There are still beautiful things in this world but also evil forces and disturbed people that you have to watch out for.

Very sad and disturbing.  

Every night, as his security lights disturb your view of the clear starry night, you'll curse him under your breath and get a little angry.

Also states: do not disturb occupant.

Stay out of it....Tell the other tenant that if there is a disturbance they are concerned with, then call the police and let you know the outcome.Unless this becomes a very regular issue...with multiple police calls..... where they are violating the lease in regard to infringing on the other tenants right to peace and quiet....I wouldn't even contact the fighting tenants.Do not become the outlet for a tenant to call you for every petty issue

There is also the need for them to access the area for maintenance at any time without accessing the building and disturbing the residents which this setup helps accomplish.

I’m helping homeowners without disturbing the market that typical home buyers are looking around at.
