You are going to get a loan on a house for $565,000, you are offered a 5.9% interest rate for a 30-year loan and a 5% interest rate for a 15-year loan. The Fidelity 500 Index Fund (FXAIX) has had an average annual return of 12.95% over the last ten years (real value). If you take the difference between the two loans and invest it into the Fidelity 500 Index Fund (assuming the same return), how much money will you pocket in 15 years after you pay the loan of the 30-year mortgage?
