Assessing the Accuracy of Individual Property Values Estimated by Automated Valuation Models

May 11, 2018

Paper by Pr. George Andrew Matysiak


Much has been written of late about how AVMs will supposedly transform the valuation profession in the future. Yet the focus has been rather on marvelling at the data mining techniques employed by AVM operators. Few have questioned the accuracy or lack of accuracy of their product.

Thus in response to demand from valuers, TEGoVA commissioned Professor Matysiak to produce this innovative work which provides simple guidelines to valuers on what they need to know in order to assess the accuracy or helpfulness of any particular AVM in valuing individual properties.
