Comparable sales (comps) and a lightweight automated valuation for a Cook County / Chicago property: recent arm's-length sales in the same assessor neighborhood and property class over the last 18 months, with an implied low/median/high price range, each comp carrying its distance in metres from the subject. Thin markets widen automatically (36 months, then the property-class group) and the response reports which rung was used. Non-arm's-length and multi-parcel deeds are filtered out — a derived valuation you won't get from a raw open-data query. For valuation, underwriting, investment screening, and due diligence.
