However, I tried this exact scenario several years ago when a tenant accused my handyman of stepping on their washing machine and breaking it while fixing a roof repair.

All these homes are in southeast Georgia, all center townhouses in an HOA community where a monthly fee I pay covers pressure washing, lawn care and access to some neighborhood amenities. 

You need to also look for passive income streams , Something like a vending machine or maybe washing machines for students.

They’ve used less water than hand washing (by a factor of 5 or more) for about 20 years.

It was mixed heavily with rock, the slabs aren’t cracked anywhere thus raising it back to height since the ground underneath washed out would fix it and done right.

If the unit is built before 1978 we just use the Lead-Based Paint addendum (HUD requirement actually), and either note that a) we have no knowledge of whether there is lead present; or b) that we do have knowledge and provide documentation. 

Of course, when the leases are up, I will absolutely go to CSC's competitor (WASH), even if I get a worse deal there.  

If their deposit covers downtime and make ready, call it a wash and move on.

A quick google search would tell you to not paint before seriously washing all walls, ceilings, vents, etc., to eliminate cigarette smoke damage. 

Pruning trees, power washing the exterior siding, just little things I'm happy to pay for that might not be 100% "necessary".
