Mortgage Broker explained
A mortgage broker is a licensed specialist who arranges mortgages on a borrower's behalf. Rather than offering products from a single institution, a broker has access to many lenders, including monoline lenders that the public cannot approach directly. The broker assesses your situation, submits your application to suitable lenders, and helps you compare and complete the deal.
Brokers are typically paid a commission by the lender that funds the mortgage, so their service is usually free to the borrower on standard residential deals. Because they shop multiple lenders at once, brokers can be especially valuable for borrowers with complex situations, such as self-employment or a less-than-perfect credit history, where a single bank might decline.
