Assuming that appraisers / valuers are acting professionally the writer sees the two most significant problems within our industry as: 1. Lack of multi-discipline training 2. Lack of application training Yes, I am on a crusade to enhance our current lack of multi-disciplinary training. However, this essay treats the latter, being the egregious misapplication of appraisal methodology and/or value concepts to an appraisal / valuation problem. Yes, USPAP has taken us deeper into professionalism by requiring enhanced statements relating to the appraisal problem, scope of service, intended use and user, reporting, and so on. But we need to go further. Even professionals, acting as they believe they should, too often err in their solving of the appraisal problem by applying the incorrect value concept and/or the wrong level (accuracy requirement and reporting) to the assignment. Cure: We need cross-discipline appraisal / valuation training.  And before or after, or currently with cross- discipline training, we need appraisal / valuation cross-discipline application training. Areas to cover would be: 1. Insurance 2. Eminent domain 3. Purchase price allocations 4. Cost segregation 5. Fair value accounting 6. Transfer pricing 7. And so on It’s time for us to get going on this.
