Install fresh drywall (where it makes sense) and repaint a nice white color.

I am somewhat picky though because I know I can be, as I pass any basic landlord tenant screening with flying colors.  

If you start drawing first without knowing what lines you can color in you may be wasting time / money.

If you have serious cracks with large gaps or it is uneven, then you might want to consider some options, but it sounds like your problems are not big.I would consider doing the paint job if the current paint is bad or the color is ugly. 

Listing would include high quality exterior & interior renderings, floor plans, description of finishes, plus something like "still time to choose your own counter tops, vanities, colors etc... home under construction and finished Sept."

If all you post are wins and not the lessons you're giving people a rose colored view of REI.

It was built in 1997 and everything is original and including the strawberry wallpaper, different oddly colored rooms, cheap appliances and worn out wood floors. 

@Adam Horvath I think you're right about the kitchen remodel, the other simple fixes that you can do to get a great bang for your buck is to replace the bathroom fixtures and maybe (if this makes sense for your area) change the paint color to something thats a bit more in demand

What's their favorite color?

“I expect this to be installed, want this to be painted this color, want this appliance swapped out.”
