it's tough. there's only a few things you can do.
1) call them, leave them a message that they didn't pay their rent for the last month. tell them you have kept a record and they forgo their damage deposit.
2) tell them you want to resolve this without going to small claims court.
3) you need their new address so you can serve them documents.
4) once you go to small claims court, u'll most likely win. HOWEVER, it's the next step that's hard. a) you need to garnish their accout b) their salary.
u don't have their new accout info. so unless you're well connected like me, you won't be able to find out any details from their current bank accout. (you also need their FULL name)
if you want to garish their salary, you'll need to know his banking / salary schedule before you can garish.
i have 2000 that i need to collect from tenant, but .. meh.. it's a lost cause since he's unemployed.
Arguing on the internet is like running in the SPECIAL OLYMPICS.
Even if you win, you're still retarded.
