Federal National Mortgage Association Fannie Mae

Fannie Mae is a government-sponsored, stockholder-owned mortgage finance company chartered to support liquidity and stability in the U.S. housing market. It does not originate mortgages directly; instead, it buys or guarantees residential and multifamily mortgage loans, securitizes them into mortgage-backed securities, and provides credit guarantees to investors.
