Sometimes they're simply failing to read your report and don't really understand what they're supposed to be doing. A relocation company reviewer for one of my assignments had a checklist item for the sales comparison approach that read, "which comparable did you weight your value to, and why?". I told him that the report contained several pages of market analysis along with listing support, my value was derived from reconciling all the market data provided, and I didn't weight my value to a single comparable in the sales comparison approach. My reasoning & methodology was properly reconciled and thoroughly explained in the report, however this reviewer couldn't see the forest for the trees. Similar to the reviewer concept of "bracketing", he thought that appraisers should automatically identify one sale as the best indication of value, and base their opinion of the "anticipated sales price" solely on it. Makes it easier to review, I suppose, but somewhat disheartening at times to learn what they're used to seeing from your competition.
