Comparable Sale Adjustment (Proper Sequence)
Adjusts a comparable sale price in the standard appraisal sequence, transactional adjustments first (financing, then market conditions) and property adjustments after (location, physical, nonrealty), with percentage adjustments compounding. Inputs are the comparable sale price, each adjustment amount or percentage, and the months since the sale.
