Gosh, that’s a big question — and I don’t know your overall circumstances or your age. But ask yourself why you want to be responsible for the current home you own, especially if you’re not living there. As a single person, you can exclude $250,000 in capital gains on the sale of your residence. If you pay off your mortgage balance, you could put the cash literally in the bank (not in risk investments). Then you can move forward in your life — deciding where to live, where a future job might take you, etc.
