Get as much information as you can obtain ahead of time. Check the tax records for current sales. Be realistic (this is where some friends may be able to help you see your house from a prospective buyer's point of view). Pricing your house correctly will help it sell in a reasonable amount of time. If you hold an open house, ask for feedback from people who come to see your home. Did you interview any real estate agents, and were they willing to give you a price range?
