And by very similar, I mean that the only real difference is made by the management, cleaning, and interior design/pictures. 

my observations are:1. response is so low many kind of give up.2. they are shocked when they do get someone on the phone and are not prepared.3. delegated to robo call and call center reading from script  ( turn off)4. say they will call back and never do  :)  if you can somehow clean that up..

I would clean it up, turn it into a non-smoking property, and rent it at market rate.

My family and I have a residential cleaning business and we specialize in move in/move out cleans. 

Without a vapor barrier, it dries out in short order.Before spending alot of cash on sleuter backer, membranes and coaters, Id recommend epoxy grout, which IS waterfroof, doesnt need sealing, and cleans much easier.Me thinks there is too much over-thinking going on.

Such as cable, apt cleaning, Increase late fees.Rent is the driver.

My rules include things like no shoes in the house, clean up after yourself, shared bathrooms must be cleaned regularly.

I feel like you just have to clean them out every so often anyways.

There are variables you can add in too to make it more for short term rentals, like the cleaning fees.
