Yes! When you make your regular monthly mortgage payment, you can include an additional amount to be applied directly to your principal. Additional principal payments will only be applied after the current month's full payment has posted to your account.
If you’re paying by check, please indicate by writing the amount of the extra principal payment on your Mortgage Account Statement coupon where designated and on the memo of the check.
When you make your payment using M&T Online Banking, you can elect to include additional principal along with your payment.
