HOA liens are a bitch. So far I've only had two issues with my neighbors, the one on my right (facing the house) had a penchant for mowing big half-circles in my lawn until I politely reminded him where the property line was. No more issue. The one on my left was harboring a fugitive boyfriend for a while, I know this from a knock on my door at 7:30AM from a guy in a tac vest with a shotgun holding a picture of the dude, then seeing 3 unmarked Crown Vic's on the street. The previous day, the dude himself was at my house trying to sell stuff he stole from her place, although I didn't connect the dots at the time. I politely reminded that neighbor that I am well armed and will not hesitate to put 2 into any dumbass that decides to try any shit at my house. Problems solved.
