Hamilton County anchors the Cincinnati metro and produces the highest cluster count of any Ohio county in the catalog. This report maps 356,045 parcels into 2,964 ownership concentration clusters using publicly available county auditor records, including Cincinnati, Norwood, Blue Ash, Montgomery, Madeira, and Forest Park. Ohio market value is used directly, and both the narrow homestead exemption and the 2.5% owner-occupancy reduction feed owner-occupied detection.
Highest Ohio cluster count — 2,964 clusters. Hamilton produces more ownership concentration clusters than any other Ohio county in the catalog. National escrow operators (Cotality/Lereta-style address servicers) show up as very large co-location clusters unique to Cincinnati.
$21.97 billion clustered value. Second-highest total clustered value of any Ohio county after Columbus. Cincinnati's mix of urban-core institutional real-estate and suburban investor portfolios drives cluster depth across multiple municipalities.
Dual owner-occupancy flags. Hamilton's Auditor data carries both the senior/disabled homestead flag and the 2.5% owner-occupancy reduction. When either is present the parcel is flagged owner-occupied, giving a more complete absentee denominator than single-flag counties.
Cincinnati-Canton corridor. Pair with Stark County (Canton) to see I-77 corridor investor overlap — Cincinnati-based operators frequently hold Canton rental portfolios, and the paired analysis surfaces cross-metro concentration.
Pairs with the Ohio Statewide bundle. Cincinnati operators extend into other Ohio metros. The Ohio Statewide 5-County Bundle covers 1.57M parcels across Columbus, Cincinnati, Dayton, Canton, and Akron.
