history: when my friend wanted to move into my house that i have up for sale.  My friend asked to move into my home that I am selling and live there for free until she can find a place.  Yikes_comma_ that's a tough place to be in. She's very forward for asking something like that too.
current: I know shes a pretty close friend, but its still scary the thought of letting someone move in. They say dont deal with friends or family when it comes to business. 
next: They do and you never know what could happen, let's say you guys get into a fight and then she trashes your house! Not a good outcome!
