3.1 The Concept of Value and Economic Principles

Value, Price, and Cost

Three words are constantly confused on the exam, and the test deliberately tries to trip you up. Keep them separate:

• Value is the present worth of future benefits arising from ownership. It is an opinion, estimated as of a specific date.
• Price is the amount actually paid in a completed transaction. Price is historical fact.
• Cost is the total expenditure to create the improvement (labor, materials, soft costs). Cost does not necessarily equal value.

A classic trap: an owner spends $60,000 on a custom indoor pool, but the home's value rises only $15,000. The cost was $60,000; the contribution to value was $15,000. Cost and value diverged because the market did not demand that feature.

The Four Characteristics of Value (DUST)

For any property to have value in the market, four elements must be present. Memorize the acronym DUST:

A frequent exam question: "Which characteristic is missing when air, though useful, has no market value?" The answer is scarcity. Demand requires both the wish to buy and the financial ability to do so, sometimes called effective demand.

Types of Value

The same property can carry several different values at once. The exam wants you to distinguish them:

• Market value — most probable price a property should bring in a competitive, open market under an arm's-length sale.
• Investment value — worth to a specific investor based on their goals; may exceed market value.
• Insurable value — replacement/reconstruction cost of improvements only (land is not insured).
• Assessed value — set by a tax assessor to calculate property tax; often a fraction of market value.
• Liquidation value — price under forced or hurried sale; typically below market value.

Market value rests on four assumptions: a willing buyer and willing seller, both reasonably informed, no undue pressure on either party, and a reasonable exposure time on the open market.

Economic Principles That Drive Value

Appraisal logic is built on recurring economic principles. Expect direct definition questions:

• Substitution — a buyer will pay no more for a property than the cost of an equally desirable substitute. This is the foundation of all three appraisal approaches.
• Highest and best use — the legally permissible, physically possible, financially feasible, and maximally productive use that yields the greatest value. Land is always valued at its highest and best use, even if currently improved otherwise.
• Supply and demand — when supply rises faster than demand, prices fall; when demand outpaces supply, prices rise.
• Conformity — maximum value is achieved when properties are similar in style and use to surrounding properties.
• Anticipation — value is created by the expectation of future benefits (e.g., a planned transit station nearby).
• Contribution — a component's value equals what it adds to the whole, not its cost (the pool example).

Progression, Regression, and Change

Two related corollaries of conformity are heavily tested:

• Progression — a modest home gains value from being among larger, higher-priced homes nearby.
• Regression — a large, over-improved home loses value when surrounded by smaller, lower-priced homes.

The principle of change reminds appraisers that no physical or economic condition stays constant; markets move through four phases: growth, stability, decline, and revitalization. The principle of increasing and diminishing returns states that improvements add value only up to a point; beyond it, added cost no longer raises value (over-improvement).

Two more principles round out the set. Plottage is the increase in value created when two or more adjoining parcels are combined under single ownership into one larger, more useful tract; the act of combining them is assemblage. A developer who assembles four small lots into a single buildable site may create plottage value greater than the sum of the individual lots. Finally, the principle of competition holds that excess profit in a market attracts competitors, which over time tends to reduce that profit and stabilize value.

Highest and Best Use in Depth

Because highest and best use (HBU) drives every appraisal, expect a question that tests the four screens in order. A use qualifies only if it passes ALL four, applied sequentially:

1. Legally permissible — zoning, deed restrictions, and environmental rules allow it.
2. Physically possible — the site's size, shape, soil, and access support it.
3. Financially feasible — the use generates enough income or value to justify the cost.
4. Maximally productive — among the feasible uses, it yields the greatest value.

Worked scenario: a vacant downtown lot could hold a parking lot (legal, possible, feasible, modest return) or a mixed-use building (also legal and feasible, far higher return). The mixed-use building is the highest and best use because it is maximally productive. A use that is enormously profitable but illegal under current zoning is not the HBU unless a variance or rezoning is reasonably probable. Note that HBU is always tested for the land as though vacant and again as improved — an existing building can become an 'interim use' if the land's HBU has shifted to something else.
