Should I Pay Additional on My Mortgage or Invest the Money?

The transcript follows.

This is a question which confounds many people who have excess money at the end of the month.

What you’re comparing is a sure thing – reducing your mortgage – to a not-so-sure thing – investment returns which should beat your mortgage rate but may not.

First, let me dispel a misunderstanding. A lot of people say that you should include the tax break from a mortgage, but that’s not exactly the case. If you can’t get deductions, including mortgage interest, in excess of the standard deduction, then you don’t get a mortgage interest deduction. You only get to benefit from the mortgage interest deduction to the extent that your other deductions exceed the standard tax deduction. So, in most cases, your return on investment really is your mortgage interest rate, not reduced by your tax deduction.

I can tell you what we did. I have a personal predisposition against risk. I’d feel worse about investing the difference and losing money than I would if we made money. Plus, I don’t believe that I can personally outperform the market consistently over a long period of time. So, we put all of our excess cash into paying off the mortgage.

Sure, it’s possible that, in time, interest rates could rise to the point where deposit rates would have been higher than my mortgage, and we could have created an arbitrage opportunity and made a little bit of money. However, the amount we would have made would have been pretty small, and the risk wasn’t worth it.

I can tell you that it’s a lot nicer having no mortgage. That’s a guaranteed, and unquantifiable return that you will get if you pay off the mortgage early. So, while some may argue that it’s mathematically incorrect to pay off the mortgage, I argue that the mathematics don’t quantify risk and they don’t value utility properly. You might, and I emphasize might, be able to get a better return investing the money, but you can never go wrong paying off the mortgage early.
