Engineering Breakdown method measures depreciation based on what factor?

The Engineering Breakdown method for measuring depreciation is centered on analyzing each individual component of a property. This approach involves assessing the cost and expected life of various building elements, such as the foundation, roofing, plumbing, and electrical systems. By focusing on these specific components, appraisers can provide a more precise measure of depreciation since it considers how well each part of the property is functioning and how long it is expected to last before needing repairs or replacement.

This method allows for a detailed understanding of where value loss occurs within the property over time, leading to a clearer picture of the overall depreciation. In contrast, the other options do not focus on this detailed analysis of individual components, making them less suitable for accurately measuring depreciation in a nuanced way.
