ERES from European Real Estate Society (ERES)

Abstract: The US housing sector is the largest market for real estate valuation models, generically known as Automated Valuation Models (AVMs). The mortgage industryís increasing rate of adoption of these models, however, has not been matched by a disciplined approach to model validation. A three-stage AVM testing and validation approach is recommended. Emphasis should be placed on evaluating data sources, modeling techniques and analysis of the test results in a proper statistical context.
