Property value estimation employs a comparable sales technique that calculates a feature distance between a target property and corresponding comparable properties. Determining estimated values for properties includes performing a regression based upon property features for properties in a relatively large geographical area. A set of comparable properties from a section of the relatively large geographical area is identified, and a feature distance between each property from the set of comparable properties and a target property is calculated using information from the regression. The feature distance provides a quantified indication of the difference between each property from the set of comparable properties and the target property for the plurality of property features. An estimated value for the target property is then determined based upon a value of each of the comparable properties and adjustments based upon the calculated feature distances.
