Build a tax-delinquent property list from your AI

Build a tax delinquent list with AI in one prompt. Give Claude or ChatGPT your county and filters, and it searches tax records and saves the list.

What tax delinquency means

A property is tax delinquent when taxes go unpaid past the county's deadline. Counties publish these accounts and, if taxes stay unpaid, sell:

  • a tax lien (in tax lien states), which an investor buys and collects interest on, or
  • the property itself (in tax deed states), at a tax sale.

How fresh the data is

Many counties publish delinquency once or twice a year, sometimes only before the tax sale. A list is only as good as its date.

  • Check the record date, not only the flag. Ask your AI when each delinquency was recorded.
  • Drop resolved records. Goliath marks a delinquency resolved when the source says it's settled.

The prompt

This runs against Goliath's MCP. Check each operation in our prompt library.

Find single-family homes in Cuyahoga County, Ohio that are tax delinquent, where the owner's mailing address is out of state, with at least 40% estimated equity. Save them as a list called "Cuyahoga tax-delinquent absentee."

  1. The AI searches by county, tax delinquency, absentee owner and equity [filterProperties].
  2. It shows the count and a sample, so you can tighten filters before saving.
  3. It creates the list [createPropertyList] and adds the properties [addPropertiesToList].

Stacking with absentee, vacancy and other signals

Alone, the list mixes forgetful owners, hardship and landlords juggling cash. A second or third signal shrinks it toward real sellers.

Stack Why it helps
Tax delinquent + absentee owner The owner lives elsewhere, so the house is likely a burden. See absentee owners.
Tax delinquent + vacant No one is living there, and the bills keep coming.
Tax delinquent + code violation The city is fining them too. The house probably needs work.
Tax delinquent + probate An estate that isn't paying taxes, often with heirs out of state. See probate.
Tax delinquent + high equity There's room for a deal that still leaves the owner with money.

Ask for a stack in plain words, like tax delinquent plus vacant. The AI combines them in one search.

Reaching the owner

  • Lead with the problem, not your price. "I noticed there may be back taxes on your property on Elm St."
  • Mail works. Delinquent owners are often hard to reach by phone, and a letter naming the property gets opened.
  • Be accurate. Never imply you're from the county, and never threaten a tax sale.

General compliance (not legal advice):

  • Marketing texts and autodialed calls to cell phones generally need prior express written consent under the TCPA.
  • Check the National Do Not Call Registry before cold calls.
  • In Goliath, texting from the AI stays off until an org admin turns it on and confirms your consent practices.

Follow-up

Tax-delinquent owners often answer the third or fourth touch, especially as the tax sale nears.

  • "Create a call list from 'Cuyahoga tax-delinquent absentee'" [createCallList, addCallListContacts] puts the list in Goliath's dialer.
  • After calls, "Log these outcomes" [updateCallOutcome] and "Remind me to follow up with the not-yets in 30 days" [createTaskOnContact].
  • Re-run the search monthly.

Questions

Can ChatGPT get tax-delinquent lists from the county website? Rarely, since counties publish in different formats and schedules, often as PDFs.

How often should I rebuild my list? At least monthly, and right after your county publishes a new delinquency file or announces a tax sale.

Does Goliath sell tax-delinquent lists? No, Goliath is data and software.
