Economic Life
The period during which a property or building improvement contributes value and generates income that exceeds its operating costs. Unlike physical life, economic life ends when the property becomes unprofitable to operate or maintain, even if it's still structurally sound.
Example
“Although the 50-year-old office building was structurally sound, its economic life was ending due to outdated technology infrastructure that made it less competitive in the market.”
Memory Tip
Think of it as the property's "earning life" - how long it can economically contribute value before it becomes more of a financial burden than benefit.
Why It Matters
Investors and appraisers use economic life estimates to determine property values, calculate depreciation, and make decisions about renovations or demolition. Understanding economic life helps buyers assess long-term investment potential.
Common Misconception
Economic life and physical life are the same thing, but a building may be physically sound yet economically obsolete due to changing market conditions or technology.
In Practice
An old shopping mall might be structurally intact but reach the end of its economic life due to online shopping trends, making demolition and redevelopment more profitable than continued operation. Appraisers consider economic life when valuing income-producing properties for mortgage lending.
Etymology
This appraisal term emerged in the early 20th century as economists began applying lifecycle concepts to real estate, distinguishing between physical deterioration and economic obsolescence.
