With inflation and historically low fixed rate interest rates (<3%), no, it does not make sense.
Paying off a mortgage early is an emotional decision, not a mathematical one.
+1 on this sentiment. Even if it doesn't make mathematical sense, you should keep your fire journey moving forward in the way that best fits your own psychology.
Sure, but your psychology can change. I used to think paying off the mortgage was the way to go. One Saturday, I made my huge mortgage payment in the bank, in person (remember those days?). I was elated to have paid an extra $100 to principal for the first time ever. Next errand stop was the library. On the "New Items" shelf was a copy of Ric Edelman's, "Ordinary People, Extraordinary Wealth". The first chapter is the most concise list of reasons NOT to pay off your mortgage that I'd ever heard of. Mind blown.
I still couldn't wrap my head around it, until I began dating a guy who had much more wealth than I. Despite earning much more, he had "only" put 20% down, and was not making any extra payments on his home. It took a lot of explaining and patience on his part, but I finally absorbed the lesson.
BTW, that book is terribly dated now, but the first chapter is still pure gold. It should be available at the library and possibly Project Gutenberg, IIRC. The first chapter is a quick read and it's still all you need to know. Unless you're hard-headed, like I was.
