The Federal Home Loan Mortgage Corporation (FHLMC), commonly known as Freddie Mac, plays a crucial role in the United States' secondary housing finance market. It primarily acquires single-family and multi-family residential mortgage loans from a diverse network of originators, while also investing in various mortgage-backed securities and other related debt instruments. Its operations are structured into two main divisions: Single-family and Multifamily. The Single-family division is responsible for purchasing, pooling into securities, and guaranteeing individual home loans. It actively manages the credit risk associated with these mortgages, oversees a portfolio of mortgage-related investments, handles securitization processes, and performs treasury functions. This segment serves a broad array of financial institutions, including mortgage banks, commercial and regional banks, community banks, credit unions, housing finance authorities, savings institutions, and non-depository lenders. Conversely, the Multifamily division focuses on the acquisition, disposition, securitization, and backing of loans and securities related to multi-unit properties. This involves the creation and guarantee of specific products like multifamily K and SB certificates, as well as other securitization vehicles and credit risk transfer mechanisms. It also provides various other mortgage-related guarantees. Its diverse client base encompasses banks and other deposit-taking entities, insurance firms, asset managers, central banks, pension funds, state and local government bodies, real estate investment trusts (REITs), brokers, dealers, and a wide range of institutional lenders. Established in 1970, the company maintains its corporate headquarters in McLean, Virginia.
