What are the roles or functions of a mortgage bank?

A mortgage bank primarily originates and funds home loans for borrowers, acting as an intermediary between them and the secondary mortgage market. It assesses borrower creditworthiness, processes loan applications, and ensures compliance with lending regulations. Additionally, mortgage banks may sell the loans they originate to investors or securitize them, providing liquidity to continue offering new loans. They may also offer various mortgage products and services, helping consumers navigate the home financing process.
