Which depreciation method would most likely be utilized in a mass appraisal scenario?

In a mass appraisal scenario, the most widely used method for determining depreciation is the Trended Original Cost approach. This method is particularly effective for assessing a large number of similar properties because it allows appraisers to account for the time value of money and inflation, adjusting the original cost of properties based on market trends and economic conditions.

Trended Original Cost provides a systematic way to estimate the current value of a property by taking its original cost and adjusting it with a trend factor. This approach is efficient for mass appraisals since it can be applied uniformly across a large dataset, ensuring consistency and accuracy in the assessment process. It facilitates comparison between different properties and helps establish a reasonable estimate of depreciation while ensuring that appraisals reflect current market dynamics.

While the Sales Comparison method is useful in certain valuation contexts, it is less suitable for mass appraisal due to the extensive data collection and comparative analysis it requires for each property. Individual Component Analysis focuses on the specific depreciation of components, making it more appropriate for detailed, individual appraisals rather than broader, mass evaluations. Overall Age-Life, while a valid method, tends to oversimplify the complexities of different properties that exist within a larger appraisal context.
