George, without analyzing every facet of your posts, it appears you are in favor of a lot of fast click data automated programs, with the appraiser becoming more of a data technician as opposed to being a market expert.
Other than speed, or supposedly freeing up an appraiser to spend more time on analysis (which it won't, since analyzing more data takes more time), other than the efficiency aspec, which is debatable, what about this approach makes it "Better?"
More data does not equate to better data. In fact, sometimes it has the opposite result. The more distance, or further back in time, or broader in scope a data search goes, the less similar to the subject the data becomes, and the less reliable it becomes, and the less relevant to the problem at hand.
Charts and graphs and large regional or time span data searches and statistical outputs look impressive, and can track large trends, beyond that, they are full of innacuracies and can create misleading results . I don't have time to type out all the reasons why, but they are myriad.
I am lost as to why you advocate this approach, unless you want to destroy the validity of appraisers and substitute technical anaylists for them. A tech analyist is faster at data gathering and more computer savvy, so at some point, they would supplant appraisers in your model, with perhaps licensed realtors doing a drive by inspection.
AVM models, with all the tech anaylists working on them for over two decades, and all the data fed into them through multiple sources are still extremely unreliable and so off in value they are only good for extremely low LTV loans or mass portfolio review or the like.
Bradford Technology Comp Cruncher and CVR report has been field and application tested by a number of appraisers on the forum, none of them said it was any better than traditional appraisal model, and not any faster to use. The CVR is an infinite cash cow for the software company though, at a fee for usage of $25 per CVR report upload, each and every time, forever, even after an appraiser has bought the software.
We see a lot of companies pushing these supposed solutions, the "wave of the future programs," which have not proven any more reliable, and are often less reliable or credible as far as actual results. These computer driven programs are money makers though for software companies and enable lenders or AMC's to have more control of the data. Keep in mind that the people pushing these products have a money making and control agenda at stake, and are not introducing these "wave of the future programs" to benefit anyone other than themselves (though their professionally prepared copywriting may convince you otherwise)
