Its good they arrested him. Some areas give squatters all the rights in the world and treat the legal owner like a criminal. I have heard horror stories from the SF bay area.
I have several rentals and its hard not get pissed off about the legalities of the eviction process but at least in my county the judges seem to be pretty reasonable. I have had good luck but it sucks that a dead beat can quit paying and can stay and trash your house for weeks while you work the way though the system to get them out.
It get’s better.
Guess how many of these are home inspectors working for $7 to $20 a pop!
