In which market may a lender sell a loan that a mortgage banker has previously originated?

The secondary market is where lenders can sell loans that have been originated, such as those created by mortgage bankers. In this market, loans are purchased by investors, which can include banks, insurance companies, and other financial institutions, allowing the original lenders to recoup their funds and continue making new loans.

The primary market, in contrast, involves the initial transaction where borrowers obtain loans directly from lenders. Once a loan is made in the primary market, it can then be sold in the secondary market. The tertiary market is not typically a term used in the context of mortgage lending and does not involve the buying and selling of loans like the secondary market does. Lastly, the wholesale market refers to a type of operation where loans are offered in bulk, usually to other mortgage lenders, but it does not describe the general process of selling loans after they have been originated. Thus, the secondary market is the correct answer because it is specifically designed for the trading of loans post-origination.
