we provided $1.4 trillion in liquidity to the U.S. mortgage market, roughly 7% of the U.S. GDP*. This enabled financing of approximately 6 million home purchases, refinancings, or rental units.

Since September 6, 2008, Fannie Mae has been under the conservatorship of the Federal Housing Finance Agency, which provides supervision, regulation, and housing mission oversight. More information can be found in our 2020 Form 10-K.

*US nominal GDP in 2020 is estimated at $20.936T based on U.S. Bureau of Economic Analysis data

We do not originate loans or lend money directly to homebuyers or multifamily property owners. The lenders we work with originate mortgage loans to qualified borrowers and sell loans that meet our standards to us so they have capital to continue lending to more borrowers. Fannie Mae securitizes the loans we purchase into mortgage-backed securities (MBS), which are sold to investors around the world. Our MBS investors know they will receive timely payment of principal and interest, because of our guarantee. We earn guaranty fees for assuming the credit risk on loans underlying our MBS.
