They don't care about the noise, or you, and noise violations as you being the landlord are probably not a court worthy eviction cause,, especially with out police calls.. you don't have to say why your non-renewing just your non-renewing. 

I don't want to play police, judge, or therapist.

You're the guy whose hand they're grasping to stay out of the abyss.I think you'd really be surprised how much the most hardened police officers and child welfare caseworkers will typically respect the difference between a responsible landlord of low-cost properties and a slumlord.

@John Thedford Personally, I have no problems with guns in the hands of law-abiding citizens but I'm also biased since I grew up around guns (my dad was a police officer). =)

There are good and bad landlords, just like there are good and bad teachers, police and doctors.

I'm good about policing my workload and productivity, so my manager doesn't have an issue with my going across the street for 45 minutes up to 4 days a week.

LA relaxed some of its building rules, builders came in and built a lot of higher end units, the police moved the bums along out of the area and high end restaurants and shops started to move in.
