In which situation would an appraiser conduct a desk review?

Conducting a desk review primarily involves verifying appraisal accuracy without necessitating a physical inspection of the property. This process typically entails analyzing the appraisal report, including the methodologies used, the data applied, and the conclusions reached, all based on documentation and available information rather than a site visit. Desk reviews are valuable for ensuring that the appraisal follows established guidelines and standards, and they can help identify potential issues or errors that might affect the appraisal's reliability.

In contrast, evaluating new construction properties typically requires on-site inspections to assess the current condition of the property and verify that it aligns with the plans and specifications. Comparing estimated values with recent market sales would likewise require detailed analysis but generally involves market data rather than solely relying on existing appraisals. Assessing market trends over multiple years usually needs comprehensive analysis of various data points over a significant duration, which cannot be achieved solely through a desk review focused on a singular appraisal’s accuracy.
