Hire an appraiser to determine the value of your land if you don't have the market knowledge to do it yourself. Without knowing what your land is worth, it will be hard for you to assess the strength of the offers that you receive. The appraisal will also determine the highest and best use of the land, and you can use that information to target your marketing activities.
Your buyer profile can depend on what type of property you are selling, whether the land has been developed already, its location and market conditions, among other criteria. Is your likely buyer an individual looking for a lot for a new home? Or is your buyer going to be a builder or developer looking for land for their next project? Or is your buyer some combination of those, or someone different altogether? There may be different buyers for finished lots, rural acreage or a parcel of suburban land in a thriving new home market.
