Which of the following is not a component of the mass appraisal system?

In a mass appraisal system, components are systematically structured to assess property values efficiently and accurately across a larger scale. Data collection is essential as it involves gathering comprehensive information about the properties being assessed, including attributes such as size, location, age, and condition. Model application refers to the implementation of statistical models to determine property values based on the collected data and established methodologies. Exploratory data analysis is a critical step in understanding the relationships and trends within the data before applying models, allowing appraisers to assess the quality of the data and identify any anomalies or patterns.

Market sales analysis, while important, primarily serves the purpose of understanding actual sales trends and influences on property values, rather than being a direct component of the mass appraisal process itself. This component usually supports the other aspects, such as data collection and model validation, but it does not constitute a necessity within the mass appraisal framework. Instead, it provides context and supplementary insight that helps inform the appraisal but does not directly operate as part of the mass appraisal system’s foundational components.
