If hitting a horseshoe pit with a hand grenade is the desired outcome, then I would say AVMs work just fine.Are you sure the GSE automated appraisal models fell apart?
Who claims that economics is a science? It takes more than just seeming to fit a framework to actually be qualified within any certain framework. There is a really big difference between a social science and a science. It is empirical relevance instead of mathematical rigor which is lacking in economics. Economics lacks testable hypotheses, consensus, and is rife with political overtones.Insofar as Economics is a science, then too is appraising (which is a specialized arm of Economics - predicting human behavior as it relates to the home purchase market).
Adjustments can never be "supported" when 95% of the time the so-called support is really equal to fake news. Put ten appraisers individually (in a vacuum from each other) into a non-homogenous metropolitan area and ask them all to provide "support" for the same subject property GLA adjustment (should be easy right?) or how about a view adjustment while we are at it? We will get ten drastically different addendums "supporting" the adjustments and adjustments that are all over the place. My point is that it does not matter if an appraisal report has addenda that "supports" adjustment opinions, because they are opinions created from other opinions created from culled (using opinions) market data and analyzed using opinionated methods all selected by opinion. The only real meaning to supported or non-supported adjustments comes down to the answer to the question of "Did you try to look at market data for this?" Any form of "Yes" answer = a "supported" adjustment.Of course that's possible. It's also possible that the adjustments aren't supported...
