Highest and Best Use: The Foundation Beneath Every Value Conclusion

The Four Tests of Highest and Best Use

Highest and best use is defined as the reasonably probable use of a property that is legally permissible, physically possible, financially feasible, and maximally productive. A use that fails any one of these four tests cannot be considered the property’s highest and best use, regardless of its profitability in isolation.

As Vacant vs. As Improved

Appraisers typically analyze highest and best use both as if the site were vacant and as currently improved. These two conclusions can differ meaningfully — a property with an underutilized structure on a redevelopment-ready parcel, for example, may have a highest and best use as vacant that differs from its use as improved, which has direct implications for value.

Why It Drives Comparable Selection

Comparable sales are only meaningful when they share a similar highest and best use with the subject property. Two parcels with identical acreage and zoning can carry very different values if their realistic development potential differs — which is why highest and best use analysis precedes, and shapes, comparable selection.

Common Misconceptions

A property’s current use is not automatically its highest and best use, and zoning alone does not settle the question — appraisers also weigh the probability of a zoning change, market demand, and development feasibility before reaching a conclusion.
