Which data source is explicitly identified as secondary data in the material?

• A. Local MLS data
• B. Chamber of Commerce data
• C. County deed records
• D. Appraiser's own field notes

Answer: (B)

In the Sales Comparison Approach, data sources are divided into primary data (collected directly by the appraiser for the assignment) and secondary data (collected by others and used for background context). The Chamber of Commerce data is the one explicitly identified as secondary in the material because it comes from a third party and provides general business and economic context about the area, not property-specific details gathered by the appraiser.

Local MLS data, while often third-party and useful for market activity, is not the one labeled as secondary in this material, and the appraiser’s own field notes are primary data since they’re collected directly by the appraiser for the assignment. County deed records are public records and typically considered secondary data in many contexts, but the prompt points to the Chamber of Commerce data as the explicitly labeled secondary source.
