Everything starts in the mind and to see the the out comes is where the real wealth is, them also creating some monetary wealth is whip cream and strawberries on top.

Hi Dana,In addition to paint, maybe put a strip of black indoor outdoor carpet just in front of the door (and on the steps if they are not cement).That area is going to take most of the abuse of moving (scraping appliances and furniture) in and out, as well as most of the foot traffic.Cut 3 or 4 more sheets and toss them in the attic for future use.A hand full of staples is much cheaper and faster on turns than a full repaint.Also keep in mind that is a long narrow space and Lighter colors make things appear larger, darker colors--the opposite.Good Luck!

Are they both going to spray the vent pipes and flashing to color in with the roof and the siding as needed?

They could help with color and suggestions.

The tiles adjacent to the wall and the baseboard have been removed, the drain tile put in, concreted over, and this has left a depressed section 18”wide that has a drop off of ¼” from the existing tile.For a quick, low-cost solution, I was thinking of putting floor leveler in, then painting it a similar color to the tile that’s there, then putting the baseboard.

If the money is spent on "repairs" making the house more usable, it'll probably be a higher return than painting the walls a different color and installing new lights.Many remodeling projects will have no net gains in property value so be careful how you spend the money.

I also don't do the "landlord special" where everything goes a single color (trim, walls, light switches, outlets, ceilings).  

Does color paper matter?

Kind of concerns me, and map stats in my current area are very accurate with the maps darker and lighter colors for areas of lower and higher crime.

Kept it simple new cabinet color, new fixtures, new appliances, remodeled the bathrooms and kitchen.
