Use cases

• Rank Cincinnati-area delinquent parcels by balance and contact owners at their separate mailing addresses.
• Tax-lien and tax-sale researchers building a Hamilton County working list by amount owed.
• Property-tax lenders and servicers monitoring delinquency on a known parcel.
• Real-estate attorneys and title researchers checking unpaid taxes before a transaction.
• Investors and developers screening by market value and delinquent balance.

Coverage and freshness

• 126,000 parcels in the current CAGIS Hamilton County parcel service.
• 8,287 parcels carry a positive delinquent-tax balance; 8,281 distinct parcel IDs because a few condominium parcels have more than one unit row.
• Total published delinquency is about $28.7 million, with an average balance of about $3,463 and a range from $0.01 to $363,292.73.
• 5,199 parcels owe at least $1,000.

It publishes a delinquent-tax balance, not a recorded lien instrument. There is no lien instrument number, recording date or filing book/page in this dataset, and the actor does not invent one. The lien holder is recorded as Hamilton County, Ohio because the unpaid charge is owed to the county.

FAQ

Is this a credit report?

No. This is public-record research from a county parcel and tax dataset.

Is the amount a filed lien amount?

No. It is the county's published delinquent property-tax balance for the parcel. Hamilton County records actual lien instruments in a separate office, and this dataset does not publish an instrument number or recording date. Use this actor for delinquency screening and parcel-level research, not as a title examination.

Can I search by owner?

Yes. Add one or more names to ownerNames. Partial names work, so SMITH returns every matching owner line and PROPERTIES returns business owners with that word in the name.

Can I look up one parcel?

Yes. Put the 12-digit parcel ID, 11-digit auditor parcel ID, 14-digit property ID or group parcel ID in parcelNumbers.

Are the amounts final payoff figures?

No. Treat them as published at the time of the run. Confirm a payoff with the tax office before relying on it.
