What are the methods used for measuring depreciation in property appraisal?

The correct answer is based on the methods that specifically relate to measuring depreciation in property appraisal. The capitalization of income method is significant because it not only assesses the income generated by a property but also reflects how depreciation affects that income stream. As properties age or face obsolescence, their ability to generate income may decline, leading appraisers to consider depreciation as a crucial factor in determining value.

While the sales comparison method can provide insight into a property's value relative to similar properties, it does not directly measure depreciation itself. Instead, it relies more on market trends and comparable sales data. Therefore, while it has relevance in overall property appraisal, it doesn't explicitly focus on depreciation.

Options involving direct costs or other methodologies do not directly correlate with the intuitive measures needed for assessing depreciation in property appraisal. The accuracy of measuring depreciation through these methods is important for appraising properties effectively, especially when emphasizing how depreciation directly affects potential income, making it a vital concept for appraisers to understand.
