What condition allows for the exclusion of a sale from the sales ratio study in South Dakota due to a change in use?

The correct answer highlights that a change in use must result in an increase or decrease of assessed value by at least 10% for the sale to be excluded from the sales ratio study. This threshold is established to ensure that only significant changes in property use—which can have a substantial impact on market valuation—are considered for exclusion.

When a property undergoes a change in use, such as converting from residential to commercial use or changing the type of agricultural use, it can drastically alter its value. The 10% threshold is a means of ensuring that minor changes do not skew the overall sales ratio, thus maintaining the integrity of the assessment data used for appraisals and property tax calculations.

Other potential thresholds or reporting requirements, like a 5% change or a specific time frame for reporting changes, may not align with the standards set for the exclusion criteria, thereby not being sufficiently impactful to justify exclusion from the analysis. Verifying the change by a state appraiser, while important in the assessment process, does not serve as a standalone reason for exclusion based on the magnitude of assessed value change.
