Mortgage brokers have access to lenders, and sometimes wholesale lenders. It is your job to know that the mortgage broker you decide to work with are in good standing with banks and lending institutions. You have to understand that they are only looking out for their own self interest as to getting a referral fee to connect the borrower (you) with a lender; and little regard for your financial welfare.

Do your due diligence by checking up on the mortgage broker’s reputation, and comparable rates that they can get for you as a client.
