How is not paying off mortgage better in normal circumstances?
Lets do the math, using your numbers. We start off with $100K, a desire to buy a house and invest, and 30 years to do it.  Scenario #1 We buy a house for $100K mortgage at 5% interest over 30 years. Monthly payment ends up being $536.82/month. We then take the $100K we still have and invest it in stocks, earning an average of 9% annually and paying 15% taxes.  Scenario #2 We buy a house for our $100K cash, and then, every month, we invest the $536.82 we would have paid for the mortgage. Again, investments make 9% annually long term, and we pay 15% taxes.  How would it look in 30 years?  Scenario #1 Results: 30 years later we would have a paid off house and $912,895 in investments Scenario #2 Results: 30 years later we would have a paid off house and $712,745 in investments Conclusion: NOT paying off your mortgage early results in an additional $200,120 in networth after 30 years. That's 28% more. Therefore, not paying off your mortgage is the superior scenario.  Caveats/Notes/Things to consider Play with the numbers yourself:
