After you get that house under contract, don’t go out and buy a lot of furniture.

Big purchases done on credit could push your total borrowings so high that you no longer qualify to get that previously approved home loan! Yep, your mortgage company will check your credit again right before closing.

Next, try not to inquire about, shop for or take on new credit obligations during the period between your application and the scheduled closing. If you seriously want that new loan, keep your credit picture simple — no significant changes, no additions — until you settle on the mortgage.
