Let the sunshine in. Windows should be clean. Open curtains and draperies and show the buyer how bright and cheerful your home is. For and evening inspection, turn on all your lights. Proper illumination of the house is a welcome sign to a potential buyer.
Minor repairs can make major differences.
Replace all burned-out light bulbs. A dripping water faucet discolors sinks and suggests faulty plumbing. From top to bottom. Show buyers the full value of your attic, basement and other utility spaces by removing all unnecessary articles. Now is a good time to wash the outside of your water heater, change the furnace filter and make sure inspection access is easy.
