Which of the following entities is involved in the primary mortgage market?

The primary mortgage market is where loans are originated, meaning it includes entities that provide financing to home buyers directly. Credit unions are a type of financial institution that can serve this function by offering mortgage loans to their members. They typically provide a wide range of services, including personal loans and mortgages, and they are directly involved in the lending process to consumers looking to buy homes.

On the other hand, while Fannie Mae and Freddie Mac participate in the secondary mortgage market by purchasing loans from lenders to provide liquidity and stability to the market, they do not originate mortgages themselves. Ginnie Mae also operates in the secondary market, primarily ensuring that mortgage-backed securities are backed by government loans. Thus, in the context of entities involved in the primary mortgage market, credit unions are the correct choice, as they directly engage with consumers to make mortgage loans.
