What should I do to make the property show better?
First, make your house look as clean and spacious as possible. Remember, people may look behind your doors — closet and crawlspace doors, as well as those to the bedrooms and bathrooms. So get rid of all the clutter; rent a storage space if you need to, hold a garage sale or call a local charity.
After you've cleaned, try to correct any cosmetic flaws you've noticed. Paint rooms that need it, re-grout tile walls and floors, remove or replace any worn-out carpets. Replace dated faucets, light fixtures, and the handles and knobs on your kitchen.
