If your loan is with Bank Midwest located in Minnesota, Iowa or South Dakota, use our online form for a convenient way to request your loan payoff amount. You'll need to request a 10day payoff letter from your current loan servicer, which you may be able to do online.In addition, within five (5) business days of receipt of a payoff, Minnesota Housing must receive the corresponding Loan Paid in Full Statement form. 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 lender's payoff statement or letter will show the amount you need to pay to completely close out the loan. Mail the funds to the address listed in the payoff letter. Wire the funds with the wiring instructions. Do you need a loan payoff request form? Notify your lender via phone call or a written letter of instruction to put that extra cash toward your principal.
