I purchased part of the materials for my first renovation, which was local - kitchen cabinets, countertops, bathroom vanities, faucet fixtures, shower rough in valves, tile for bathrooms.  

They will note if anything doesn't work, and usually the A/C doesn't come on due to the low amount of power coming in, and very frequently the water lines won't hold pressure because a faucet was left on when they drained the system.

They will handle the basics like painting and lock changes when there are turnovers, fixing faucets and other routine maintenance. 

I had a tenant (not S8) that thought it was OK to let the faucet leak and run across the basement floor.  

I recently learned they are being sued because one property they managed one of the people touring it, trashed the place and stolen everything including light fixture/faucets.

Don't forget to change all your faucet aerators and shower heads to low flow it makes a huge difference as well as far as water usage and saving HOT water. 

Clean the strainer in all your faucets ($0). 

I mean you technically require a permit to replace an outlet or sink faucet hahaha

permits to change a faucet/light fixture thats crazy. 

For low income rentals, I always put in the CHEAPEST faucets that Lowes has, WITHOUT sprayer.
