Pay Off Your Mortgage or Invest? Don’t Miss Out on Thousands!

Should you pay off your mortgage early, or put that money to work somewhere else? It's one of the most common questions I get — and one where the emotionally satisfying answer and the mathematically correct answer are usually different. Let's do this honestly, because the wrong default can cost you six figures over a couple of decades.

The core math

Paying extra principal "earns" you exactly your mortgage rate, guaranteed and tax-free-ish. If you locked a 3% pandemic-era rate, every extra dollar you send the bank earns... 3%. Long-run diversified market returns have historically run meaningfully higher, and real estate in our corner of the world has compounded harder still — Park City's 20-year appreciation average sits around 6.7% annually, and that's before rental income or leverage. Sending extra money to a 3% loan while those alternatives exist is a choice to earn less for the feeling of safety. Sometimes that feeling is worth it. Just price it.

When paying it down wins

The calculus flips in real situations: if your rate is 7%, a guaranteed 7% return is genuinely hard to beat after taxes. If you're near retirement and want your housing cost at zero when income stops. If carrying debt costs you sleep — peace of mind is a real return, and I never argue anyone out of it. Or if you'd otherwise spend the money rather than invest it, forced savings via principal beats no savings at all.

The third option nobody mentions

Here's the one I care about as a real estate guy: that extra $1,500 a month you're debating? Accumulated for a couple of years, it's a down payment on an investment property. Rather than de-leveraging a cheap loan or buying index funds, it can control a second appreciating asset with rent paying the mortgage — the exact "one house changes your retirement" compounding I've broken down elsewhere on this blog. Leverage on a low fixed rate is the most powerful wealth tool most households ever touch, and prepaying it is voluntarily handing the tool back.

The honest answer is personal: your rate, your timeline, your stomach. But make the decision with the opportunity cost on the table — not just the warm feeling of a shrinking balance. If you want to run your actual numbers, including what that money could do in a Park City or Salt Lake rental, I'll happily sit down and do the math with you.
