The cost approach estimates value by looking at land value plus the cost to replace or reproduce the improvements, adjusted for depreciation.
The cost approach estimates property value by looking at land value plus the cost to replace or reproduce the improvements, adjusted for depreciation.
The cost approach matters because some properties are not best understood only through recent comparable sales. Newer, unusual, or special-purpose properties can require a different valuation lens.
It also matters because borrowers sometimes assume every appraisal number comes directly from nearby sales. In practice, appraisers can use multiple approaches and weigh them differently depending on the property.
Borrowers encounter the cost approach within the appraisal report when the appraiser decides it is relevant to supporting the value conclusion.
The term becomes practical when the property is newer, unique, or not well served by a simple comps-only analysis.
A newly built home has limited directly comparable recent sales, so the appraiser estimates land value, adds the cost to build the improvements, and adjusts for depreciation. That is the cost approach.
The cost approach differs from the Sales Comparison Approach because it focuses on replacement or reproduction cost rather than relying mainly on recent sale comparisons.
It also differs from the Income Approach, which centers on the earning power of a property rather than its land-and-improvement cost structure.
