First, you need to understand the exact dimensions of the parcel of land you are evaluating. Next, call the local zoning department and ask them what the designated building setbacks are for the property in question (building setback requirements are very common, and are imposed as a way of giving order and consistency to the buildings in any given area). When you take these setbacks and regulations into account (relative to the size of this parcel of land), is there still enough room to build something worthwhile – or does it render the property useless? I've come across several properties that were designed (albeit, unintentionally) to be too small and after factoring in the setbacks – you can't build anything on them at all, leaving them virtually worthless!
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.
