Mortgage brokers arrange transactions rather than lending money directly. In other words, they find a lender for you. A broker’s access to several lenders can mean a wider selection of loan products and terms from which you can choose.

Brokers will generally contact several lenders regarding your application, but they are not obligated to find the best deal for you unless they have contracted with you to act as your agent. Consequently, you should consider contacting more than one broker, just as you should with banks.

Whether you're dealing with a lender or a broker may not always be clear. Some financial institutions operate as both lenders and brokers. And most brokers’ advertisements do not use the word "broker." Therefore, be sure to ask whether a broker is involved. This information is important because brokers are usually paid a fee for their services that may be separate from and in addition to the lender’s origination or other fees. A broker’s compensation may be in the form of "points" paid at closing or as an add-on to your interest rate, or both. You should ask each broker you work with how he or she will be compensated so that you can compare the different fees. Be prepared to negotiate with the brokers as well as the lenders.

It's best to get information from several lenders or brokers before you commit to a mortgage.
