Cost Approach
The cost approach is an appraisal method that estimates property value by calculating what it would cost to rebuild the structure from scratch, then adding the land value and subtracting depreciation. This approach assumes a knowledgeable buyer wouldn't pay more for a property than the cost of building an equivalent structure.
Example
“Using the cost approach, the appraiser calculated the home's value by adding the land cost to the current construction cost of building an identical house, minus depreciation.”
Memory Tip
Think 'construction calculator' - if it costs X to build new, then subtract wear-and-tear to find what the existing property is worth.
Why It Matters
This approach is particularly useful for unique properties, new construction, or insurance purposes where comparable sales are limited. It helps establish baseline property values and is often required for lending and insurance decisions.
Common Misconception
Many think the cost approach always produces the most accurate value, but it's often less reliable for older properties or in markets where land values fluctuate significantly.
In Practice
An appraiser values a custom home by calculating $150 per square foot construction cost for the 2,000 square foot house ($300,000), adding $100,000 for land value, then subtracting $25,000 for depreciation, arriving at a $375,000 valuation.
Etymology
This appraisal term emerged from construction economics, based on the logical principle that a property's value shouldn't exceed what it would cost to build the same thing from scratch.
