Which of the following is NOT an indirect method of estimating depreciation?

To grasp why the chosen answer is correct, it is essential to recognize how indirect methods of estimating depreciation are defined. Indirect methods typically analyze different aspects of property value and condition rather than relying solely on physical depreciation.

The Overall (Age/Life) method, although widely used in valuation, falls into a direct estimation approach. This method calculates depreciation by comparing the effective age of a property to its expected lifespan, directly assessing how age affects value.

In contrast, the Sales Comparison approach evaluates similar properties that have sold recently to infer value, effectively estimating depreciation as a byproduct of these comparisons. Capitalization of Income focuses on the income-generating potential of a property, translating future income into present value and indirectly assessing how market conditions and management may influence depreciation. Meanwhile, the Engineering Breakdown method involves a detailed analysis of all components of a property to determine their individual depreciations and is also indirect.

Thus, Overall (Age/Life) stands out as a direct method because it straightforwardly uses the property's age and life expectancy to estimate depreciation, while the other methods utilize market or income data to derive an indirect estimation.
