The Federal Home Loan Mortgage Corporation is a prominent entity within the United States' secondary mortgage market. Its core function involves acquiring residential mortgage loans, encompassing both single-family homes and multi-unit properties, from various originating lenders. The corporation further invests in mortgage loans and securities tied to mortgages. It is organized into two distinct operating segments: Single-family and Multifamily. The Single-family segment is dedicated to acquiring, securitizing, and guaranteeing mortgages on single-family residences. Additionally, this segment undertakes the management of credit risk for single-family mortgages, supervises its portfolio of related investments, and directs securitization and treasury operations. Its client base extends across numerous financial institutions, including mortgage banking companies, commercial and regional banks, community banks, credit unions, housing finance agencies, savings institutions, and non-depository financial firms. The Multifamily segment's activities involve the procurement, sale, securitization, and assurance of loans and securities associated with multi-unit residential developments. This is accomplished through the issuance of multifamily K and SB certificates, various other securitization products, and credit risk transfer mechanisms, alongside providing further mortgage-related guarantees. This segment serves a diverse group of stakeholders, including banks, other depository institutions, insurance companies, money managers, central banks, pension funds, state and local government bodies, real estate investment trusts, brokers, dealers, and a variety of lenders. Founded in 1970, the corporation maintains its headquarters in McLean, Virginia.
