It went from something like the #1 property on the police dispatch log, to totally turn around.

Calculate the infrastructure cost to build and maintain per 1000 residents for:- miles of road, sidewalks, streetlights- miles of utilities: water, sewer, gas, electricity, internet- public services: police, fire, snowplowing, public works, trees and green spacesAnd then people complain about taxes.

In reading your post, it sounds like you might have a police issue for trespassing, not a court issue with an eviction.

@Hoai Nguyen suggest modifying your current lease to cover multi-family setup.Parking, shared access, police report required for landlord to get involved in disputes, etc.

You should contact the FBI or your local police department, tell them what you're being told and see if they are willing to take an interest.
