Move your emotional attachment to the home to the back seat. This house has great memories; but, you are moving on with a new home. If it has wallpaper, take it down and paint neutral. If it has non neutral carpeting, get it replaced. Spruce the home up and make it salable. If you had a used car for sale, wouldn't you get the car cleaned inside and out and place a nice FOR SALE sign on it? You need to treat your home the same way.
