FeaturedWhitepapersStudy: AVMetrics' Predictive Testing MethodologyIn this study, we have performed a comparative side-by-side analysis of both our Legacy and our new PTM™ testing systems. We used an outcomes analysis to see how the models were anchoring their valuation estimates after a listing price was published. We obtained value estimates for the same properties for use in both testing methodologies to ensure that the sampled properties were identical. This gave us a measure of the difference in the model(s) testing outcomes between the two methodologies. We believe that this new testing method establishes a new “normal” for the prediction accuracy of models uninfluenced by listing price testing outcomes.Read the article →FeaturedWhitepapersAVM Testing and Evaluation using AVM Performance MetricsKennedy, Ecker and Isakson measure the accuracy of AVMs and their FSDs, demonstrating that most of the time FSDs underreport forecast error.

Isakson and Lee Kennedy delivered the attached whitepaper at the 2019 4th quarter CRN meeting in Las Vegas, NV on September 30, 2019. Abstract This case presents a thorough exposition of the state-of-the-art in the calculation and interpretation of Automated Valuation Model (“AVM”) Performance Metrics, including the…Read the article →FeaturedWhitepapersThe Many Uses of Automated Valuation Models (AVMs)By Lee Kennedy, Founder, AVMetrics LLC Introduction In this paper we will focus on some of the many ways AVMs are being leveraged in mortgage banking. First, a quick refresher. An AVM is a predictive model designed to estimate a property’s value. The usefulness of an AVM can generally be determined by the extent to…Read the article →
