Hamilton County shares its parcel and code data through CAGIS, the GIS consortium of the county and the City of Cincinnati, and that makes it one of the most open counties in the region. Propertiz loads every parcel and owner from the Hamilton County Auditor's roll, about 420,000 parcels, adds the unpaid taxes on that roll and the code-enforcement cases from Cincinnati and its neighbors, and ranks the owners who may have a reason to sell. Here is what's on the Hamilton County page today and what isn't yet.
Unpaid property taxes on the Auditor's roll
The Auditor's roll carries each parcel's unpaid taxes next to its yearly tax bill, and the county refreshes it every month. It covers the whole county, Cincinnati and the rest of Hamilton County alike.
In Ohio a delinquency counts only when the parcel is certified delinquent or owes at least one full year's tax, because a balance on an Ohio roll is often a single missed half-year payment. Hamilton's roll doesn't mark which parcels are certified delinquent, so Propertiz uses the second test: the unpaid amount must be at least the parcel's yearly tax. The number of years owed is the balance divided by that yearly tax, and two or more years weighs more than one. Only the newest snapshot counts, so a parcel that pays off drops out.
The Hamilton County Treasurer sells tax lien certificates each October. A certificate holder can foreclose after a one-year wait, and tax foreclosures end in a sheriff sale. Our guide to Ohio foreclosure and tax delinquency explains each route.
Code enforcement in Cincinnati and its neighbors
Cincinnati publishes the county's shared code-enforcement dataset, updated daily. It covers Cincinnati and the communities on the same system, including Blue Ash, Norwood, Forest Park and Sycamore. Propertiz keeps the case types about the condition of a property:
- residential building code cases and the city's neighborhood code-enforcement program,
- barricaded buildings and demolitions, which usually mean a vacant structure,
- residential zoning and lead-paint cases, and
- the suburbs' property-maintenance codes.
Litter, tall grass, abandoned vehicles, graffiti and commercial-building cases are left out. The dataset has no parcel number, so each case is matched to a parcel by its address, inside Hamilton County only. Open cases count as distress and fade as they age, and a case stops counting when it closes.
Owners and the homestead flag
The roll gives the owner, the owner's own address (the tax-bill address only as a fallback, never a lender's tax service), the site address, land use, market value, last sale and unit count. Square footage comes from the county's building footprints, so square footage and bedrooms are estimates.
Ohio's homestead exemption is for seniors and disabled owners. When Hamilton's roll shows the exemption, Propertiz treats the owner as living in the house. When it doesn't, owner-occupancy is left unknown, so a missing exemption doesn't count against the owner.
What isn't in Hamilton County yet
- Foreclosure filings. Ohio forecloses through the courts, and Hamilton's filings aren't included yet. The Auditor's roll has a foreclosure flag, but it is never set, so Propertiz doesn't use it.
- Sheriff sale dates.
- Probate filings.
- Evictions.
How Cincinnati leads are ranked
The rules are the same in every Propertiz county. A lead needs at least one active distress signal: unpaid taxes that pass the Ohio test, or an open code case. Owner traits then add points, such as an absentee or out-of-state owner, long ownership and high estimated equity. Points from different signals add up, so a barricaded house with a year of unpaid taxes scores higher than either signal alone.
Every lead is underwritten as a long-term rental with an equity estimate, a HUD market rent and a DSCR at your purchase price. Ohio taxes the county auditor's value, and a sale can trigger a new appraisal, so today's bill can understate a new owner's. Run your own terms through the DSCR calculator.
Working Hamilton County leads
All data is public under Ohio's Public Records Act (R.C. 149.43). Contact owners respectfully. Mail first; follow federal rules (TCPA, Do Not Call) and Ohio's telephone-solicitation law (R.C. Chapter 4719) for calls and texts. No leaseback or "save your home" offers to owners in foreclosure. If you assign contracts, Ohio requires a written wholesaler disclosure to the seller.
