Your agent should prepare a flyer that displays a photo and provides details about your house. There should also be a phone number so buyers can contact your agent to get additional information. The flyers should be displayed in a prominent location in your home and also in a brochure box attached to the "for sale" sign.
The brochure box is convenient for those buyers who drive by and just happen to see the "for sale" sign in front of your house. It provides enough information so they can determine if they want to follow up with a phone call or inform their own agent they are interested in your house.
