Which of the following is NOT a requirement under USPAP regarding comparable sales?

The reason why the choice indicating that an appraiser must analyze all comparable sales regardless of availability is not a requirement under USPAP is that USPAP emphasizes the necessity of using relevant and available comparable sales rather than mandating an exhaustive analysis of all potential comparables.

According to USPAP, appraisers are expected to perform a comparison based on adequate market data that is applicable and pertinent to the property being appraised. This means that while an appraiser should thoroughly analyze comparable sales that are available and relevant, there is no requirement to analyze every single comparables sales in the market, especially those that may not provide constructive and significant information to the appraisal process.

In contrast, it is essential for appraisers to assess current listings to gauge the market's active pricing continuum, consider the sales history of the subject property to understand its performance over time, and evaluate at least three comparable sales to establish a credible opinion of value. Each of these activities aligns with the principles of providing a well-supported market analysis and ensuring that appraisals reflect fair market value.
