Best thing is to do, play dumb and deaf. Unless you see a life & Death situation. Then it is a moral thing you have to do. One thing I have found
out about tenants, they will have everything but nice to say about apartments during the inspections. You want to talk to some one who is an expert about the right and wrongs about buildings, tenents, etc. Talk to a long term tenant.
I remember one time I did apartment building in Rochester, NY. I thought this lady was either sister to or twin to the one in Elmira, NY. The same way talking, carrying on and the apartment. She complained about everything and everyone but herself. What she did was absolutely 100% good. We had to walk through the house sideways. It was funny and I laughed. I was with the owner and she was getting all over him. Then she looked at me and started in. I told her, I think I met your sister in Elmira. She laughed and poked me in the side. So this business can be fun. Just got to be nice.
