Need some good advice

I am trying to buy my grandmothers home who passed away some years ago and left the estate to her son my father. Who has personal tax issues that have not been paid. There is no lien on the house. My father is worried about putting his name on the deed because the government will take it. What is my best approach at buying the house without losing it. And I will be taking care of my father as he stays in the house to grow old

I’ll respond to you since there are no takers. Here’s your standard answer: it’s best to consult with your tax attorney. Even if you get a somewhat reasonable answer here it’s still best to do your own due diligence for something like this.
