The highest and best use should be determined before data collection begins, so the appraisal is guided by a specific, legally permissible, physically possible, financially feasible, and maximally productive use from the outset. Establishing the HBU early frames what data are needed and which market factors to analyze, ensuring that every step of the appraisal supports that chosen use. If you wait until after data collection or after final value, you risk collecting irrelevant information or misapplying analyses to a use that wasn’t chosen, wasting time and potentially biasing the conclusions.
