You will need to advertise an email address and phone number for people to contact you so you can field additional questions about the property. Most often, people will want to know if the property is free and clear of any liens or encumbrances including back taxes. They will want to know if there are any other closing costs, Home Owner Association Fees and other details regarding the property. Always be direct when dealing with your customers. If you don't know the answer simply say you don't know and that you'll find out or direct them to the appropriate resource. Typically a surveyor or the local county can help them with what they are looking for.
Selling land is usually a more complicated process than selling improved property. When you sell a property with a building, its use and value is established by the building on it. Before buying unimproved land, most buyers want to investigate what they can do with it to determine what it's worth. At the same time, the buyer pool for land is usually smaller than the buyer pool for improved property. With this in mind, selling land quickly requires unique strategies.
After identifying your likely buyers, try to think like them so you can focus your message to convey what they need to know about your property. Have information ready about schools, shopping and other nearby amenities. For developable land you can be prepared with zoning information and insight from local authorities about the location and capacity of water and sewer service. Each property is different, so customize your information for your situation and your targeted buyers.
