About Us

What We Do

We are a leading source of financing for mortgages in the United States. We serve the people who house America. Together with our partners, we make sure that homeowners, homebuyers, and renters across the country have access to affordable financing opportunities.

Fannie Mae aspires to be America's most valued housing partner. We provide our customers with products and tools they need to enable mortgage lending in the 21st century. We provide technology and risk tools to help our customers advance their businesses. We listen to and support our customers to make the mortgage process more efficient and effective.

We continually work to improve the way we operate because we want to make the housing finance system safer and more effective for our company, our customers, homeowners, homebuyers, renters, and for America.

We have two primary lines of business:


Our Single-Family business helps lenders originate mortgages in a safe and sound manner. Our funding makes products such as the 30-year, fixed-rate mortgage possible. It provides homeowners with stable, predictable mortgage payments over the life of the loan and remains the most popular choice among homebuyers.

We provide lenders with a variety of financing solutions so they can support a diverse group of homebuyers and homeowners in all markets and during all economic cycles. We enable our lender customers to originate and tailor mortgage loans to meet the needs of today's borrower.

At the same time, we establish and uphold responsible lending standards. We’ve put in place strong underwriting, eligibility, and risk management standards to help protect taxpayers.

We provide liquidity to the single-family market by purchasing and guaranteeing mortgage loans that are made by our lender customers and issuing debt securities that attract global investors to finance U.S. housing. In recent years, we have become a company that distributes some of our mortgage credit risk to private investors and, as a result, we are reducing taxpayer risk.

Taken together, we are enabling our customers to extend credit to borrowers across the U.S., helping them to buy, refinance, and rent homes.

Fannie Mae is a market leader in financing for multifamily properties. Our Multifamily business works to ensure that access to affordable and workforce rental housing is available in all markets across the country.

In our Delegated Underwriting and Servicing (DUS?) program, we work with a national network of participating lender customers to finance apartment buildings. What's DUS? It is the cornerstone of the company's multifamily business. Through DUS, lenders share in the risk of the loans they sell to Fannie Mae. DUS is a unique model that leverages private capital to finance multifamily housing in communities throughout America.

We provide liquidity to the multifamily market by transforming multifamily loans into mortgage-backed securities. This increases available funds in the financial system, and helps ensure that there are funds available to finance workforce rental housing.
