Data sources & accuracy
Last updated October 30, 2026
All listing data comes from public records published by government offices and their official sale agents. We check the sources every day, and we only show a property when its address, sale date, debt and a value are all available.

We read only public pages and public data services, at a polite rate, and we skip any site whose robots.txt asks automated tools not to visit. Each property page shows when the sheriff's list was last updated and links to the official listing (Pro).
Which listings we show
A listing appears in search, alerts and county pages only when it has a street address, a map location, a sale date, a published debt or minimum bid, and a property value. Listings that disappear from the official list are hidden after 3 days, and offices that have not updated their list for 90 days are skipped. Each property shows a data-quality score out of 10.
How values are calculated
- Nearby sales (New Jersey, Montgomery County PA): recorded sales since 2023 of similar homes nearby or in the same assessment neighbourhood, by median price per square foot or by sale-to-assessment ratio. At least 3 sales are required.
- Town ratio (New Jersey, when there are not enough sales): the tax assessment divided by the town's official assessment-to-market ratio published by the NJ Division of Taxation.
- Official values: Philadelphia OPA market value, a sheriff's appraisal, or a court-adjudged value in a Texas tax judgment, used as published.
- Equity = value − the published debt (judgment / upset price / minimum bid). It does not include other mortgages, liens, taxes, HOA dues, repairs or costs.
Known limits
- Sales are often postponed or cancelled at short notice. Always confirm with the sheriff the day before.
- Values are estimates from public data. Nobody inspects the interior; condition can change a value a lot.
- Foreclosures brought by tax-lien holders, towns or school districts are filed as tax sales because the debt shown may be only the lien, not the mortgage.
- AI summaries and reports can be wrong. Their dollar figures are calculated by our code from the numbers above, not by the AI.
