Effective Age vs Actual Age

by | Mar 25, 2026 | Residential Appraisal Insights

Effective Age vs Actual Age We all know the “year built” on a property, but in appraisal, we also consider effective age. A home built in 1980 may “feel” like a 2005 property if it’s been fully remodeled. On the flip side, a 10-year-old home with no maintenance could appear like a 25-year-old one. Effective age impacts depreciation and the cost approach, but more importantly, it reflects how buyers perceive condition. If updates lower the effective age, the home will likely compete with newer comps in the market. I analyze not only the updates completed, but also the quality and how recently they were done. For agents: when marketing a property, be specific about the updates and their timing. “Kitchen remodeled in 2022 with quartz counters and new cabinetry” will often help me justify a lower effective age in the report, which can positively impact value.
