Aside from unknown property condition, which can be resolved through a property inspection. One of the biggest issues that negatively affects AVMs is the inaccuracy of public record/property assessor data in some areas. In the future, that may be much less of an issue and AVM's may be become a much larger threat to take business away from appraisers than today.The killer app for enabling the AVMs will be when some title company or third party database company uses a team of "raters" to go out and do a driveby inspection of every property that gets listed in the MLS; reads the listing, and then rates that property against a specific rating scale. Then if/when the property does enter into contract or does sell later on, a clerk can make phone calls to "verify" the terms and enter that info into the database. And this can all be done using semi-skilled unlicensed technician types, not licensed appraisers.
So what? It still won't be an appraisal. If at some point the lenders convince regulators this is a better system, have at it.... even without regulators, I don't' see how any prudent investor in loans would prefer this, or what it would do to interest rates. I don't even see a big cost savings (especially since the consumer pays for the appraisal).
It costs to hire teams of unlicensed technician types and property inspectors and property raters and then correlate the info and produce estimates , and it assumes a lot of reliability of the info coming from these unlicensed technical types. (whoever they are, they won't have much vested in this...if they are low wage people what do they care if info is correct or not, and what training will they have to know the difference?. (Maintaining and updating databases is expensive and time consuming. I don't see much cost savings, or superior results, but there are always entrepreneurs trying to make money so efforts in this direction will continue.
However, don't kid yourself about the possible acceptance of AVM's by investors in the future. As someone in the secondary market I can tell you for a fact that many investors and in the secondary market have a general distrust of the value estimates produced by appraisers - there is a general perception that there is an overall upward bias in appraisals (even after the bubble), and believe that most adjustments are not based upon sound statistical analysis of market reaction, but are either just a wild guess or, at best, are usually based on inadequate analysis. And these investors do have a point - Let's face it, using a paired sales analysis to derive adjustments is dubious fat best from a statistical perspective, yet this is how most residential appraisers claim to derive most adjustments when what is really needed to derive a an accurate estimate of market reaction to a particular feature would to be conduct a regression analysis using data from many sales.
Residential Appraisers need to up their game or they do face the possibility of losing a business in the future as AVM models improve. From an investor's perspective, there would be absolutely no reason to utilize appraisers if they concluded that collateral risk can be better managed using AVM's. That is not the case today, but it could be the case at some point in the future.
