Valuation & Appraisal

Value, price, and cost are related but distinct. Market value is an economic concept based on buyer-seller expectations in the market. Price is the amount paid in a transaction. Cost is what it takes to produce the improvement.

Value is an estimate under a defined premise and date; market value commonly assumes a typical, informed transaction under stated conditions. Price is the amount actually agreed or paid, which may reflect unusual financing, motivation, or concessions. Cost measures resources spent to acquire land or produce improvements and may differ from both value and price because of depreciation, scarcity, or market demand.

A single sale is evidence, not automatically the market value of every similar property. An appraiser reconciles relevant data and intended-use assumptions; a price can be above or below a supported value conclusion. Always identify which term a problem asks for before selecting its number.

A rational buyer generally will not pay substantially more for a property than the cost of acquiring a reasonably similar substitute, all else equal. Substitution supports the sales comparison and cost approaches to value.

Substitution holds that a prudent buyer generally compares a property with available alternatives offering similar utility and will not pay more than the cost of acquiring an equally desirable substitute, after considering time, inconvenience, and risk. It does not require identical properties; differences are measured and reconciled.

This principle supports comparing sales and, in suitable cases, considering the cost of creating a substitute improvement. Scarcity or a unique location can make close substitutes hard to find, so substitution is a guide to market behavior rather than a mechanical price ceiling. The best evidence is a substitute a market participant could actually acquire.

The value of a component is measured by what its presence adds to the whole, not by its cost. An improvement may cost more than the value it contributes.

Contribution measures a feature's effect on the value of the whole property, not the feature's standalone cost. An improvement is economically worthwhile only if the value it adds is commensurate with its cost under the owner's objective and market conditions. A costly upgrade can be over-improvement for its neighborhood.

The principle also explains why a modest feature can add substantial value in a market that strongly wants it, while an expensive feature may add little. Analyze buyer reaction and comparable evidence rather than assuming replacement cost transfers dollar-for-dollar into market value.

Progression: a lower-value property benefits from proximity to higher-value properties. Regression: a higher-value property is adversely affected by proximity to lower-value properties.

Progression describes a lower-value property gaining support from nearby higher-value properties; regression describes a higher-value property being pulled downward by nearby lower-value properties. These effects are relative to the subject's surroundings and are not automatic dollar adjustments without evidence.

Neighborhood context can influence buyer expectations, utility, and marketability. A property may be atypical in either direction, but the analyst still needs to examine comparable transactions and relevant external factors rather than assume a fixed percentage for progression or regression.

Highest and best use is the legally permissible, physically possible, financially feasible, and maximally productive use of a property. The HBU of the site as vacant may differ from the HBU as improved.

Highest and best use is the reasonably probable use that is legally permissible, physically possible, financially feasible, and maximally productive. Each test matters: zoning and private restrictions address legal permissibility; site size and access address physical possibility; market-supported income or value addresses feasibility; and the final test selects the use that produces the greatest value among feasible alternatives.

Analyze the site as though vacant and as currently improved. An existing building may be continued, altered, or removed if another use is legally allowed, physically possible, feasible, and more productive. “Most profitable” alone is not enough if required entitlements cannot reasonably be obtained or the site cannot support the use.

The sales comparison approach estimates value by comparing the subject with reasonably similar properties that sold, adjusting for relevant differences. Adjustments go to the comparable, not the subject.

The sales comparison approach estimates a subject's value from comparable properties that have sold, adjusted for material differences in property rights, financing, conditions of sale, market timing, location, physical characteristics, and other relevant factors. Select evidence for similarity and reliability, not just proximity.

Adjustments are made to the comparable sale to indicate what it might have sold for if it had the subject's relevant characteristics. If the comparable is inferior, add to its sale price; if superior, subtract. Reconcile the adjusted indications rather than taking an unexamined average.

If the comparable has a superior feature, adjust the comparable downward. If the comparable has an inferior feature, adjust the comparable upward. The adjustment brings the comparable to parity with the subject.

Adjustment direction follows one question: what would this comparable have sold for if it had the subject's feature? A superior comparable feature is removed with a negative adjustment; an inferior feature is added with a positive adjustment. This direction applies whether the difference is a garage, view, condition, or another supported market factor.

An adjustment is not simply the cost of installing a feature. Use paired sales, market extraction, or other support to estimate contributory value, and avoid double-counting a condition already reflected in the sale. The adjusted comparable is a counterfactual indication, not a literal changed transaction.

The cost approach estimates land value plus the depreciated value of improvements. Value = Land Value + (Replacement/Reproduction Cost − Accrued Depreciation). Most useful for new or special-purpose properties.

The cost approach estimates land value as though vacant plus the current cost to reproduce or replace improvements, less accrued depreciation: value ≈ land value + improvement cost − depreciation. Replacement cost reflects a modern equivalent with similar utility; reproduction cost seeks a duplicate. The selected cost basis should match the problem.

This approach is often useful for newer construction or special-purpose improvements when cost and depreciation can be estimated, but it does not make market value identical to construction expense. Land must be valued separately because it is not depreciated in this calculation. Taxes, entrepreneurial incentive, and other components may be treated according to the appraisal problem's specified framework.

Physical deterioration is loss in value from wear, damage, age, or deferred maintenance. It may be curable (economically worth repairing) or incurable (not worth curing).

Physical deterioration is loss caused by wear, damage, age, or deferred maintenance. Curable deterioration is economically feasible to fix when the resulting value gain justifies the cure cost; incurable deterioration is not economically practical to cure, even if a physical repair is possible.

The cure test is economic, not merely technical. A leaking fixture might be straightforward and worthwhile to repair, while replacing a short-lived component near the end of its life may be treated differently depending on cost and remaining utility. Document the condition and avoid assuming all old components have the same depreciation.

Functional obsolescence arises from features within the property that are inadequate, outdated, or superfluous relative to current market standards. A floor plan that buyers reject is a classic example.

Functional obsolescence stems from an inadequacy, poor design, or superadequacy within the property relative to current market expectations. Examples include an awkward floor plan, too few bathrooms for the market segment, or an oversized feature whose cost is not supported by buyer demand.

The issue is internal to the improvement, even if the relevant market standard changes over time. It may be curable when a feasible alteration creates enough value, or incurable when correction is impractical or uneconomic. Distinguish it from physical wear and from external influences such as noise or nearby land uses.

External obsolescence arises from influences outside the property, such as adverse nearby uses or broader economic conditions, and is often difficult for the owner to cure.

External obsolescence is a value loss caused by influences outside the subject property, such as a nearby nuisance, adverse traffic pattern, or broader market shift. The owner often cannot remove the source, which makes the loss commonly incurable, but that characterization should not be treated as a rule that every external influence is literally impossible to mitigate.

Measure the market effect rather than assume it. A new road can be harmful or beneficial depending on access and noise; an economic downturn may affect a whole area but recover over time. The defining distinction is that the source is external to the property, not the duration or size of the impact.

A capitalization rate expresses the relationship between a property's NOI and value. Higher cap rates generally correspond to lower values for the same NOI, all else equal. Cap Rate = NOI ÷ Value.

A capitalization rate relates one period's stabilized net operating income to value: cap rate = NOI ÷ value. Rearranging gives value = NOI ÷ cap rate and NOI = value × cap rate. The rate is expressed as a decimal in calculations, and the income period and value date should correspond.

A cap rate is not an interest rate, mortgage rate, or total return. It is a direct-capitalization relationship based on market evidence and a stabilized income estimate; it excludes financing and investor-specific tax effects in the basic model. Higher rates imply lower indicated values for the same NOI, all else equal.

GRM relates sale price to gross monthly rent. GRM = Sale Price ÷ Gross Monthly Rent. Estimated Value = Subject Rent × Market GRM. GRM does not account for operating expenses.

Gross rent multiplier (GRM) is sale price divided by gross rent for the same period. A monthly GRM uses monthly rent; an annual GRM uses annual rent. Estimated value equals the subject's gross rent for that same period multiplied by a market-derived GRM. Consistent period units are essential because annual and monthly multipliers differ by a factor of twelve.

GRM is a quick comparison tool, not an income capitalization rate. It ignores vacancy, collection loss, operating expenses, capital items, and financing; two properties with identical rent can have different net income and value. Use comparable properties from a relevant market and period, and avoid presenting the estimate as a complete income analysis.

A comparative market analysis (CMA) is a brokerage pricing tool and is not automatically an appraisal. Brokers must avoid representing a CMA as an independent appraisal when it is not.

A comparative market analysis (CMA) is a broker's pricing analysis prepared within brokerage practice. It can use comparable sales, listings, and market context to help a client make a pricing decision, but it is not automatically an appraisal or an independent appraiser's opinion developed under appraisal standards.

The scope, intended use, assumptions, and professional role matter. A licensee should accurately identify the work and avoid implying credentials, independence, or compliance with appraisal standards that do not apply. A CMA can be useful without being mislabeled; a formal appraisal may be appropriate when a client or lender needs an appraisal for a defined use.

In simplified exam problems, depreciation may be stated as an amount or percentage. Read whether the question asks for total depreciation, depreciated improvement value, or overall property value.

In simplified problems, depreciation may be stated as a dollar amount, a percentage of improvement cost, or a rate per year. Determine the base before applying it: land is generally separate, while accrued depreciation reduces improvement value. Then read whether the question asks for depreciation itself, depreciated improvement value, or total property indication.

Depreciation in appraisal means loss in value, not necessarily accounting depreciation or tax basis. A stated straight-line calculation may be appropriate for an exam exercise, but real appraisal depreciation can reflect physical, functional, and external causes and need not follow a simple age-life schedule.
