Federal Home Loan Mortgage Corporation (FMCCO) plays a crucial role in the secondary mortgage market across the United States. Its primary function involves acquiring residential mortgage loans, covering both single-family homes and multi-unit properties, which are initially issued by various lending institutions. Additionally, the company makes investments in existing mortgage loans and securities tied to mortgages. The organization structures its activities through two distinct divisions: Single-family and Multifamily. The Single-family division is tasked with the procurement, packaging into securities, and guarantee of mortgage loans for individual residences. This segment also actively manages the credit risk associated with single-family mortgages, oversees its portfolio of mortgage-related investments, directs securitization processes for single-family loans, and performs treasury functions. Its services are extended to a diverse array of financial entities, such as mortgage banking firms, commercial and regional banks, community banks, credit unions, housing finance agencies, savings institutions, and non-depository financial institutions. In contrast, the Multifamily division focuses on the acquisition, divestiture, securitization, and backing of loans and financial instruments related to multi-unit properties. This includes the issuance of specific multifamily K and SB certificates, along with other products designed for securitization, credit risk transfer, and various forms of mortgage-related guarantees. The Multifamily segment serves a broad client base, including banks and other depository institutions, insurance companies, money managers, central banks, pension funds, state and local government entities, real estate investment trusts, brokers and dealers, and a wide range of lenders. The corporation commenced operations in 1970 and is presently headquartered in McLean, Virginia.
