The initial pre-qualification step allows you to discuss any goals or needs you might have regarding your mortgage with your lender. Getting pre-approved is next step. you will complete an official mortgage application, pay fee, and than supply the lender with the necessary documentation to preform an extensive check on your financial background and current credit rating.With pre-approval , you will receive a conditional commitment in writing for an exact loan amount, allowing you to look for home at or below that price level.
