Most seem to have Moen water valves & solid-surface showers of some sort.

Sounds on the surface this is a great way to place your properties. 

It's also not harsh on most surfaces.

My experience is if things are this messed up (tenants paying each others utilities without knowing it) you are just scratching the surface.

Debris should be removed from the roof surface to prevent premature wear and proper drainage.- Repair: Pointing of deteriorated mortar between the bricks of the exterior walls is advisable throughout to prevent further deterioration (front and rear).- Repair: Damaged brickwork at the rear wall should be repaired to preserve the wall.- Repair: The loose siding at the front porch roof line should be re-secured to avoid wind-damage and varmint/pest entry and moisture intrusion...

Yes, they CAN scratch but on the whole, they hold up much better than carpet, or most other surfaces.

The old hydronic 8ft (disgusting) base board heaters were inefficient & the place always felt chilled.In an adjoining unit I installed a kick-space unit under the bathroom vanity & the girls love it.

If you think it does, then you don't understand who you are, and it won't matter what you call yourself.If you paint houses, but don't like the term "painter", it won't matter if you tell others you are a "surface color coordinator"...you still paint things.

Call Surface Concepts just have it recoated.  

We are in a new age of organized crime, where criminals do something sooooo nearly legal that appears moral on the surface, but when actually analyzed is either a scam or fraud.
