Long terms rentals will have repairs from time to time, but if it is a true emergency, you are going to be calling someone (eg plumber) to come in and fix something, so that is no different than your own home (minus the clean up). 

That is an interior heavy rehab, i.e. remodel kitchens and baths, new floors, fresh paint. 

Reface cabinets, new countertops, glue down flooring and fresh paint.

A good cleaning will make it pop brighter and couldn't hurt. 

Look for something that needs cosmetics work, such as new flooring, paint, cabinets, etc, as this will help build value and get the most rent.   

The rehab would be mainly cosmetic, floors, kitchen, bathrooms, paint.

I.e. for carpenters, knowing how many doors need installed, all trim installed, addition of quarter rounds AFTER floors are refinished, wood filling of all nail holes and caulking of all gaps in trim.Tile installers: installation of wonder board, with all seams taped and cemented.  

Clean and easy.

Like when I didn't pull permits, I had to rip on the cabinets and tile and then abate asbestos that was under the kitchen floor tile. 

This included installing new tile flooring at the front of the house to enhance curb appeal, upgrading the electrical panels for safety and efficiency, and putting on a new roof to ensure long-term durability.
