Freddie Mac is a government-sponsored enterprise (GSE) created to enhance the liquidity, stability, and affordability of the U.S. housing market. Its primary function is to purchase mortgages from lenders, bundle them into mortgage-backed securities (MBS), and sell them to investors. This process provides lenders with capital to offer new mortgage loans, thus facilitating housing affordability and access. Freddie Mac, officially known as the Federal Home Loan Mortgage Corporation, plays a crucial role in the secondary mortgage market. It helps ensure a steady flow of funds into the housing market by standardizing mortgage products and practices across the country.

Freddie Mac indirectly influences neighborhood development, supporting markets for single-family homes, multi-family complexes, and rental properties. By maintaining a robust secondary market for mortgages, it contributes to economic stability, particularly in challenging financial climates. Since its establishment in 1970, Freddie Mac has been pivotal in setting industry benchmarks for mortgage lending and risk management, helping to lower interest rates for mortgage borrowers and facilitating broader access to homeowner financing.
