Your Realtor is not a financial expert and is not qualified to assure you of getting the best loan. In fact the realtor will only get paid if your loan closes so the interest of finding you the fastest lender is sometimes more important than finding you the best lender. We recommend shopping for a loan with at least 2 mortgage companies before you make a decision. There are countless stories of consumers who wind up paying higher rates or getting a loan program that was not right for them because they blindly followed their Realtor's advice.
