Touch-ups are cheaper than repainting on every tenant turn.Now, with all of that said, if I have a good long-term tenant that needs something, I might step up my game a little.

I can always touch up the paint on the walls if I get a scuff putting flooring in.

To use it on a tread, you MUST glue it direct, it can not float on a tread using the recommend nosing to finish.As for the rubber back carpet residue(the black stuff), if it presents an uneven surface to install over you must remove it completely (and you may have to repaint or touch up.)

OK, that just meant an extra step dusting everything back down and saving some paint for touch-up that's inevitable with workers still coming and going. 

Other than ripping out carpeting, putting in some floors, touching up the kitchen, fixing up the blinds and some other smaller touch ups, the rehab is not that grand in scale.

J-Scotts rehab book is great and lists order of items.Here is a rough list:1) Gut2) Framing - Roof, Siding, Windows3) Plumbing rough in4) Electrical rough in(You can run electric and plumbing at the same time, but I found it is easier to move electrical than it is a vent stack for plumbing)5)HVAC6) Drywall7) Trim8) Paint/Spraying9) Finishes & Flooring, Electrical/Plumbing Final, landscaping10) Clean, paint touch ups & Appliances

Helps with touch up.

Even to plaster it back up and touch up paint to match, isn't a big expense; but you said you were going to drywall anyways, so this is an easy fix.

Our second property will be getting some foundation work done as well as a full exterior paint and some general touchups inside. 

Without bringing an actual contractor or inspector with me, how will I know if what I see are actually problems that need replacing or touch ups?
