Where Our Tax-Delinquent Property Data Comes From
LienSuite builds its tax-delinquency data from county records, not from a third-party data broker. Three routes bring records in: files a county tax office publishes itself, county web systems read on a schedule, and formal public-records requests when a county publishes no list. Every record is normalized to one schema, matched to the county's own parcel identifier, and stored with the county and state it came from. A property is counted as tax-delinquent only when it owes back taxes or is multiple years behind - the rest of a county's parcel roll is tracked separately and never counted as delinquent. As of 2026-09-09, that produces 1,946,877 delinquent records across 508 counties in 39 states. Of those 508 counties, 321 were re-collected from their county source in the last 30 days and 351 in the last 90, covering 88% and 91% of published records. Each county runs on its own release cycle, so freshness is a distribution, not a single date.

Where the records come from
Counties do not publish delinquency data the same way, so there are three intake routes. Every record keeps the county and state it came from, plus the county's own parcel identifier, so any row can be traced back to its source.
Files the county publishes
Most counties post a delinquent tax roll, a tax-sale or struck-off list, or a certified delinquency file on the tax collector's or appraisal district's website. Those files are downloaded and parsed on a schedule.
County web systems
Where there is no downloadable file, the county's own property search, tax-roll system, or public parcel layer is read on a schedule for the same fields the file would have contained.
Public-records requests
When a county publishes nothing, the list is requested under that state's public-records law (open records / FOIA / PIA). Those responses arrive as files and are parsed like any other county file.
What LienSuite does not do: buy a data broker's national file and resell it, infer a delinquency a county did not report, or fill in a missing amount owed with a model.
How a record becomes “tax-delinquent”
A property counts as tax-delinquent when it owes back property taxes or is two or more years behind. Nothing else qualifies.
This matters because many counties publish delinquency data inside a full appraisal or parcel roll - every property in the county, delinquent or not. Publishing that roll as a delinquent count would inflate a county's number many times over. LienSuite keeps the full roll for parcel coverage, but the delinquent figure on any public page counts only records that meet the definition above.
How current the data is
Three different dates get called “last updated” in this business, and they do not mean the same thing. Measured live across the 508 counties holding delinquent inventory today:
- 1.The date the county published. The vintage printed on the county's own file. It is recorded where a county states one and shown on that county's page. It is not averaged into a national figure, because most counties do not state one.
- 2.The date we collected it. When that county's file was last pulled or its system last read. That is what the figures above count, and it is our clock, not the county's.
- 3.The date counts were recalculated. 2026-09-09. That is arithmetic over records already held. A recalculation does not mean a county published anything that day, and it is never shown as if it did.
145 of these counties have no collection run on record, so no re-collection date is claimed for them anywhere on the site. Every figure here is scoped by county and state, never by county name alone, so one state's collection can never be credited to another state's inventory.
What is checked before a number is published
- 1.Parse accuracy. Parsed rows are compared against the county's own file. An import that does not match its source is rejected instead of published.
- 2.Roll-padding guard. If a county's delinquent count comes back larger than its total record count, that county is treated as corrupt and excluded from every published aggregate until it is re-imported.
- 3.County and state scoping. Records are keyed by county and state. Dozens of county names exist in more than one state, so a name-only match would blend two counties' data together.
- 4.Corrections are retroactive. When a bad import is found, the affected values are cleared and the county is re-imported. Public counts move down when that happens, and that is the intended behavior.
What this data is not
- Not a payoff quote. Balances change daily as owners pay. Figures are accurate as of the refresh date shown, and the county tax office is the final authority.
- Not a title search. Delinquency records show the tax position, not every recorded lien, judgment, or encumbrance against a property.
- Not legal advice. Redemption periods, bidding rules, and surplus-claim procedures are set by state statute and county practice.
- Property values are estimates, and partial. A known valuation exists for about 73% of delinquent records; the rest are shown without a value rather than with a guessed one.

Common questions
Where does LienSuite get its tax-delinquent property data?
Directly from county sources: delinquent tax rolls and tax-sale lists published by county tax offices, county appraisal and assessor systems, and public-records requests filed with the county when no list is published. LienSuite does not buy or resell a third-party data broker's file. As of 2026-09-09 the dataset holds 1,946,877 delinquent records across 508 counties in 39 states.
What counts as a tax-delinquent property?
A property is counted as tax-delinquent when it owes back property taxes or is two or more years behind. That is the same definition used everywhere in the product. Properties on a county appraisal roll with no unpaid taxes are tracked as parcel coverage and are never included in a delinquent count.
How often is the data updated?
Every county publishes on its own cycle, so the honest answer is a distribution rather than one date. Of the 508 counties holding delinquent inventory, 321 were re-collected from their county source within the last 30 days (88% of published records) and 351 within 90 days (91%). The counts on this page were last recalculated 2026-09-09 - that is our cache doing arithmetic on records already held, not a county publishing that day. A county's own tax office is always the final authority on a current balance.
How accurate is the data?
Each import is parsed from the county's own file and checked before it is published: rows where a county's delinquent count exceeds its total record count are treated as corrupt and excluded from every published figure, and an import that does not match its source file is rejected rather than published. Amounts owed change daily as owners pay, so treat any figure here as of the refresh date, not as a payoff quote.

Yes. The statistics on LienSuite's public data pages are free to cite with attribution under CC BY 4.0. If you find a number that looks wrong, email [email protected] with the county and the figure and it will be checked against the county source.
