For Fort McDowell property, historical valuation depends on evidence that describes the earlier property and the buyer choices available during that period. When arm's-length residential transfers are limited, the report should explain the search, the rights conveyed, and why any broader-market evidence is relevant. The assignment should describe the property and market of the selected period, not simply discount or inflate a current value backward.
Historical valuation should not be a current value pushed backward by a percentage. The assignment needs evidence from the selected period, including the subject's condition, property rights, competitive setting, and the alternatives buyers actually had. For Fort McDowell, the appraisal should consider site utility only when it changes the subject's competitive position.
During the historical period, when arm's-length residential transfers are limited, the report should explain the search, the rights conveyed, and why any broader-market evidence is relevant. The earlier market may require a different comparable pool from the one that would make sense today.
An old sale is not automatically a good historical comparable. The appraiser should understand the transaction, the neighborhood stage, the property's condition, and whether the sale reflected the same residential market during the period being studied.
Archived listings, photographs, permits, recorded documents, subdivision history, and improvement records can materially change the historical comparable set. The strongest record links those documents to market evidence from the same period.
