Ginnie Mae's mission is to promote the availability of affordable housing for low- and moderate-income individuals and families in the United States. This is achieved by enhancing the liquidity and stability of the housing finance market through the backing of mortgage-backed securities. By ensuring that investors can have confidence in these securities, Ginnie Mae plays a critical role in facilitating the flow of capital to mortgage lenders. This ultimately benefits homebuyers, as it helps lower borrowing costs and increases access to mortgage financing. Ginnie Mae also seeks to ensure that its programs are operated in a sustainable and efficient manner.
