Great responses below. Also consider:
Invite a Lender to qualify these strangers coming to your home.
Be cheerful and greet each person who walks through the door. Make certain to be genuine and interested in their questions. Have school info handy.
Talk to the buyer. Find out what they are looking for in a home and, if possible, show them why this home could be a good fit for them. Do not be afraid to ask about their concerns about the house and if something specific does not appeal to them.
Make sure the house being shown is exceptionally clean. Declutter areas and put away personal items such as childrenâ€™s drawings. The idea of an open house is for visitors to envision themselves living in your home.
Check the outside of the house for cosmetic flaws. Tidy the yard.
Get all vehicles out of the driveway on the day of the open house, check for available parking on the street.
Open all blinds and drapes allowing natural light to flood the house.
Turn on lamps and make sure all lights in the house are in working order in case a potential customer flips the switch.
Try natural candles with light scents or home baked bread. You may hire a stager http://www.kathytoth.com/custompages_reports.php?key=s193025
