I am interested to see what other peoples perspective is on this situation. I had a similar situation in Florida with individuals residing at the residence that had no permission to be there. According to Florida Law, I had to go through the process of evicting them just like any other tenant. I served them a three day notice to vacate or pay. If they failed to do so an eviction process would have begun being served to them at the location. I then had deputies escort me to the property (I had to fly in from California) and clear the premises to ensure its safety. Naturally this type of tenant stole whatever they could get their hands on (fire extinguishers, refrigerator, shelving, closet systems, concrete patio sets, misc. paint and building supplies) and drew all over the walls. It may be prudent to have a way to "watch" them to ensure this doesn't happen. This was a miserable situation and I don't wish it upon anybody. I hope this helps and I hope your situation turns out better than mine without any vandalism.
