It depends on what your dad wants to do with the house. It is his, not yours. He could donate it to his church if he wants.
Sorry about your financial troubles, sounds like your dad has gone above and beyond the call of fatherhood. Asking about your rights implies you want some advantage over your dad. That doesnâ€™t sound right to me after everything heâ€™s done for you, well, regardless if heâ€™s helped or not, it doesnâ€™t sound right.
I suggest you stop calling it â€œmy homeâ€ unless your dad says it is your home, offer to buy it from him.
