If all goes as planned, we should be netting ~$240k in the next month or so after selling an investment property. We will need to pay capital gains tax/depreciation of about $52k, but that won't be due until next year at tax time.
We owe about $175k on our house (worth about $450k -- yes, we bought it before the prices shot up, so no, we didn't pay anywhere near that much), with about 15 years left to go on a 20-year loan @ 3.875, paid biweekly. So we could pay it off with enough left over to pay the taxes. The mortgage payment is pretty low (<$1200/month), and overall, we'd save ~$55k in interest by paying it off early. If we invested the money, we'd earn about $10k a year if it earned 5% -- but could lose some if the market goes down, of course. If we pay it off, we could save the $1200 a month that we've been paying and invest that. Even if we earned nothing on that money, we'd save up the payoff amount in less than 10 years.
We have been inclined NOT to pay it off, but now I'm wondering if it's better to do it. We've been mucking around with this mortgage ever since we bought the place in 1999 -- refinanced a couple of times for various reasons, thinking we were being clever but really probably it's all been a wash. I am not working anymore except for a little freelancing; husband is and is planning to continue, and his income is more than sufficient for our needs. We also have really enough to retire on if he decides he doesn't want to work anymore, unless some crazy extra expense comes up. I'm 56 and he's 54. OTOH, that's a lot of funds to be tied up in a house.
So what do you think? Is there anything I'm missing here? TIA
