The Age-Life method is primarily used for what purpose in property appraisal?

The Age-Life method is primarily used for determining depreciation, which is a critical aspect of property appraisal. This method assesses the effective age of a property compared to its total economic life to estimate how much value a property has lost over time due to wear and tear, obsolescence, or other factors.

In this approach, an appraiser evaluates the physical condition of the property and its age to calculate the depreciation percentage. This percentage is then applied to the property’s replacement cost to determine the property's current value after accounting for depreciation.

By using this method, appraisers can provide a more accurate representation of a property’s worth, reflecting its current state rather than just its original cost or market conditions. It effectively integrates the aspect of time into the assessment of value, which is essential in understanding the real impact of age on property value.

Other choices, such as estimating market demand, calculating land value, or estimating replacement costs, do not align with the primary purpose of the Age-Life method. Instead, they focus on different aspects of appraisal that require separate methods or analyses.
