Research Comp Data: Selection of Comps
• Geographically closer is better
• Same neighborhood or similar neighborhood
• Same “market area” – may be quite broad
• Physically similar is better
• Size & design, Lot size, Age, etc.
• Most recent sales better, possible values change w/time
• Residential 6-18 mos., commercial 2-3 years • Time on market - within reasonable range
