Careers at Fannie Mae


Fannie Mae provides a range of mortgage buying services with a view to becoming the most valued housing partner in the US and providing liquidity, access to credit, and affordability in all US housing markets at all times, while effectively managing and reducing risk to businesses, taxpayers and the housing finance system.

Business segments

Fannie Mae organises its operations into three business segments:

  • Single-Family Credit Guaranty, which works with lender customers to acquire single-family mortgage loans through lender swap transactions, prices and manages the credit risk on loans in the Company’s single-family guaranty book, and works to prevent foreclosures and reduce costs of defaulted single-family loans through home retention solutions and foreclosure alternatives;
  • Multifamily, which works with lender customers to securitise multifamily mortgage loans, prices and manages the credit risk on loans in the Company’s multifamily guaranty book, and works to prevent foreclosures and reduce costs of defaulted multifamily loans through foreclosure alternatives; and
  • Capital Markets, which purchases mortgage assets and invests in non-mortgage interest-earning assets, purchases loans from lenders and sells securities to dealers, and manages the interest rate risk on the Company’s portfolio by issuing debt securities in a wide range of maturities and by using derivatives.


Fannie Mae is a government-sponsored enterprise that was chartered by the US Congress in 1938. The Company was established in response to widespread mortgage debts across the country as a result of the Great Depression. Fannie Mae was originally chartered as the National Mortgage Association of Washington, with the explicit purpose of providing local banks with federal money to finance home mortgages in an attempt to raise levels of home ownership and the availability of affordable housing.

Fannie Mae was acquired in 1950 by the Housing and Home Finance Agency, and in 1954 the Federal National Mortgage Association Charter Act made Fannie Mae into a mixed ownership company, with the federal government holding the Company’s preferred stock and private investors holding its common stock. The Company has continued to develop and despite experiencing difficult periods, notably the recent US housing crisis, remains a key component of the US mortgage market.
