I am buying a townhome in PA as my primary residence. I will be making the full downpayment, all costs and will be paying all utilities/taxes/HOA going forward. My parents also live in PA but they are struggling due to poor economy. Dad has minimal work and mom is unemployed. Parents are soon getting rid of their home in a sale and may need to move into my Townhome. I will not be charging them rent as they can't afford it. The only payment I ask from them is to clean my home. What worries me is that my dad has a lot of debt and may potentially have to declare bankruptcy while living in my home. Will that affect my homeownership/finances? (I have no debt shared w/ him). Should i have him sign something (ie $0 rent tenant form?) or make it so that he can't affect my credit or get me sued?
