house scheduled to close next week - occupant refusing to leave

[Brent Hill]

scheduled to close on a house next friday. Occupant(newphew of owner) is refusing to move until he has the money for a place to buy. I told him we can't close until the property is vacant 2 days prior to closing. I have offered a small amount of cash, found a trailer with land with owner financing and I know is mother is willing to put him up for a while until he finds something. My contract is good until the end of month and I really don't want to mediate or pursue any legal action if I don't have to. I have a call in with the owner(occupants uncle). Any ideas or suggestions?
