To mitigate errors in adjustments when using the paired sales technique, appraisers should:

• A. Extend the search to include only the most recent sale
• B. Validate adjustments with internal notes
• C. Examine several pairs of sales
• D. Apply a fixed adjustment to all properties

Answer: (C)

Using multiple paired sales provides several data points to isolate the impact of a specific attribute, which helps reduce the chance that an error in any one comparison will throw off the adjustment. When you compare more than one pair, you can look for consistency in how the attribute affects price across transactions, spot and discard outliers, and often average the adjustments to arrive at a more reliable value. This makes the paired sales approach less sensitive to idiosyncrasies in a single sale and improves overall accuracy.

Relying on just the most recent sale narrows the data set and can introduce timing or market-specific biases, rather than reducing error. Documenting adjustments is good practice but doesn’t by itself improve the accuracy of the adjustment calculations. Applying a fixed adjustment to all properties ignores real differences in attributes and would distort values.
