The Federal Home Loan Mortgage Corporation plays a crucial role in the United States' secondary mortgage market. Its core business involves acquiring residential mortgage loans, encompassing both single-family and multi-family properties, directly from the financial institutions that originated them. Furthermore, the company strategically invests in a variety of mortgage loans and related financial instruments. The corporation organizes its operations into two distinct divisions: Single-family and Multifamily. The Single-family segment is tasked with purchasing, transforming into securities, and guaranteeing individual home loans. This division also manages the inherent credit risk associated with single-family mortgages, oversees its portfolio of mortgage investments, conducts securitization activities for single-family loans, and performs treasury functions. It provides services to a broad spectrum of financial entities, including mortgage banking companies, commercial and regional banks, community banks, credit unions, housing finance agencies, savings institutions, and non-depository financial institutions. Conversely, the Multifamily segment focuses on the acquisition, sale, securitization, and guarantee of loans and securities tied to multi-unit properties. These activities are facilitated through the issuance of specialized multifamily K and SB certificates, as well as other securitization products and various credit risk transfer mechanisms. This segment also offers additional mortgage-related guarantees. Its diverse clientele includes banks, other depository institutions, insurance companies, money managers, central banks, pension funds, state and local governments, real estate investment trusts, brokers and dealers, and a wide array of lenders. Established in 1970, the Federal Home Loan Mortgage Corporation maintains its headquarters in McLean, Virginia.
