Which term is associated with the method of assessing a large number of properties simultaneously?

The term associated with the method of assessing a large number of properties simultaneously is mass appraisal. This approach is typically used by municipalities and large assessment jurisdictions to evaluate property values in an efficient manner, ensuring that the assessments are uniform and equitable across similar types of properties.

Mass appraisal employs statistical techniques and data analysis to estimate the value of all properties within a certain area at the same time, as opposed to individual appraisals which examine properties one by one. This method is especially useful for tax purposes and allows for a more streamlined process in updating property values in a jurisdiction.

Other options present concepts related to property assessment but do not accurately describe the large-scale, simultaneous approach that mass appraisal entails.
