The mortgage broker is a middleman who searches for the best mortgage loan rates on behalf of clients. On the other hand, loan officers work for banks and other financial institutions to help customers apply for loans. A mortgage broker is an intermediary between the borrower's lender and the mortgage broker, while a lender officer works directly for them. Because mortgage brokers have greater access to lenders and products than loan officers they are often able to find better deals. Loan officers might be better equipped to approve loan applications because they may have a greater knowledge of the products offered by their employers. A key difference between mortgage brokers versus loan officers is the fact that mortgage brokers typically receive a commission from the lender while loan officers usually earn a salary plus commissions. Some mortgage brokers charge clients a fee. It is important to compare the fees and rates of different loan officers and mortgage brokers before you make a decision. Before you sign anything, it is important to ask questions.
