In which situation is the sales comparison approach least applicable?

The sales comparison approach is a method used in property appraisal that relies on comparing the subject property to similar properties that have recently sold in the same area. This approach is most effective when there is a good selection of comparable properties to analyze, as it allows the appraiser to make reliable adjustments based on differences between the properties.

In scenarios where there are few comparable properties available, the effectiveness of the sales comparison approach diminishes. The lack of suitable comparables means there might not be sufficient data to accurately evaluate the market value of the subject property. Without enough recent and relevant sales to analyze, making appropriate adjustments becomes challenging, which can lead to less reliable and potentially inaccurate appraisals.

Conversely, when there are numerous comparables or when the market is stable and predictable, the sales comparison approach becomes quite robust and yields reliable results. A highly populated area often features more transactions and a more diverse range of comparable properties, further enhancing the validity of this approach.
