In my area we are a little slower to come around to the newest trends, but your color palate seems about right for the latest. 

I t was very dark inside and needed a lot of electrical updates and TLC What was the outcome?

I painted the walls a neutral color and painted the trim and doors white covering the old dated wood trim.

@Calvin Jordan never let an incoming tenant dictate/ pick paint colors and Never allow a tenant to paint.This was a lesson learned hard after the first few move outs, causing too much extra expense and time between tenants.

I like a dark brown that kind of looks like dirt, if you have the tile to pull it off, because after a year of greasy, dirty feet and shoes it will be the color of dirt even if you seal it.

It takes no thought process into which color which places walls are .

I know this is a shot in the dark but anything will help!
