I tried to offer him money but he knows that if he sticks around it would be at least 5 free months of free rents.What Im curious is if I do the steps above would the cops arrested right away after he called the cops or does he have to sue me to get me arrested?

I thought lack of utilities would help.Here once the Sheriff serves the Writ they have 24 hours to vacate, if they don't leave or are found back on the property again they will be arrested for trespassing.

Even Philly is trying to disconnect as many storm sewer connections as possible.And when I say it's illegal, I don't mean they will arrest you.

The final time, the guy got arrested and went to prison for a year.

That way if there are I hate to say it but they get arrested for breaking in.

Not to mention having to listen to long stories about how its someone else's fault for their eviction, job loss, or arrest.

People you arrest are back on the street before you complete the paperwork.

(I would be changing the locks any way at this point)Of course if she breaks into the house, the police may not arrest her.

Never did get anyone arrested..  

@Michelle Chabot Welcome.That was an inexpensive lesson.As far as screening, once I've got a deposit (I always check with their bank to see if it's good) and an application, I run the Credit Check: Credit, Arrest Record and Housing Court information.
