Agreed on nixing the extra legal means. I had the exact same thing happen to me. This idiot moved in below me and would take his friends out on the balcony at 2 AM. He seemed to think the place was a "flop house". I talked to him but he was only patronizing. I spoke to my fellow neighbors and they "claimed" they heard nothing.

Every time he made noise I complained to the condo and they fined him and finally one night he and his friends came back at 2 AM. They opened ALL the windows and were blaring the tv. They were drunk. I called the cops and the cops wisely snuck up on them and saw the open windows and blaring music.

They got ticketed for "disturbing the peace" and that was the end. I forwarded the police report to the condo and the guy sold.
