When you pay too much into escrow, you have an escrow overage. This can happen if your mortgage provider miscalculated the amount of money needed to cover taxes and insurance obligations. When this happens, the mortgage company will issue you a check for the difference. If you do receive a check from the lender as a result of an escrow overage, it’s a good idea to put it directly into your savings account so it’s there if you end up in an escrow shortfall situation.
