Limitations (read this before trusting anything)

Not an appraisal. Every value is an automated model with published error (see /methodology/accuracy). Condition-blind (today): comps aren’t yet stratified renovated/dated/distressed; a gut rehab and a shell can sit in one comp set. Guards refuse the worst sets; P1 fixes the method. 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 muni-level only; several signals (311, permits, ridership, crime) 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), and crime-family signals are excluded from any steering-adjacent public display.
