If you are thinking about remodeling in order to increase the selling price of your home, think carefully. Most remodels do not return the money spent. Check out this website to find out the cost versus return of common remodel projects in Portland.
What does help? Anything that makes your house look fresh and clean: new paint, clean/new carpets, refinished floors, roof and window cleaning, etc. You might consider replacing old appliances with new stainless, energy efficient appliances, unless the kitchen needs a complete overhaul. In that case, let the next home owner do it the way they like it. Otherwise, they may just remodel the remodel, as I have done several times. Make sure the landscaping looks neat and tidy. Finally, use a professional stager to bring your house to life and let people know how good it can look.
