Mike Ford, Samuel Miller and Mike Kennedy - these are common names and I don't really know much about these individuals. I would guess they are just running appraisal firms and speakers that appear at conferences.
Jermy Bagott is an MAI and A-GRS with many years of experience.
Cindy Chance does NOT have a track record as an appraiser, nor any Designations or Licenses - from looking at LinkedIn. She did graduate with a BA from Oxford in philosophy and economics - and a Ph.D. from Georgetown in Philosophy. Only if you think Appraisal is all about Ethics - would you give much weight to that. Choosing her as CEO under the assumption that she could delegate all the technical work to people under her is absolutely INSANE. Those ****ers are all incompetent. None of them have what it takes make good decisions and move forward. They should have hired somebody with a Ph.D. in Applied Statistics and Mathematics from a top tier university in the US, - with experience and knowledge of real estate appraisal. But they are so screwed up, the entire profession is so screwed up ---> This would and will never happen any time soon.
In general your comment doesn't make a lot of sense. That's OK, it's kind of standard for most residential appraisers on this forum. There are different levels of appraisers, and most appraisers have IQs in the 95-115 range, - not high at all. The MAI's have IQ's that generally max out around 125+/-, but they do make good use of what smarts they have, for what it is worth. And 80-90% of the time, that is good enough for commercial - as long as you can live with commercial appraisals that are on average 80-85% accurate (per third sources).
If you want an appraiser that you can be sure is accurate in estimating market value for residential real estate in California, like 98+% accurate ---> you will have to search far and wide. That kind of accuracy takes knowledge of advanced math and programming. It is going to be like trying to find a needle in a haystack. Because if you know statistics, data mining, - and can program, you can make 3-4+ times more working somewhere else.
If you want to be an appraiser for GSE appraisals - that is low ****. HS degree will work fine, provided you have the credentials and can follow GSE guidelines good enough for the AMCs. It is an average IQ job.
