    Quick answer: Tax delinquent properties are homes whose owners are behind on property taxes. Counties publish delinquency and tax sale lists, and owners often want to sell before a lien or deed sale. Pull the list from the county treasurer or tax collector, match owners, reach out respectfully and contract off-market. DispoKey matches those contracts with buyers within 72 hours, 60/40 in your favor, $0 upfront.

    • Get the list from the county treasurer or tax collector.
    • Learn your county's sale and redemption timeline.
    • Contact owners early and with care.

    Why tax delinquent properties make good leads

    Unpaid property taxes signal pressure. The owner may have inherited the home, moved away, run into money trouble or simply lost track of a vacant property. Many would rather sell than lose the property at a tax sale.

    These leads also come with a deadline the owner can verify, which makes your outreach concrete. Pair them with other signals such as vacancy or code issues; our guide to absentee owner lists shows how to stack data.

    Where to find tax delinquent property lists

    Start with the county office that collects property taxes, usually the treasurer or tax collector.

    • Published delinquency lists before a tax sale, often in a local newspaper or online.
    • Online tax search by parcel showing unpaid years.
    • Public records requests for a full delinquency file, where allowed.
    • Tax sale calendars listing dates and parcels.

    Cook County, Harris County and Maricopa County, for example, each run online tax payment and sale information through their treasurer or tax office websites.

    How tax sales and redemption periods work

    States handle delinquent taxes in two main ways. In tax lien states, the county sells a lien and the owner can redeem by paying the taxes, interest and costs within a set period. In tax deed states, the county sells the property itself after the delinquency process ends, sometimes with a redemption period afterward.

    Timelines, interest and notice rules differ by state, so read your state statute and your county's sale rules. Our buyer-side guide on tax lien properties explains liens in more detail.

    How to build a workable lead list

    1. Download or request the delinquency list.
    2. Filter for residential parcels and multiple delinquent years.
    3. Remove properties already in bankruptcy or with active listings.
    4. Match owners and mailing addresses from assessor records.
    5. Skip trace owners without good contact data.
    6. Tag each lead with the next sale date.

    Outreach that respects owners

    Owners behind on taxes may be embarrassed or under strain. Mail first with a short, plain letter that explains options without pressure, and tell them the county can confirm their balance.

    Follow Do Not Call and texting consent rules for any calls or texts; see our TCPA guide. Never claim to be from the county or imply a government notice.

    Underwrite with the tax debt included

    Get the exact payoff from the county, including penalties and interest, and confirm other liens through title. Taxes are paid at closing from the sale proceeds. The illustrative funnel in this guide shows how a large list narrows to a few signed contracts.

    What to say in a first letter

    Keep it short and human. Say who you are, that you noticed the property may have a tax balance, that the county can confirm the amount, and that you buy homes as-is if they want to sell. Offer a simple way to reply and a way to ask not to be contacted again. Avoid red envelopes, fake checks or anything that looks like a government or legal notice; these erode trust and can break laws.

    Follow-up cadence

    Mail again before key dates on the county calendar, such as the published sale list. Track each touch in your CRM so you never contact someone who asked to stop.

    State rules to check

    Some states regulate wholesaling or require disclosures when you market a contract. Read your state's rules and disclose your role in writing. Our guide is wholesale real estate legit covers the basics.

    How tax lists compare with other lead lists

    Tax delinquency is a strong motivation signal, but it is public and widely mailed. Stacking it with other signals helps you reach owners others miss: vacancy from mail returns, code violations, absentee ownership and probate filings. Owners who appear on two or three lists often have the most urgent need. Test each combination for a few months and compare cost per signed contract rather than response rate.

    County examples

    Cook County's Treasurer posts tax bills and payment status by property index number. Harris County's Tax Office offers property tax searches by account. Maricopa County's Treasurer publishes tax lien sale information and parcel balances. Each works differently, so spend an hour learning the search filters, the sale calendar and how often lists update before you build a campaign.
