The problem with AMCs is that they get paid directly by lenders who get to pick and choose AMCs. So, the lenders exert decisive power over the AMCs. The AMCs, while they do act as a kind of limited "transmission" between the lenders and appraisers, are really just an extension of the lenders will power. They simply provide outsourcing of appraisal staffing duties - they find contract appraisers for the lenders. As an appraiser I much prefer the good old days when there were hundreds of mortgage brokers, banks and lenders at my doorstep. If one got burned because I killed their deal, there was always another one around the corner with a new order. From my perspective, I could live with it. AMCs introduce a big problem, they are a bit different in being so direct about hitting a target, but if you don't play ball, I imagine they simply cut you off. The real problem is that there are so few, you can't afford to turn your back on too many. That's ugly. You know, I have been testing the waters over the last three months, and can firmly say that with respect to AMCs, fees are lower than they were 10 years ago. $350 for a 1004 for a condo in SF, with of all things warnings about complying with umpteen regulations, rating, reporting and so on. The order was snapped up fairly quickly (there was a button to accept or reject - but I never made it to reject ...). Even large $4M home appraisals are getting snapped up for rather low fees. ... All most lenders need is a rubber stamp they could get from RedFin, in most cases, - except for regulations they have to contend with. The system is very messed for anyone who takes appraisal seriously.
As far as paying for a respectable "transmission" or interface between lenders and appraisers, the lenders would have to pay for it. It would take a lot of political pressure to do that. But, there is too much money on the lending side to expect the leaders in the appraisal establishment to do anything about this. Their nose follows the lead of the financial institutions. They are a haven of good paying jobs and opportunities. Politically, you could never expect anything from the Trump organization, the Republican leadership or even worse the very corrupt Democratic leadership.
Many say, that appraisals for home lending are not that valuable because credit ratings and personal information are another more useful kind of collateral. So, perhaps hybrid appraisals are all that is required.
But, getting back to appraisers, serious appraisers, i.e. those who take doing accurate appraisals seriously as a profession, there are other types of appraisal that are more interesting. As you can see on this forum, many are moving away from doing appraisals for typical lenders.
Appraisals and valuations for advanced decision making is probably a new developing field to watch out for. This is where decision makers need accurate information, such as ANSI/BOMA measurements, home "health" data, accurate market pricing models and so on. I don't know that such appraisers have to be all that familiar with advanced statistics, such as Bayesian Statistics and non-parametric statistics, but it certainly wouldn't hurt.
