Limitations (read this before trusting anything)

Not an appraisal. Every value is an automated model with published error (see /methodology/accuracy). Condition evidence is inferred: the engine separates modeled renovated/new and as-is strata, but labels are not a verified inspection of the subject or every comp. New construction/style/lot controls remain incomplete. ZIP-blended prices/rents: ZHVI/ZORI are ZIP-level — a hot block inherits its ZIP’s median (Avondale reads 60618). Coverage gaps: Lake County tax rates unavailable (portal down); suburban permits are incomplete; several signals (311, permits, ridership) are Chicago-only; ZORI covers ~288 IL ZIPs. Zoned ≠ entitled: future zoning-upside flags won’t see ARO triggers, landmarks, or aldermanic prerogative. Unscored is an answer: grey tracts/listings mean insufficient data — we don’t fill gaps with optimism. Fair housing: scores are for property/investment analysis; outputs must never be used for tenant screening or credit decisions (FCRA). Income/crime proxy fields are restricted offline diagnostics and are stripped from public payloads, scores, risk, recommendations, and lenses. Counsel review is still open.
