Finally: *DO NOT* let tenants attempt to fill holes or do touch up themselves.

These two demographics are projected to be long term renters which will help keep vacancy rates low for years to come.In recent years, Pittsburgh has become a tech hub in its own right, attempting to create a dynamic job market similar to Silicon Valley.

Quote from @Bob Avery: I don't recommend leaving a space blank because someone could later attempt to add something in.

Definitely follow the regulations in the area and if permissible I would offer to attempt to find an acceptable tenant and terminate their lease when that happens but in the meantime they will need to continue to pay.

Check this link, Indy SFR Proforma, for my attempt at a proforma on a random SF property in Indy.

The water fell 3 floors, when I observed the incident my neighbor was attempting the sweep water out the back door.   

I am always fully transparent and the owner in that situation is a long standing business associate that knows my character, experiences and background, strengths and weaknesses included.

I believe only a relatively small amount of people attempt liens and notes in the first place.By volume, the most dangerous are OOS BRRRR and OOS flips, especially in cheap and very cheap neighborhoods - well below the median price.

There are many ways to attempt to collect your loss:  file a small claims complaint against them; get a judgement so you can garnish future wages/bank accounts - and the judgement will be recorded in the credit bureau. 

I have one listing that I'm able to make updates to, I just decided not to given the prior attempts.
