Methodology and sources

Method note and sources

This score uses the section evidence rubric. A number is published only when at least two criteria are sourced and one of those sources is independent of the firm. A firm with only two sourced criteria is capped at 9.0, and a 10.0 needs at least three. A criterion without a source stays blank. Zillow team figures are not a score input.
