Are these guys renters?
If so, I can't believe they've managed to go this long without already being evicted. Amazing.
We had a renters in our house in Orlando a few years ago that were great for about 3 years. Always paid on time, kept the place up very well, never had a problem. Then they had the wife's brother move in when he was down on his luck. Within a few months, he and his tweaker buddies all but trashed the place to the point to where the actual renters did a midnight move out and left him there. Since we were 3,000 miles away, we had no clue what was going on. After the first rent check didn't arrive, I tried to contact them with no luck. I waited a couple of weeks and still nothing.
Eventually, I had my brother drive down from Tallahassee to check in on the place and the tweaker/loser basically threatened to shoot him when he knocked on the door.

He went on to tell him that the people he was looking for didn't live there and to stay the fuck off of "His" property.
I finally tracked the couple down and got the husband on the phone, he told me that the brother in law had been in and out of jail and had a drug problem (duh) and that he had brought so many of his problems into the house, that he and the wife bailed out fearing for their own safety. He apologized, but didn't offer any help in getting rid of the guy or paying the past due rent...
So I set about trying to evict this ass clown from 3,000 mile away (no easy task). Eventually, I had to fly out there several times to deal with it. By the time I got them out of there, they had completely FUBARed the house. Holes in all the walls, fixtures missing and broken, carpet destroyed, yard destroyed. A total mess.
It took 4 months to get them out and at that point, when I tried to go after him for the damages, *THIS IS THE BEST PART* WAIT FOR IT...
WAIT FOR IT...
He tried blaming the damage on a Hurricane that had gone through the year before and said that I had been aware of the damage all along and had refused to fix it.
Needless to say, I got nothing out of this deadbeat, or the original renters.
