What is the primary focus of the cost approach to appraisal?

The primary focus of the cost approach to appraisal is on replacement cost estimation. This approach assesses the value of a property by determining the cost to replace or reproduce the asset at current prices, minus any depreciation that the property may have incurred. Essentially, it centers on the idea that a prudent buyer would not pay more for a property than the cost to construct a similar one from scratch.

In applying this method, appraisers consider the current market conditions to calculate what it would cost to replace the property, whether through new construction or buying similar materials and structures. This makes the cost approach particularly useful for properties that do not frequently sell, or for unique properties where comparable sales data might be limited.

The other options, while relevant in the broader context of property appraisal, do not accurately reflect the central tenet of the cost approach. Market value estimation relates more to the income approach or the sales comparison approach, where actual market conditions and potential revenue generation are evaluated.
