The thing that sound wrong is that your family is putting her debt on you. However, that may be due to how you explained the situation. Is anyone else helping or just you? If it just you, then don't do it. You are young and have a future to grow. Your father's future is much more certain than yours, let HIM sell it off. More to the logical point if it is just rent then suggest that she move in with your father or mother. If it is because she lives in a medical facility, maybe you can get her some kind of subsidy to make her rent more affordable. My question is, why can she just now not pay rent? Did the rates spike or did she live beyond her means?
