The Three Approaches to Value
The three approaches to value are sales comparison, cost, and income capitalization. Sales comparison adjusts recent comparable sales to the subject, cost adds land value to depreciated improvement cost, and income capitalization divides net operating income by a cap rate. The appraiser then reconciles the results into one final value opinion.
The three approaches to value anchor the valuation and appraisal section of the national exam, where you are asked to match each approach to its methodology and to the property type it best fits.
Three routes to the same destination
Appraisers have three recognized methods for estimating value: the sales comparison approach, the cost approach, and the income capitalization approach. Each looks at the property through a different lens, and each is strongest for a different kind of property. A single appraisal may use more than one of them, then reconcile the results into one final opinion of value.
Sales comparison approach
The sales comparison approach compares the subject property to recently sold comparable properties and makes dollar adjustments to each comparable's sale price to account for differences (location, size, condition, amenities, date of sale). Adjustments are made to the comparable, never to the subject. After adjusting, the appraiser weights the comparables by reliability and settles on a value range. This approach dominates for houses, condominiums, and other properties that sell frequently, because there are plenty of comparable sales to work from.
Cost approach
The cost approach estimates value as land value plus the depreciated cost of the improvements. The appraiser values the land as if vacant, estimates the current cost to build the improvements, subtracts accrued depreciation, and adds the two figures together. It is most reliable for new construction, special purpose buildings (churches, schools, public buildings), and properties that rarely sell, where comparable sales are scarce.
Income capitalization approach
The income capitalization approach values a property by its ability to earn. The appraiser estimates net operating income and divides it by a market derived capitalization rate: Value = NOI divided by Cap Rate. It is the primary approach for income producing property such as apartment buildings, office buildings, and retail centers, where the buyer is really purchasing a stream of income.
Reconciliation
Reconciliation (sometimes called correlation) is the process of weighing the results of the approaches used and arriving at a single value opinion. The appraiser does not simply average the numbers. Instead, the appraiser judges which approach best fits the property type, the quality of the data, and the purpose of the appraisal, then gives the most weight to the most credible result.
| Property type | Best approach |
|---|---|
| Single family home | Sales comparison |
| New or special purpose building | Cost |
| Apartment or office building | Income capitalization |
A concrete example
A bank orders an appraisal of a six unit apartment building. The appraiser runs the income approach by dividing its net operating income by a market cap rate, uses the sales comparison approach on other recent apartment building sales, and checks the cost approach against what it would take to build the building new. All three produce a range. Because the property's value is driven by its rent, the appraiser weights the income approach most heavily and reconciles to a final number near it.
Exam angle
The exam most often asks you to match an approach to its definition or to a property type. Remember the three core formulas and what each approach starts from: sales comparison adjusts comparable sale prices, cost adds land to depreciated improvements, and income divides NOI by the cap rate. Watch for a distractor that describes the cost approach but calls it the sales comparison approach, or that tells you to adjust the subject instead of the comparables.
Memory trick
CSI
The three approaches to value, in order: remember C-S-I.
- C
Cost approach: land value plus depreciated improvement cost, best for new and special purpose buildings
- S
Sales comparison: adjust recent comparable sale prices to the subject; best for homes and condos
- I
Income capitalization: divide net operating income by a cap rate; best for income producing property

How the exam tricks you on this
The classic trap is adjusting the subject property instead of the comparables. In the sales comparison approach, every dollar adjustment is applied to the comparable's sale price to make it resemble the subject, never the other way around. An answer choice that says to adjust the subject is almost always the wrong one.
Two more patterns to watch for:
- Mismatched definitions. The exam will describe one approach but attach the wrong name, for example defining the cost approach while calling it sales comparison. Match the method to its steps, not to the label.
- Wrong property type. Cost is best for new or special purpose buildings, sales comparison for homes, and income for income producing property. Choosing the approach that fits the wrong property type is a common error.

Market Value vs. Market Price
Market value is an appraiser's opinion of the price a property should bring on the open market at a given time, assuming a willing buyer, a willing seller, and no abnormal pressure. Market price is the actual dollar amount a property sold for. When all the conditions for market value are met, the two should match, but they do not always.
Read definitionHighest and Best Use
Highest and best use is the reasonably probable use of a property that produces the greatest value, and it must pass four tests: legally permissible, physically possible, financially feasible, and maximally productive. Appraisers identify it before valuing a property because it sets the standard the valuation measures against.
Read definitionPrinciple of Substitution
The principle of substitution says a buyer will pay no more for a property than the cost of an equally desirable and available substitute. It sets a ceiling on value and underlies all three appraisal approaches, because comparable sales, replacement cost, and market cap rates all measure what a buyer could get elsewhere instead.
Read definitionCapitalization Rate vs. Gross Rent Multiplier
The capitalization rate (cap rate) is a property's net operating income divided by its value, expressing the return an investor earns after operating expenses and vacancy are factored in. The gross rent multiplier (GRM) is simply the sale price divided by gross rent, with no expenses subtracted at all. Cap rate is the more precise, income-approach tool; GRM is a quick, rough screening number.
