I know it's tempting to beat the living **** out of the little freeloader,
but if you think you're mad now, wait until a judge orders you to recompense
him for his belongings, "pain and suffering," etc.

You can do no wrong by filing a formal eviction. It doesn't cost much and
covers your ass. ASSUME he has tenant's rights, because even though laws
vary from state to state, he does have rights - rights you gave him. The
fact that he doesn't pay and broke the verbal contract is of no consequence
at this juncture; you still have to do a legal eviction, just as you would
if you had a written contract.

Contracts don't mean a thing once you've provided a space for another human
to reside. As such, it has to be inhabitable. So don't cut off his
electricity or water, much as you want to (and in my opinion, have a right
to!). Don't dispose of ANY of his belongings. Go the formal route. In the
long run it will benefit YOU. Next time don't let anyone live in your
property without a legally binding contract, background check, and
deposit/first month's rent up front. I speak from experience; I was a
landlord for 15 years.
