Which type of appraisal report is considered the most comprehensive and complete?

The narrative appraisal report is recognized as the most comprehensive and complete type of appraisal report. It provides a detailed analysis of the subject property and includes extensive information such as property descriptions, market analysis, and data supporting the appraiser's conclusions. Narrative reports are typically used in complex appraisal situations where in-depth explanation and documentation are necessary, such as right-of-way acquisitions, litigation, or when higher-stakes valuations are required.

This type of report allows the appraiser to thoroughly outline the rationale and methodologies used in arriving at the final value estimate, making it particularly valuable for stakeholders who need a deeper understanding of the appraisal process. The narrative format also often combines both quantitative and qualitative analyses, which adds to its depth and utility.

In contrast, summary reports provide a more concise overview, focused only on the main points, while desktop appraisals are based on limited data and typically do not involve physical inspection of the property. Comparative appraisals rely on analyzing similar properties without the detail and justification provided in a narrative report. Thus, the narrative appraisal stands out for its thoroughness and depth of analysis.
