I agree with PP that part of it depends on what else is in the picture. And in your case, keeping the option open to buy a bigger house is costing you money. I’d look at the interest amount it’s costing you and decide if it’s worth it to keep your option open. Maybe you should just make a firm decision about whether you’re going to buy another house or not and go from there.
I paid off my loans last year because they were really bugging me, even though financially it would have been better to put that money toward my mortgage principal. I don’t regret it but I recognize it was an economically irrational decision.
