Guess what? - having all the upgrades in the world means diddly squat if you have a cluttered home. Buying a home is sort of like test-driving a new car. When a potential prospect walks through your property, if they are serious, they are mentally placing their own furniture and possessions into what might become their new property.
If your home is over-run with "stuff" they cannot do this! You also need to depersonalize by removing lots of family photos from the walls. A clean, spare spartan look always wins over the heavily decorated look and costs nothing!
