For Glendale property, historical valuation depends on evidence that describes the earlier property and the buyer choices available during that period. In established neighborhoods, remodeling, additions, carport or garage changes, pools, landscaping, and effective age can produce larger differences than a simple year-built adjustment suggests. The earlier period should be treated as its own market rather than viewed through today's completed development and remodeled housing stock.
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 Glendale, the appraisal should consider condition only when it changes the subject's competitive position.
For the earlier ownership or market period, in established neighborhoods, remodeling, additions, carport or garage changes, pools, landscaping, and effective age can produce larger differences than a simple year-built adjustment suggests. Period-specific records and sales are more useful than present-day assumptions when this characteristic changed over time.
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.
