Buying a home with a squatter in it....

[Ryan Dossey]

I have a family that I bought 2 houses from call me on a 3rd home. It is a 1700 sqft 4/2 with 1700 sqft. It has a massive yard and is on a quite street. The problem is this one has a relative who is squatting there. She has been squatting there for over 20 years. The home was owned by her father. He grew ill and couldn't get her to leave. The executor of the estate has asked her to leave and had her served a notice to move. Before they evict they want us to buy it. They are worried that when they go to evict she will take it personally and trash the home. The trick is the home is worth 160k and I can get it for 50k. However... How can I see the inside before agreeing? What legal battle am I looking at here? Cash for keys?  

I have never done an eviction. What would you do?
