How It Works
Ginnie Mae is an agency of the United States Department of Housing and Urban Development. Congress established Ginnie Mae in 1968. It is also known by the acronym GNMA.
When a GNMA-approved bank makes several mortgages, it may sell the pool of mortgages to a bond dealer. The dealer in turn sells securities backed by the underlying mortgages (hence the name "mortgage-backed securities"). Ginnie Mae guarantees the timely payment of interest and principal on these mortgage-backed securities. It is important to note that Ginnie Mae does not buy or sell mortgages nor does it issue the mortgage-backed securities it guarantees.
In general, Ginnie Mae only guarantees mortgage-backed securities that have underlying mortgages insured by the Federal Housing Administration (FHA), the Department of Veterans Affairs (VA), the Rural Housing Service (RHS), or the Office of Public and Indian Housing (PIH).
Here's how it works: The original lenders forward monthly payments received from homeowners to an agent, who passes the payments on to the security holders. A portion of the interest payments is retained by Ginnie Mae as a guarantee fee, and a portion is retained by the original lenders as a servicing fee. If a homeowner defaults on a loan underlying a Ginnie Mae security, Ginnie Mae makes the payments on the mortgage-backed securities until the underlying property is foreclosed.
