Tax-Delinquent Properties

What it means

County tax collectors publish delinquency lists on a fixed schedule (usually annually or quarterly). The list includes the parcel, the owner of record on the assessor roll, and the amount owed. What it almost never includes: a phone number for that owner.

The conversion edge here comes from combining tax delinquency with other distress signals — absentee ownership, code violations, recent probate — to isolate the highest-equity, highest-motivation subset before you spend on skip tracing.

How Ava Data handles tax-delinquent properties

Ava Data appends a current phone and email to each row of your tax-delinquent list, with per-match billing so you don't pay for the share of records that won't trace cleanly. Pair with Deep Search on the highest-priority records to also pull in heirs and spouses.

In the dashboard, upload the county's CSV, get an enriched CSV back, dial from there. Through the API, the same bulk workflow can run on a schedule against the latest county pulls.

For developers: example API call

If you'd rather click than code, the Ava Data dashboard returns the same data without a single line of JSON. The snippet below is for teams wiring Ava Data into a CRM, dialer, or AI pipeline.

• Distressed Property Leads — Distressed property leads are owners of homes facing financial or physical distress — pre-foreclosure, tax-delinquent, code-violation, vacant, or inherited — and are the highest-converting segment for wholesalers and cash buyers.
• Absentee Owner — An absentee owner is the legal owner of a property whose mailing address differs from the property address — typically a landlord, an inherited-property holder, or an out-of-state investor — and a top target for off-market acquisitions.
• Pre-Foreclosure Leads — Pre-foreclosure leads are homeowners against whom a Notice of Default or Lis Pendens has been recorded but whose property has not yet been sold at auction — the window in which a cash offer can prevent foreclosure.
