(1)  Start with the CEILING.  Crazy, but a ceiling will make a room sparkle!  We did this with a listing, as the owner was short of money, and it sold.  (2)  Avoid loud colors.  Go to a paint store and see what is popular there.  No red dining rooms now.  (3)  Change front door if necessary.  (4)  Clean the bathrooms WELL,  (5)  Be sure all lights in and out are working as they should, to make the property bright and cheery.  THIS IS JUST A BEGINNING, BUT ELBOW GREASE CAN WORK WELL in selling the home.
