How does USPAP instruct an appraiser to calculate a discount when valuing multiple items in a single assignment?

When valuing multiple items in a single assignment, USPAP does not provide specific instructions on how to calculate discounts. The guidance within USPAP leaves room for appraisers to utilize their professional judgment and expertise in determining the most appropriate approach for their particular valuation scenario. Each assignment can be unique, and the context, types of items being appraised, and market conditions can significantly influence the methodology an appraiser chooses.

The absence of explicit instructions means that appraisers are expected to assess the specifics of their assignment and may apply different strategies or methods as they see fit. This flexibility allows for tailoring the valuation to reflect the nuances of the items and the marketplace, rather than adhering to a one-size-fits-all approach.
