The interest you pay on your mortgage is usually tax-deductible. This deduction can amount to significant savings, especially if you are in a higher tax bracket.
Other investment opportunities will provide a better return than paying off your mortgage early.
You may be carrying other debt with a higher interest rate than your mortgage. Pay off this debt before aggressively paying down the mortgage.
Inflation can offset the amount of interest saved by paying your mortgage off early. If you have a low rate on your mortgage, say 4%, and inflation is 7%, your real interest rate you’re paying is 33%.
