In practice, arms-length verification is part of evaluating what aspect of data quality?

• A. The property’s environmental risk
• B. Source integrity, reliability of the sale data
• C. The municipal budget
• D. The distance to downtown

Answer: (B)

Arms-length verification is about the trustworthiness of the data you’re using. It checks that the sale data come from a legitimate, independent transaction where the buyer and seller acted in their own best interests under market conditions, with no related parties or pressure influencing the price. This directly evaluates the integrity and reliability of the sale data, ensuring the comparables reflect true market behavior rather than biased or manipulated results.

Environmental risk, municipal budget, or distance to downtown aren’t about whether the sale data are credible or from a reliable source, so they aren’t the focus of arms-length verification. Those factors belong to other parts of the appraisal process (risk factors, municipal analysis, or location/market area considerations), rather than the quality and integrity of the sale information itself.
