The Automated Valuation Model (AVM) utilises supervised machine learning, where a model is trained using known transaction values. Statistical techniques are used to calculate the impact of the property’s inherent characteristics and location on the value of a property. While the AVM supports the valuation process, its outputs are reviewed and refined by valuers and analysts before making a final judgement on the appropriate band a property is placed in.
