I am doing some retro reviews from 2005-2007.
About 1/3 are totally fraudulent.
About 1/2 of the appraisers came from very far away.
About 80% did not verify anything.
80% of the appraisals have no property/neighborhood/market area specific narrative; commentary is canned and could apply to Juno, Alaska or Reno, Nevada, maybe even London, England or Damascus, Syria.
All of the reviews I get have the appraiser listed and they appear to be new folks at the time following their "mentors" guidelines.
The MLS photos are very prevalent.
I have not seen one yet that says anything bad about the subject property. There are NO references to deferred maintenance; there are never any negative property aspects. But then again, there are no property descriptions saying anything positive either.
Most of it is form filling at its best.
