Freddie Mac:

The mission of the Federal Home Loan Mortgage Corporation (Freddie Mac) is to provide liquidity, stability and affordability to the housing market.  Congress defined this mission in its 1970 charter.

Freddie Mac makes sure there's a stable supply of money for lenders to make the loans new homebuyers need.  This gives everyone better access to homefinancing, raising the roof on homeownership opportunity in America.  Financing housing for low and moderate income families has been a key part of Freddie Mac's business since it started.  Freddie Mac's vision is that families must be able both to afford to purchase a home and to keep that home.
