Effective Age
Definition and meaning of Effective Age in real estate.
Effective age is an appraiser's estimate of a building's age based on its current physical condition, wear and tear, and utility, rather than its actual chronological age.
In more detail
A property that has been exceptionally well-maintained or remodeled will have an effective age that is lower than the number of years since it was built. Conversely, a house that has suffered from neglect or deferred maintenance will have an effective age that exceeds its chronological age.
Real estate appraisers use this concept to calculate physical depreciation and establish a property's current market value. For buyers and lenders, understanding effective age helps determine how much life remains in key structural elements and systems before they need replacement.
