What are the three approaches to value, and when should each be used?

Valuation & Market Analysis on the Real Estate Exam

Professional appraisers use these three approaches as the foundation of appraisal practice. Understanding which approach is most appropriate for different property types is essential for real estate professionals. Exam questions frequently test your ability to identify which approach an appraiser would use in specific scenarios. Knowing the strengths and limitations of each approach helps you advise clients on valuation credibility and understand appraisal reports.

Understanding Valuation & Market Analysis: Key Concepts

What It Means

The Sales Comparison Approach (also called Market Data Approach) estimates value by comparing the subject property to recent sales of similar properties in the same market. The appraiser selects comparable properties that are similar in location, size, condition, and features; adjusts for differences in characteristics like square footage, age, or amenities; and arrives at an estimated value. This approach is most reliable when many recent, comparable sales exist in the market. It is the preferred method for single-family residential properties, condominiums, and vacant land. The appraiser must be skilled in selecting truly comparable properties and making appropriate adjustments; if comparables are too dissimilar or markets are inactive, the approach becomes less reliable.

The Cost Approach estimates value by summing the land value plus the reproduction or replacement cost of all improvements, minus accrued depreciation. The appraiser first determines the land value (often by comparing recent sales of similar vacant land), then estimates the cost to build the structure new, then deducts depreciation caused by physical deterioration, functional obsolescence, or external obsolescence. This approach works well for new construction where actual costs are known, for special-use properties with few comparables (such as churches, schools, or government buildings), and for income-producing properties where the other approaches may be less reliable. The cost approach is generally less reliable for older properties where accurate depreciation estimates are difficult.

The Income Capitalization Approach (also called Income Approach) estimates value by converting the property's net operating income into a value using a capitalization rate. The appraiser calculates the property's annual net operating income (gross rental income minus operating expenses), then divides by an appropriate capitalization rate to arrive at value. The formula is: Value = Net Operating Income / Capitalization Rate. This approach is essential for investment properties, apartment buildings, commercial buildings, and other income-producing properties. The strength of this approach is that it directly reflects the property's income-generating potential. The limitation is that accurate income and expense data can be difficult to obtain, and selecting the appropriate capitalization rate requires market knowledge.

Appraisers typically use all three approaches when conducting a formal appraisal, then reconcile the three value estimates to arrive at a final opinion of value. The weight given to each approach depends on the property type and data availability. For a single-family home, the sales comparison approach typically carries the most weight. For a commercial office building, the income approach typically carries the most weight. The final appraisal report shows how all three approaches contributed to the final value conclusion.
