Accelerate mortgage payments or invest?

Here’s the thing: Mortgage debt repayment is investing. Your return comes from interest savings that accrue by paying down the principle portion of your debt. So paying down principal today will save you a bit in interest today and a lot tomorrow, especially if your debt is likely to still be outstanding five or more years from now (like many mortgages).

Sometimes, people choose to invest instead of paying down debt. If you think you can earn a higher rate of return on your investments than the interest rate you’re going to pay on your debt, in theory, you’re better off. In practice, it depends.

Over the past 30 years, the 5-year posted fixed mortgage rate has averaged about 7%. Canadian stocks and bonds have both returned about 9% annually on average, while U.S. stocks have returned about 10%.

And while it doesn’t seem like much of a feat to earn better than 3% returns on your investments relative to current mortgage rates in the next five years, fixed income returns are low and stocks have been in a 5-year bull market, so high returns in the next five years may arguably be more challenging than in the past five years.

Mortgage debt as an investment

If you and your husband are going to invest instead of paying down your mortgage, I’d suggest you do what you can to make your mortgage interest tax-deductible, if it isn’t already. If it’s not, you can consider using your non-registered investments to pay down mortgage debt. If you then borrow to invest, the interest is generally tax-deductible. I’m always leery to borrow to invest, but you’re really already doing it if you have debt and investments at the same time.

Given that your investments are earmarked to buy a second home in a warmer climate, I’d make the argument that you should consider investing in that second home now. If you invest in stocks and bonds with the intention of then pulling out that money to buy the home, why not consider investing in the home in the first place?

If that warmer climate is in the U.S., prices have started to rebound, but are still quite low based on a number of metrics. Beyond that, there are a lot of baby boomers who are dreaming of a vacation property down south these days. Turning those dreams into reality likely means rising prices.
