Consider top to bottom. Neatly stack cartons, etc. If the storage spaces are dark and dreary, a coat of paint or extra lighting can do wonders. We all love closets and you can make them look bigger by having them clean, neat and well organized. Get rid of folded clothes and cartons that take away from the spacious look.
Bathrooms sell homes.
Make bathrooms sparkle. Clean stained sinks and bowls. Repair any damages or discolored caulking around bathtubs and showers. Be sure towels and area rugs are bright and sparkling. Make certain all light fixtures and bulbs work.
