Abstract

An automated valuation model that uses condition and quality variables. In response to user queries, the model ranks and displays comparables for a subject property. The comparables are selected based on their similarity to the subject. Data on quality and condition of properties is incorporated into the model and corresponding comparable assessments. For example, the quality and condition inputs may be used in a hedonic adjustment factor model, comparable selection exclusion rules, economic distance calculations, and adjustments for differences between the subject and comparables at comparable selection stage. The comparables may be displayed in ranked order based on the calculated similarities between the properties, with indications of the quality and condition categories, to provide an overall assessment of the comparables as well as displayable indications of the underlying quality and condition categories and related information. The model may also use other ordinal variables and may perform any type of valuation.
