One limitation of Automated Comparable Sales Analysis is:

The correct answer highlights that one limitation of Automated Comparable Sales Analysis is its potential for generating values that are inconsistent or "choppy." This inconsistency arises because the analysis relies on available sales data that can vary in quality and relevance. If the comparable sales data points reflect limited transactions or a diverse range of property conditions, the resulting valuation may lack smoothness or reliability. Consequently, these fluctuating values can lead to substantial discrepancies when assessing properties in varying market conditions, making it challenging for appraisers to arrive at uniform values.

In contrast, the notion that values are consistent and straightforward is not accurate, as the method can yield skewed results depending on data quality. Similarly, relying on a single equation does not consider the nuances of different property types or market fluctuations, which could lead to less accurate valuations. Finally, while using many variables can complicate the analysis, it is often necessary to capture the complexities of real estate markets; thus, this option doesn't correctly identify a limitation of Automated Comparable Sales Analysis.
