Overpay the mortgage or invest the difference?
Chapter 1 of 5
The idea
Every extra $100 on your mortgage earns exactly your mortgage rate. Guaranteed.
The trade-off
Overpaying gives a certain, tax-free return equal to your mortgage rate, and lowers risk. Investing has historically returned more over long periods, but can fall, and money is locked in the house either way unless you remortgage or sell. Check for overpayment limits (often 10% a year) to avoid fees.
Predict first
Mortgage at 4.5%. Investments might average 6–7% over 20 years. Which wins on paper?
