Congrats. Nice of you to pay off the sums that your parents promised to pay off, when your parents are struggling. Parents shouldn't have to get in (deeper) trouble to pay off their children's debt.
You might want to reconsider buying a more expensive house. Moving to another house is usually not cheap. You might need to invest a lot of time and money in making your old house look nice for sale. You might not sell your old house for what you think it is worth. You might use a broker who wants a slice of the cake. You'll need to pay a slice to the government. You'll need to refurnish the new house, buying carpet, closets, paint etc. You might need to buy a buyer/seller insurance, just in case.
We bought a new house for 2 years ago. And I think it cost us 2 years of FIRE. This was before we had discovered the website and didn't have a very concrete plan for FIRing. I regret it now. Now that we have a concrete plan, I know we'll need to downsize to get enough stash and I think this expensive house will be more difficult to sell than our old house, which was not easy to sell either.
