1. A computer-implemented method for evaluating a broker price opinion, comprising the steps of: extracting data from the broker price opinion; in a computer processor or microprocessor, evaluating the extracted data against a plurality of rules applicable to the type of broker price opinion, wherein each rule is assigned a particular weight; and automatically calculating in a computer processor or microprocessor a broker price opinion score based on the evaluation, wherein the broker price opinion score is calculated by summing the total of each rule that is triggered multiplied by the weight assigned to that rule, according to the following formula: Score = K 1 +  ∑ j = 1 N w jj r j / Γ where N rules are evaluated, K is a constant, F is a constant, w is the weight of a rule, and r is a variable that defaults to 0 but takes on the value 1 if the rule triggers or fires.
