The truck you take to the closing should tow a trailer with an excavator on it.....
and yes, I know, you can't do that. But the next stop after the closing is the courthouse to file the judicial eviction.
(it may actually be cheaper meet with the squatter $1000 cash in hand and offer it to him if he is gone the next day)
I will say, NEVER HAND THEM MONEY AND TELL THEM BE OUT TOMORROW. Only ever give someone squatting money when they are gone. Best bet is to have someone legal or police there to witness and can testify to what occurred. A lawyer or police, not your best friend from high school. The money is only for moving expenses, not a bribe. Again, DONT EVER GIVE THEM MONEY UNTIL THEY ARE ACTUALLY GONE!!!!!!!
