Can anyone please clearly define what "underwriter request" is legitimate and part of "clarification" of the appraisal and what is NOT legitimate and outside the scope of work. I have had occasion (one currently) where the "Underwriter" (for the bank or the mortgage insurance company?) has requested an "appraisal revision" in which I am asked to add an addendum and complete the cost approach for a detached condo (on the condo form). From my perspective, this is outside the appraisal scope of work, not my area of expertise and essentially the lender's attempt to have me do additional workm2: so they can close the loan. I have put the request back to their appraisal department for direction, but what IS and what IS NOT my responsibility is unclear. Is the appraiser required to do endless revisions each time a different UW looks at the appraisal? AM I required to comply with "requests" from the mortgage insurance company? My mortgage broker friends are unclear about this...as am I.
