Lake County anchors NW Indiana — Gary, Hammond, East Chicago, Merrillville — within the Chicago metropolitan area. Heavy IL-mailing investor pattern surfaces Chicago-based operators with NW Indiana property holdings. This report maps 242,723 parcels into 3,184 ownership concentration clusters using publicly available county assessor records, including Gary, Hammond, East Chicago, Merrillville, Crown Point, Schererville, and Munster. Indiana assesses every parcel at 100% of true tax value (= market-value-in-use) per IC 6-1.1-31 — no assessment-to-market multiplier. Circuit breaker caps (1% homestead / 2% other-residential / 3% non-residential) apply to the tax bill, not the assessed value.
NW Indiana / Chicago commuter market. Lake anchors Gary, Hammond, East Chicago, and Merrillville — firmly inside the Chicago metropolitan area. 242,723 parcels, 3,184 ownership concentration clusters.
Cross-state Chicago investor pattern. Lake County's mailing-address data captures the Cook-County-based investor footprint that defines NW Indiana's rental market. Chicago Loop registered-agent towers (208/120/221 N LaSalle, 233 S Wacker, 555 W Madison) are pre-loaded as virtual offices to suppress false-positive clusters at those addresses.
Standard tier — values pending IGIO enrichment. Lake's primary feed is geometry + ownership only; assessed values, year built, and living area come from the Indiana statewide GDB and will be added in a future update. Cluster identification, mailing-address co-location detection, and DLGF property class data are unaffected and complete.
Pairs with Illinois Metro East counties. Lake operators frequently appear in St. Clair County, IL and Madison County, IL clusters — the bi-state pattern is visible only when both sides of the border are mapped together.
