I have been tap dancing around this, but I am just going to say it. Any argument that appraisers' inspections are inherently superior would be quickly defeated by any "power user" that wanted to. Anyone who does any volume could almost certainly produce appraisal reports discrediting the inspection process being performed today by the so-called "trained" appraisers you refer to. Just think about the reports you personally review. How many times does the sketch not even match the photos?
Or, look at state board complaints. See how many examples you find of homes not being measured correctly, critical items being omitted, condition being misreported, external factors being ignored, etc. When FHA reports appraisers a huge percentage of the time it is due to inspection-related matters.
You have to remember that not all in the appraisal pool are as good as you.
I am not raising these issues to pave the way for anything. I just want to show the logical fallacy so appraisers with valid concerns don't get shot down as simply trying to protect their own incomes. My views on "hybrids" are certainly not a driving factor to those who are pushing this now.
