One of the reasons I don't have rental properties in Thailand.
When I rented many years ago I actually left the house in better shape than when I left, still didn't get my damage deposit back. So it goes both ways, I won't--and don't need, to rent again, and I won't rent out any properties, simple really. I've seen too many owners in this same situation, all the profits they made over x number of months/years has to be put back into the property fixing up the damage. Another problem is, it's hard to get justice either way, whether you're the owner or the renter, most times the police won't do anything unless you're rich, powerful, or both in which case they will have their hand out waiting for that brown envelope to come their way.
