@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?

Go over those things in person when you sign the lease and get agreement from them.When you have been a landlord as long as I have been, you realize that you can write a lot of things on a piece of paper: that does not mean that anyone will follow those directions.
