Which of the following is NOT one of the three types of appraisal reports?

The correct choice is the summary report, which is not one of the three primary types of appraisal reports used in real estate valuation. The three main types of appraisal reports are typically categorized based on the methods used to determine property value: the direct comparison report, the cost approach report, and the income approach report.

1. The direct comparison report involves analyzing comparable properties that have recently sold in order to estimate the value of the subject property based on market conditions.

2. The cost approach report calculates the value of a property based on the cost to replace or reproduce the improvements, minus any depreciation.

3. The income approach report focuses on the income generated by the property, primarily used for investment properties, determining value based on potential earnings.

In contrast, a summary report typically condenses information and findings from a more detailed report and is not categorized as a standalone appraisal methodology. Therefore, it does not represent one of the three key approaches that appraisers employ to ascertain property value.
