Have someone available to answer the phone when a buyer calls, or at least have an answering machine message with some details on your home prepared. Return calls promptly and courteously. Be reasonable with showing times. Many buyers work during the day, and will only be able to view your home in the evening or on weekends. Have flyers detailing the features of your home, including room dimensions, handy.
Photos keep the home fresh in the minds of buyers when they go home.
Keep track of who views your home and follow up with them after they leave. Purchasing a Home Warranty adds value to your home. Many buyers view FSBO's as desperate, unable to afford the services of a Realtor, and will make offers with this in mind. Have your attorney ready to accept a deposit and prepare a contract. While a Realtor will do this for you, negotiating by yourself puts you at a disadvantage.
