This is putting the cart before the horse.
Agree with this. Your parents may only be declaring $25K, but they own a business. If your goal is med school and you can graduate debt free from an in-state college with money in your pocket, take the money and run. I don’t think you’re going to find that good of a deal anywhere else, and assuming your parents aren’t planning on contributing to your college costs, that’s the deal you need. It might also allow them to buy that house, which is something worth considering IMO. If I were in your shoes, I know that’s what I’d want for them.
Best of luck.
