A method and computer program product are disclosed to provide a single, reliable reconciled property valuation for a subject property when presented with multiple property valuation estimates from vendors, brokers, and/or agents. The method includes steps to store a plurality of independent property valuation estimates, identify a plurality of property characteristics that are common between the property valuation estimates, compute a property characteristic variance between the supporting sales comparables and/or competing listings and the subject property for each property valuation estimate, weight the property characteristic variances among the property valuation estimates for each property characteristic, and determine a most probable reconciled value by applying an algorithm to the weighted property characteristic variances.
