......Who determines the degrees? I mean these are not black and white judgments in many cases. Shades of gray.
Terrel, in my "former life", I was one of a few independent contractor investigators who performed field investigations, and communicated the results, to my state's appraiser regulatory agency.
If NO ONE is to determine what might be "shades of gray" vs. what is "black & white", then why bother with even attempting to regulate appraisers?
Some appraisals are pure garbage (aka, very misleading)...some are not.
Some appraisers are clueless and some are not.
Some appraisers are very careless, and some are not.
You ask what might be "unsubstantiated land value?"; perhaps, the appraiser stating that the site value for the Subject was estimated via the extraction method...but having no support for this in the workfile.
And, to your question regarding the appraiser's disclosure of the inclusion of a HC and/or EA in an appraisal...and the implications of same: would you be surprised that at least some appraisers, IF they even understand what a HC or EA is, provide absolutely NO comment whatsover that "their use might have affected the assignment results"?
Bottom-line, we're discussing things in the abstract here. But, give either one of us a really "bad" report of an appraisal for our review, I'll bet that in the end we'll both be able to say "what a load of garbage!"
