Which action is least likely to be considered prohibited conduct towards an appraiser?

The action of asking an appraiser to correct the address listed on an appraisal report is least likely to be considered prohibited conduct. This request pertains to factual information that is critical for the accuracy and validity of the appraisal report. Ensuring that the address is correct is essential, as it directly affects the property being appraised, and it's within the lender or mortgage originator's rights to request correction of factual errors on the report.

In contrast, requesting an appraisal revision could imply seeking changes based on subjective judgment, and asking for adjustments in the value suggests an effort to influence the appraiser's opinion. Inquiring about the timeline for appraisal completion, while typically harmless, might be viewed as pressuring the appraiser unnecessarily. These actions may raise ethical concerns about the influence of the lender on the appraisal process, potentially violating regulations designed to maintain the independence of appraisers.
