Highest and Best Use
Highest and Best Use is the most profitable legal use of a property that a typical buyer would pay the most for. Assessors use this standard when determining what your property is worth, and it directly impacts your assessment amount.
The key distinction is this: your property's assessed value is based on what it could reasonably be used for, not necessarily how you currently use it. A single-family home on a corner lot near commercial zoning might be assessed as if it were commercial property, even if you're living in it. A farmer's land near a growing city could be assessed for development potential rather than agricultural value. This difference can mean thousands of dollars in annual taxes.
How Assessors Apply It
Assessors evaluate four criteria to determine highest and best use: the use must be physically possible, legally permitted, financially feasible, and generate maximum net income. A rural property may have development potential legally, but if infrastructure costs make development infeasible, that use won't drive the assessment.
When challenging your assessment at a Board of Review hearing, you can argue that the assessor misidentified the highest and best use. Present evidence that:
- Current zoning or deed restrictions prevent the assumed use
- Comparable sales show properties in similar situations sell at lower values than the assessment implies
- Development or conversion costs exceed what buyers would reasonably spend
- Market demand for the assumed use is weak or declining in your area
- Your property's classification doesn't match its actual income-generating potential
Connection to Assessment Methods
The income approach, sales comparison approach, and cost approach all hinge on highest and best use assumptions. If an assessor valued your small retail building using commercial income assumptions but comparable commercial properties sold at 35% lower values per square foot, that signals a highest and best use error. The comparable sales method is your strongest tool here because it shows what actual buyers paid for similar properties.
Assessment ratios matter too. Your state likely aims for an assessment ratio of 33% to 35% of fair market value. If your assessment assumes highest and best use that doesn't exist in your market, the ratio will be artificially high compared to nearby properties with the same zoning.
Common Questions
- Can I argue that my property shouldn't be assessed for a highest and best use I don't plan to pursue? Yes. If highest and best use is speculative or years away, you can present appraisals, market studies, or expert testimony showing the assumed use has no current market value. Bring documented evidence that comparable properties with identical zoning actually sold for less.
- How does property classification interact with highest and best use? Classifications (residential, commercial, agricultural) encode assumptions about highest and best use. If your property is classified wrong, challenge the classification itself. A seasonal residential property shouldn't be classified as full-time residential, and an industrial property shouldn't be treated as standard commercial.
- What evidence should I bring to a Board of Review hearing about this? Bring comparable sales of properties in similar zoning with similar potential uses, appraisals that address highest and best use directly, zoning reports showing development constraints, and economic data showing weak demand for the assumed use. A professional appraisal costs $400-1,200 but is often worth it for properties over $300,000.
