It’s never a good idea to try and screw somebody over that’s given you a good deal, not that I’m saying that’s your intent; however, that being said, I would pay the loan and not take advantage of it, just to be safe. It’s good for your credit score, it’ll erase debt, and you don’t know what could happen in the next few years. Medical accident, have a kid, get married, can’t work, get paid off, something, anything that can happen to somebody. You wouldn’t want some $12.5 grand just hanging around in debt. No matter what, that’ll have to be paid off some way, some how. Better to get it out of the way in my book, especially if you can right now. If you have a financial planner or fiduciary I’d talk to them too for questions like this. Not degenerates like me. Hope that’ helps. Not trying to scare you, but I don’t ef with debt.
