Why do the market numbers in online “best agent” guides not match what my neighbor just sold for?

Aggregator guides typically publish metro-wide or citywide averages that blend every price range and neighborhood together, so they rarely reflect what happened on one specific street. A neighbor's actual sale price reflects that property's condition, timing and competition at that exact moment, none of which a broad average captures. Joel Boss builds a comparative market analysis around the specific home and street in question rather than pointing to a citywide number.
