Why the Purchase Price and Appraised Value May Be Different

A practical look at contract prices, market value, land transactions, and what happens when the numbers do not match

The Problem With a Contract Signed Years Ago

This situation is especially common with development land. A land transaction can remain under contract for a long period because the buyer may need time to work through rezoning, density approvals, utility availability, access, environmental matters, site-plan review, permitting, financing, and other due-diligence items before closing.

The important point is that the purchase price may have been negotiated under one set of market conditions, while the appraisal is completed years later under another. The appraiser is typically developing an opinion of market value as of the appraisal's effective date, not simply recreating the market that existed when the contract was first signed.

During that period, a great deal can change. Comparable land prices may rise or fall. Construction costs and financing costs may change. New competing projects may enter the market. Infrastructure may improve. A rezoning request may be approved, modified, delayed, or denied. The supply of developable land may also change.

The contract price does not automatically move with the market. It remains the price negotiated between that particular buyer and seller, subject to the terms of their agreement. By the time the property is appraised, however, current market evidence may support a different value.

That does not automatically mean the contract is unreasonable. It means the appraiser has to understand the transaction: when the price was negotiated, what the parties knew at the time, what contingencies or approvals were contemplated, whether the agreement was amended, and whether the transaction reflects motivations that would be typical of the broader market.

In other words, the contract is an important piece of market evidence, but it is not a substitute for market analysis.

A Simple Example: Assemblage

Imagine a developer already owns a commercial site and is negotiating to acquire the vacant parcel next door. By itself, the neighboring parcel may have a market value of approximately $2.0 million. However, acquiring it would allow the developer to combine the two properties, improve access, increase site efficiency, or create a larger development opportunity that would not otherwise be available.

The developer may therefore agree to pay $2.5 million. That additional $500,000 may make perfect economic sense to that specific buyer because of the value created by the assemblage. But the same premium may not be recognized by a typical purchaser evaluating the parcel on a stand-alone basis.

This is one of the clearest examples of why a purchase price and market value can differ. The purchase price reflects the circumstances of a specific transaction. Market value asks what the property would most probably sell for under the assumptions contained in the applicable definition of market value.

How Does an Appraiser Test the Contract Price?

Comparable sales remain a major part of the analysis, but land can be particularly challenging because truly comparable transactions may be limited. Two sites that appear similar in acreage can differ significantly in zoning, density, access, utilities, flood conditions, entitlement status, development timing, location, and highest and best use.

For that reason, an experienced appraiser does not simply compare the contract price with one or two nearby land sales and stop there. The transaction should be tested from several perspectives.

• How does the contract price compare with other sales on a price-per-acre or price-per-square-foot basis?

• Are there sales with similar zoning, density, utility availability, access, entitlement status, and development potential?

• What was known or reasonably anticipated when the contract was originally negotiated?

• Have market conditions changed materially since the contract date?

• Does the proposed development reasonably support the land basis being paid?

• What return would a typical developer or investor require at that land cost?

• Are buyers in the market paying similar premiums for comparable development opportunities?

• Is part of the purchase price attributable to a benefit that is unique to this particular buyer?

• Have the contract terms changed through amendments, extensions, deposits, options, or other negotiated provisions?

The appraiser then reconciles those pieces of evidence and determines what they indicate about the property's market value as of the effective date. The goal is not to prove that the contract price is right or wrong. The goal is to understand what the transaction represents and how much weight it deserves within the overall valuation.

What About Future Rezoning and Development Potential?

Development land often trades based partly on expectations about the future. A buyer may agree to a higher price because they expect a rezoning, greater density, utility extensions, a future road improvement, or another change that could increase the property's development potential.

Those expectations may be reasonable and may absolutely influence market behavior.

However, an appraiser has to distinguish between what is legally permissible and physically possible as of the effective date, what is reasonably probable, and what remains speculative.

For example, if a rezoning has not yet been approved, the appraiser should not automatically value the property as though the approval already exists. Instead, the appraiser should analyze the probability of the change, the evidence supporting that expectation, the timing and cost involved, and whether typical market participants are paying for that potential.

Assignment conditions also matter. When an uncertain condition is assumed to be true for purposes of the analysis and that assumption could affect the assignment results, an extraordinary assumption may be appropriate. If the appraisal is performed as though a condition exists that is contrary to known fact, a hypothetical condition may be required. In either case, the condition should be clearly identified and its relevance to the value conclusion explained.

This distinction is important because development potential can have real market value, but not every proposed use or anticipated approval has the same probability of occurring.

Why Doesn't the Appraiser Just Match the Contract Price?

If a buyer has agreed to pay $4.0 million, it is understandable that the buyer, seller, broker, and other parties involved in the transaction may hope the appraisal also supports $4.0 million. But confirming the contract price is not the purpose of an independent appraisal.

The appraiser's responsibility is to develop an independent opinion of value based on the relevant market evidence, the property's characteristics, the applicable definition of value, and the assignment conditions.

If the available evidence supports $3.5 million rather than $4.0 million, the report should explain why. Conversely, if the market evidence supports the contract price, the appraisal should demonstrate that support through its analysis.

If every appraisal simply matched the price written in the contract, regardless of the comparable sales, income potential, development economics, market conditions, or circumstances surrounding the transaction, there would be little purpose in obtaining an independent appraisal.

That does not mean appraisers are always correct. An appraisal can contain errors. Relevant sales may have been overlooked. Adjustments may not be adequately supported. Important property information may have been missing. An assumption may no longer be appropriate. New information can legitimately change an analysis.

The key is the nature of the challenge. A productive reconsideration might say, “Here is additional market evidence that was not considered, and here is why it may affect the analysis.” That is very different from saying, “The value needs to be higher because the contract price is $4.0 million.”

A credible appraisal should be able to withstand reasonable questions about its methodology, data, assumptions, and conclusions.

When the Numbers Don't Match

When the purchase price and appraised market value do not match, the first question should not be, “Who is wrong?” The better question is, “Why are they different?”

• The contract may have been negotiated several years earlier and the market may have changed.

• The buyer may be paying a premium because the property completes an assemblage.

• The transaction may reflect a strategic benefit that is unique to that buyer.

• The purchase price may have been based on an anticipated rezoning, density, or development approval that has not yet occurred.

• The property may have development potential that is not fully reflected in the most obvious comparable sales.

• The contract may contain unusual financing, concessions, contingencies, or other terms that affect the stated price.

• Or the purchase price may simply be above or below what current market evidence supports.

The purchase price matters. It is real transaction evidence and should be analyzed carefully. But it tells us what one buyer agreed to pay one seller under the circumstances of that particular deal. It does not, by itself, establish what the broader market supports.

A well-supported appraisal should help the reader understand that distinction. Its purpose is not merely to validate a deal. It is to explain the market evidence and provide a credible opinion of value as of a specific date.

Final Thoughts

Differences between contract price and appraised value are not unusual, particularly in commercial real estate and development land. The reasons can range from changing market conditions to buyer-specific motivations, assemblage value, future development expectations, or simply a contract price that is not supported by current market evidence.

Understanding the reason for the difference is far more useful than focusing only on the gap between the two numbers.
