Every condemnation or tax reduction case will generally require a real estate appraiser. But very often, additional experts will be necessary depending on the issues presented in the case.

As is the case with a real estate appraiser, the additional experts can make or break the case. The marked difference in a condemnation and tax certiorari case is that there are two distinct valuation models. In a tax assessment case, the property is valued as it is, while in condemnation the property must be valued based on its highest and best use regardless of actual use. And, in the determination of a highest and best use, a property owner may show a reasonable probability of rezoning. This means one must retain a zoning expert. It cannot be left to the real estate appraiser. Typically, a land planner, zoning attorney or architect will be utilized.
