WRT AMC involvement in this debate I think that's pretty obvious; and equally obvious that it is in their economic interests to obtain a nominally "acceptable" skillset for the lowest possible price.
I can also acknowledge that fact as a reason many incumbent appraisers will oppose any reduction in qualifications criteria as it relates to the most difficult and most expensive barrier to entry for aspiring appraisers to negotiate.
But if that's the primary rationale the AQB wants to respond to then I want them to be honest about it and acknowledge it openly. If you've got the hair to act in your own self-interests then say it loud and say it proud, don't hide behind a combination of untruths and half-truths and ancillary reasons as cover for your real priorities.
I still think the AQB would do well to follow the appraisal process in their deliberations, particularly when as that process stipulates that problem identification comes first, before we start deciding which modes of analysis are necessary to get to a supported conclusion.
