How do you pay your mortgage off in two years?

Multiply the balance of your mortgage times your interest rate. Add this number to your balance. Divide by 24. Make that payment each month. This will get you close. Your very last payment will be off slightly so before your last payment, get a payoff statement(not a balance inquiry)to get the exact amount required to pay off your mortgage. For example: $100k * 7% = $107k $107k / 24 payments = $4458.33 per month. In this case, the ACTUAL amount needed to pay this would be $107,454.24 but that was figured using a financial calculator. In reality, the above example would leave you $454.24 short of a complete payoff on your last payment.
