When selling land without a realtor you will need to do several things to be successful. First place a for sale by owner sign on the property with contact information. You may want to put signs up along busy roadways as well so that your sign is seen by the largest number of people. If you land is in a popular tourist location then you may want to advertise it in papers outside of your state where most visitors come from. I have seen people list land on craig’s list as well. Sometimes contacting the people who own the land right next to yours to see if they are interested in buying is successful as well.
