Say you have a mortgage and want to know exactly how much you'd need to pay to satisfy the loan. A mortgage payoff letter will tell you that magic number.A mortgage payoff letter can come in two forms. One form tells borrowers the remaining principal amount and interest they have to pay to close out the loan. A 10day payoff refers to the time it takes for your new lender to pay off your old loans during a refinance. Do you need a loan payoff request form? A lender's payoff statement or letter will show the amount you need to pay to completely close out the loan. You may obtain and instant payoff through the "Documents" tab and "Payoff Statement". A mortgage payoff letter will include the appropriate fees and the amount of interest through the day you're planning to pay the loan off. It's vital that title and escrow professionals find out the exact amount owed at the closing.
