Thrifts offer savings accounts and other services as well as mortgages.
Mortgage bankers do nothing but lend money. Mortgage brokers are not bankers and have no money of their own to lend. They act as middlemen, working with a number of lenders to find a loan to match a particular borrowers needs. By state law, brokers work for the borrower. Mortgage brokers work with many lenders including commercial banks, thrifts, and mortgage bankers.
