Which appraisal report type would provide detailed explanations and supporting data?

The narrative report is designed to provide a comprehensive and detailed appraisal analysis, which includes thorough explanations and supporting data. This type of report typically covers the property's description, the methodology applied in the appraisal process, market analysis, and a discussion of comparable properties. By articulating the reasoning behind the appraised value, the narrative report offers clarity and justification for the conclusions drawn.

This level of detail is particularly beneficial in complex appraisal situations where stakeholders require a more in-depth understanding of the valuation process. It often includes charts, graphs, and other visual aids to enhance clarity and support the appraiser's findings, making it suitable for scenarios where detailed analysis is crucial for decision-making.

In contrast, other report types, such as the executive summary, comparative report, and brief report, provide less detail and context. They may summarize key findings or provide a high-level overview, but they do not delve as deeply into the data or rationale behind the appraiser's valuation as a narrative report does.
