Value Concepts and Principles

Value is what a property should be worth to a typical buyer, price is what it actually sold for, and cost is what it took to build. The most tested distinction is progression versus regression: a modest house gains value among finer homes, and a fine house loses value among modest ones.
Why this matters
Exam writers describe a neighborhood scene and ask which economic principle is at work, and licensees who blur value, price, and cost misprice listings.
The college version
In normal terms
- Value is an estimate of worth; price is a fact from one sale; cost is the money spent building, and the three often differ.
- One parcel can carry several values at once: market, assessed, appraised, investment, insurable, liquidation, and plottage.
- The economic principles explain why value moves, from highest and best use and substitution through progression, regression, and change.
Concepts in this outline
- Value versus price versus cost — value is an opinion of worth; price is the actual sale amount; cost is what building or improving required.
- Market value — the most probable price an informed, unpressured buyer and seller would agree on in an open market.
- Assessed value — the value a tax assessor assigns for calculating property taxes; may differ from market value.
- Appraised value — an appraiser's supported opinion of value as of a specific date, produced through the appraisal process (see Topic 03).
- Investment value — what a property is worth to one particular investor given that investor's own goals and finances.
- Insurable value — the value of the destructible improvements for insurance purposes, excluding the land, which cannot burn.
- Liquidation value — the price expected when a property must sell quickly, typically below market value.
- Plottage value — the added value created when adjacent parcels are combined into one more useful whole.
- Assemblage value — the value gained through combining adjacent parcels; assemblage is the process, plottage is the resulting increase.
- Highest and best use — the legal, physically possible, financially feasible use that produces the greatest value for the land.
- Substitution — a buyer pays no more than the cost of an equally desirable substitute; the foundation of the sales comparison approach.
- Anticipation — value today reflects the benefits, income, or gains a buyer expects to receive in the future.
- Supply and demand — scarce supply with strong demand raises values; excess supply or weak demand pushes values down.
- Conformity — value is maximized when a property is reasonably similar in size, style, and use to those around it.
- Contribution — an improvement is worth what it adds to total value, which may be more or less than its cost.
- Increasing and decreasing returns — improvements raise value faster than cost only up to a point; beyond it each dollar returns less.
- Balance — value peaks when land, labor, capital, and management are in proportion and land uses complement one another.
- Progression — a lower quality property gains value from being surrounded by higher quality properties.
- Regression — a higher quality property loses value from being surrounded by lower quality properties.
- Competition — profits attract competitors, and new similar supply reduces the excess profits that drew them.
- Change — values are never fixed; physical, economic, social, and governmental forces shift them, so appraisals carry an effective date.
Eli explains
The same idea, in plain words
Explain it like I’m 10
Imagine three numbers written on one house. What a smart, unhurried buyer should pay today is value. What somebody actually paid last month, maybe too much in a rush, is price. What the builder spent on land, lumber, and labor is cost. These can be very different, and only value is an opinion.
Value also depends on who is asking. The tax assessor, the insurer, an investor, and a bank forced to sell fast each see a different number.
Behind every value sit economic principles. The biggest is highest and best use: the legal, physically possible, financially feasible, and most productive use of the land. Substitution says nobody pays more for a house than for an equally good one nearby. Progression and regression say a house is pulled toward the level of its neighbors. Contribution says a feature is worth only what it adds, not what it cost.
Worked example
Dana lists a modest Cape Cod on a Montclair street lined with restored Victorians. The owner spent heavily improving it, but the market cares what similar homes fetch, so substitution sets the ceiling. Because the neighbors are grander, progression lifts Dana's Cape above what it would bring on a street of identical Capes. The owner's brand-new pool, which cost a fortune, adds far less than it cost, showing contribution. A buyer pays a little over the appraised value because two other offers arrived the same day, and that final number is the price, not the value.
