Kyanar:
What do you mean "careful tenant selection"? I agree with your sentiment about tenant management - especially with special needs tenants they need to be more active (or other social services invested) in management, but they're lessor of last resort. They don't get to "select" who gets a place, the only control they have is prioritisation.
"selection" means considering thing like disabilities, mental health, drug addiction, criminal convictions.
ie
You don't put a person in a wheel chair on a steep street
You don't put a person where they can get triggered, ie next to a gang house
You don't put an alcoholic next to a bottle store
You don't put a sex offender near a school
You don't put a white nationalist next to a mosque
Its not simply "here is a place" , people are complex hence the need for better management.
