A commercial property can be well located, fully occupied, and still be underperforming its potential. When owners, investors, or lenders ask, “what is highest best use?” they are asking a more consequential question: What legally allowable, physically possible, financially feasible use will produce the greatest value for this site or property?

Highest and best use is a foundational real estate valuation concept, but it is also a practical decision framework. It helps determine whether a property should remain as it is, be repositioned, redeveloped, held for future use, or acquired for a different purpose. For commercial decision-makers, the answer can shape sale timing, capital planning, lease strategy, site selection, and long-term return on investment.

What Is Highest and Best Use?

Highest and best use is the reasonably probable and legal use of vacant land or an improved property that is physically possible, appropriately supported by the market, financially feasible, and results in the highest value.

The phrase is often misunderstood as meaning the use that generates the highest gross revenue. That is not necessarily correct. A use may produce substantial revenue while requiring excessive construction cost, carrying greater vacancy risk, or generating an inadequate return on capital. The highest and best use is the use that creates the strongest supported value after accounting for market demand, development costs, operating costs, timing, and risk.

For an existing building, the current use may already be the highest and best use. A well-designed medical office building near a hospital, for example, may have greater value as a medical asset than as a redevelopment site, even if the land could legally support a more intensive project. The analysis is not an automatic argument for demolition or new construction. It is a disciplined test of the alternatives.

The Four Tests of Highest and Best Use

A credible highest and best use conclusion follows a sequence. Each test narrows the field of realistic alternatives. Skipping a test can lead to an attractive concept on paper that does not work in the market or cannot be permitted.

• Legally permissible: The proposed use must comply with zoning, deed restrictions, building codes, environmental requirements, access regulations, and other applicable controls. A use that would require rezoning or a special approval may still be considered, but only when that approval is reasonably probable.

• Physically possible: The site must be capable of supporting the use. Size, shape, topography, utilities, drainage, traffic access, visibility, parking, floodplain conditions, and environmental constraints all matter. A corner parcel may appear suitable for retail until access limitations or required parking reduce the usable building area.

• Financially feasible: A legally permissible and physically possible use must also produce a return sufficient to justify the investment. This requires analysis of rental rates, sale prices, absorption, construction costs, financing, operating expenses, tenant improvements, and investor return requirements.

• Maximally productive: Of the feasible alternatives, the highest and best use is the one that generates the greatest residual land value or overall property value. This final test compares realistic options, not every theoretical development concept.

These tests are interconnected. Strong demographics cannot overcome a lack of utility capacity. Permitted density has limited value if demand cannot support the additional space. The most productive use is determined by the combined evidence, not by a single favorable factor.

Vacant Land and Improved Property Require Different Analysis

Highest and best use is commonly considered in two ways: as though a site were vacant, and as currently improved.

The vacant-land analysis asks what a buyer would develop on the site if it were available for its highest value purpose. This is particularly relevant for development land, redevelopment corridors, excess land around an operating facility, and acquisition decisions. An investor evaluating a former industrial tract, for instance, may compare continued industrial use with warehouse development, flex space, retail conversion, or a mixed-use plan where zoning and demand support those alternatives.

The as-improved analysis considers the existing building and site improvements. It asks whether the current improvements contribute more value than they cost, whether they should be renovated, or whether removal and redevelopment would be justified. An older office building on a high-traffic commercial corridor may still be viable if renovation costs are controlled and there is durable demand for smaller professional suites. If the building has functional obsolescence, high maintenance costs, and weak leasing prospects, redevelopment may be the better value conclusion.

This distinction matters because land value alone does not dictate the right course. Demolishing a functioning asset can destroy value when replacement costs, entitlement risk, and lost income exceed the value of the proposed new use.

Why Highest and Best Use Matters to Commercial Owners

Owners often encounter this issue before a sale, refinancing, estate planning event, redevelopment decision, or major capital expenditure. The analysis can clarify whether to market a property to owner-users, investors, developers, or a more specialized buyer pool.

Consider a retail property with declining occupancy. The immediate reaction may be to reduce rents and pursue replacement tenants. Yet the more valuable question may be whether the parcel’s access, surrounding growth, and zoning support a different use, such as medical office, service retail, self-storage, or a small industrial development. Conversely, a property that appears ready for redevelopment may be more valuable after targeted lease-up and operating improvements.

For corporate users, highest and best use also affects occupancy cost. A company may own a large site that exceeds its long-term operational needs. If a portion of the property can be subdivided and sold, ground leased, or developed without compromising operations, the excess land can become a source of capital rather than a passive carrying cost.

In the Madison and Jackson-area market, these decisions frequently depend on location-specific factors: traffic patterns, municipal planning, hospital or institutional proximity, utility availability, industrial access, and the depth of demand for a particular property type. Broad market assumptions are not enough. The relevant submarket and buyer profile must support the conclusion.

Highest and Best Use Is Not a Guarantee of Development

A highest and best use conclusion identifies the use that produces the strongest supported value at a particular point in time. It does not require an owner to act immediately. Market conditions, financing availability, tenant commitments, tax implications, and the owner’s investment horizon can all support a decision to hold.

Timing is often the central trade-off. A parcel may have a future redevelopment use that is more valuable than its current use, but the market may not yet support near-term construction. In that case, maintaining income from the existing property while preserving future development flexibility may be the sounder strategy.

Risk also matters. A development pro forma can look compelling when based on aggressive rent growth, rapid lease-up, and favorable construction pricing. A disciplined analysis tests those assumptions against comparable transactions, competing supply, likely absorption, and contingency requirements. The highest projected value is not always the most credible value.

How Appraisal and Advisory Work Together

Appraisers use highest and best use analysis to support opinions of market value. Their conclusions must be grounded in evidence available as of the appraisal’s effective date, including market activity, land sales, zoning, physical characteristics, and economic conditions.

Advisory work can take the analysis further by evaluating ownership objectives and execution alternatives. That may include a disposition strategy, site-selection analysis, redevelopment feasibility, lease restructuring, acquisition underwriting, or portfolio planning. The valuation question is, “What is the property worth?” The strategic question is, “What should the owner do with it?” The two should inform each other, but they are not identical.

For example, a property may appraise at a value that supports continued ownership, while the owner may still choose to sell because the capital can earn a better risk-adjusted return elsewhere. Similarly, an owner may retain a lower-yielding property because it is essential to operations or provides expansion capacity. Real estate is a business asset, and the right decision must fit both the property and the owner’s broader capital strategy.

Applying the Analysis Before You Commit Capital

Before purchasing land, renovating an aging building, extending a major lease, or placing a property on the market, owners should test the property’s probable highest and best use. Start with the facts that cannot be negotiated: title restrictions, zoning, access, utilities, site condition, and building functionality. Then evaluate what the local market will actually support, not simply what has succeeded in another city or in a prior market cycle.

The strongest decisions come from comparing realistic alternatives with consistent assumptions about cost, timing, income, and risk. A disciplined highest and best use analysis does more than assign a label to a property. It gives owners a clearer basis for protecting capital, reducing avoidable costs, and acting when the market supports the next move.
