Federal Home Loan Mortgage Corporation, commonly known as Freddie Mac, plays a significant role in the secondary mortgage market within the United States. Its core business involves acquiring residential mortgage loans, encompassing both single-family homes and multi-unit properties, from various originating lenders. The corporation also strategically invests in mortgage-backed assets and directly in mortgage debt. Its operations are segmented into two distinct divisions: 1. Single-family: This segment is responsible for purchasing, pooling into securities, and guaranteeing mortgages on individual residences. It actively manages the credit risk associated with these single-family loans, oversees its portfolio of related investments, handles the securitization processes for these housing types, and performs essential treasury functions. This division serves a broad clientele, including mortgage banking firms, commercial and regional banks, community banks, credit unions, housing finance agencies, savings institutions, and other non-depository financial entities. 2. Multifamily: Dedicated to multi-unit properties, this segment buys, sells, securitizes, and guarantees loans and related securities. This often involves issuing specialized certificates such as multifamily K and SB products. Furthermore, it originates and backs other securitized instruments, various credit risk transfer products, and provides additional mortgage-related guarantees. Its diverse client base includes banks, other depository institutions, insurance companies, asset managers, central banks, pension funds, state and local government bodies, real estate investment trusts, brokers and dealers, and a wide array of lenders. Founded in 1970, the company's main office is situated in McLean, Virginia.
