Some can tell you what color you can paint your house and what materials you can use on your roof. 

You will be able to see the floor plans, colors and finishes that are selling right now.

I had a tenant once who would ask me almost monthly to put down new flooring for him because he didn't like the color of the current tile.

I'd consider it similar to using strong paint colors in a property, some will hate it, some will like it but using colors that almost everyone finds acceptable will appeal to the largest group.

In most of our rehabs, we opt for a light-colored countertop that steers away from brown colors that were so popular just a few years ago.

At the time, every other flipper out there had been installing white cabinetry but we wanted to separate ourselves from the pack so we went with a darker, pepper-corn color.

But I do appreciate any color you can provide.

@Andrew Benavides to give you some color, my wife and I first lived together in an old 4 family. 

New electrical from the utility pole to every switch and outlet.All new plumbing.Opened the floor plan, new kitchen, new bath and new floor throughout.Added finish details and some nice interior color choices, at least, I think so...

What's easy is done to death, I don't know any professional investors who rely upon letters of any color to drive leads.
