@Ryan Dickerson, while you will ultimately need to either make a somewhat blind leap or hope you can find a contractor that will walk your properties, one piece that I will add is: YOU need to know what type of finishes you are looking at, and understanding their material costs.I.e. are you going to do carpet, LVP, or true hardwoods?  

Schedule your carpet and furniture steam cleanings. 

Typically people who really have done something extraordinary will tell people who they did it.It's not impossible, you could buy and close, do a two week paint and carpet rehab, find a cash buyer right away, close in two weeks, make 40k, not impossible, but highly improbable. 

WIP Inventory > Tile  $500But let’s say I’ve spent $30k on this rehab and I have two dozen different accounts in WIP (tile, carpet, drywall, etc.)

All we had to do was wipe down the walls and clean the carpet.

.$12K turn on large home, included new high quality carpet and full repaintHere lies the major deviation: Property type matters.....I have NO LARGE HOMES, I install NO CARPET.  

paint and carpet aren't enough right now. 

They actually came out and cut samples from the carpet and had an investigator interview us (we were not even in the country when this took place).  

My carpet had a few stains and the walls had few touch-ups.

For another vacant unit, we did some light renovation with new paint and new carpet.
