A mortgage broker can submit a loan to many different lenders and typically has access to several types of loan programs. A mortgage broker can shop for the best and most competitive mortgage rates and terms available tailored to meet a borrower’s needs. Some charge processing or origination fees. Mortgage bankers are lenders that are large enough to originate loans and create pools of loans. Some companies do not sell directly to those major investors but sell their loans to the mortgage bankers. They often refer to themselves as mortgage bankers as well.
