We have had this discussion many times before.
Your whole argument is Desaix became a good appraiser and he didn't have a degree. You are looking at it at an individual person level and not looking at it at the level of the profession. It's just not a serious profession without a degree requirement.
Just the fact that half of the appraisers think appraisal is a trade rather than financial services is absurd.
It should be the same as accounting. Degree which includes about a year of related coursework, licensing exam, an no experience requirements.
DeSaix is just one example who everyone here knows and respects. That's the only reason why I cite him. It wouldn't resonate with anyone for me to cite the (literally) dozens of others I have known over the years. Which BTW has also included several of our regulars, both past and present. Not to mention the others who I've read reports from over the years without knowing what their academic educations were. Heck, the Chief Appraiser at the commercial bank I worked for never completed a 2yr or 4yr degree, and their did my supervisor when I first relocated to their San Diego office. That doesn't mean they were incapable of competently appraising the properties that lender was doing mortgages on; which on average were far more complex appraisal problems than the tract homes being sent through the GSEs.
If you think the purpose of [state regulation of licensees] is to elevate the social status of the profession then that's an opinion a lot of people share. OTOH if the purpose of establishing the minimum criteria @ the govt level is to identify the minimum level of intellectual performance it takes to competently perform an SR1/SR2 appraisal report to the minimum specs then the answer to that question might be a little different.
I don't even want to get into the rent-seeking aspect of using the levers of govt to protect the incumbents which also appears in many of these conversations (albeit not this one, so far). Reasonable people disagree, but I personally don't consider that a legitimate function of govt.
I'm not anti-college by any means, just like I'm not anti-designation from the AI or other professional orgs. And sure, I have personally benefitted greatly over the years as a result of holding and using my education (in general) and my CG (specifically). Which I earned after spending several years specializing in SFR appraising.
My accountant has a Masters degree in Accounting. His rates are the same as every other accountant in town and so is his performance on my returns. He might be more qualified than others on certain types of assignments, but there's plenty of the less complicated work out there for the others to service. Heck, a lot of people get by with TurboTax instead of using an EA or CPA. .
