I just wanted to have a leg to stand on when I speak with them and not be completely in the dark.

As long as you follow fair housing rules, and don't use race, color, national origin, religion, sex, familial status or handicap in your criteria, it is your decision.

Normally I would say add some more artwork to the walls to give it more color and pop, but it might not be necessary seeing as you have a short stay long term rental now. :)

I honestly am in the dark with new construction costs though from scratch. 

Use a standard color and save the paint code saving even more money as you can just touch up bad areas and will match perfectly.For higher rehabs or my own house, flat on the ceiling and eggshell for walls. 

That's a walk on the dark side!

While you can put lipstick on, change carpet and paint color, floor plans become dated, boring, less functional, if you begin in a 75 year old property, you'll have a 100+ year old property in an old section by the time you get it paid off.

It is very easy to make your own in any size/color you need.

I can also update the statuses of the deals (color coded) so they can see what's going on.

The renovations all look good, the same paint colors, the same wood floors, the same 5' kitchens (which I imagine is common for turnkey providers).
