Any reasonably objective history of the appraisal profession would - IMO - at least argue that licensing was a significant part of its decline, if not its death knell. When a state issued license became the single most imporant credential for an appraiser, professional appraisers started their losing battle trying to defend their profession - someone's License #12345 was deemed all the evidence a client needed to satisfy regulatory requirements, and those letters appended after an appraiser's name - SRA, IFA, RM and all ther rest - became irrelevant for most residential work.
