About Keystone Court Data the organization
Keystone Court Data LLC was founded in 2024 to fill a specific gap in real estate market intelligence: court-record-stage foreclosure data, delivered the same day they're filed.
National foreclosure-data aggregators combine every stage of the foreclosure process (default notices, scheduled auctions, REO transfers) into broad market totals, which suits total-market-size questions. Keystone Court Data covers one specific stage: the foreclosure complaint (lis pendens), the same day it's filed.
The same approach extends across other case types where the court filing is the earliest-detectable signal: probate openings, divorce filings with joint property ownership, partition actions, tax-sale notices, and guardianship filings with real-property implications.
States served
Coverage grows county by county. The full directory lists every state and county we cover today, and each county page shows exactly which lead types it carries.
Editorial standards
Every statistic on this site is computed against the court-records dataset described in our methodology page. We apply the following standards across all research notes, county intelligence reports, and investor guides:
- Aggregate publication only. No individual case data, no defendant names, no exact property addresses. Reports show percentages and distributions.
- Entity filings excluded. Filings where the party is an LLC, trust, or bank rather than a person are excluded from the dataset that powers reports.
- Sample-size thresholds. A county or state report is published only when there is enough verified data behind it, and small breakouts are never the basis for a headline claim.
- Source attribution. Every external statistic cites its source (e.g. "per US Census ACS 2023 5-year"). We do not present unsourced numbers.
- Sanity clamps + accuracy gates. Computed values are sanity-clamped to realistic ranges (vacancy rate 0-50%, percentages 0-100, etc.). Outliers from data-feed glitches are excluded rather than published.
- Methodology divergence disclosed. When our counts differ from those published by national industry aggregators, the methodology difference is explained on the report. See the how-we-compare-to-aggregators section for details.
- Generated dates inline. Every report shows its generation date so readers can judge how recent the underlying data is.
- Partial-data signaling. When the current calendar month is in progress, trend math excludes the partial month and the table labels it as such.
Data sources
Reports are built on a combination of:
- Primary: public court filings in the counties we cover, matched to the owner and property.
- Free government data layer: US Census American Community Survey 5-year (housing stock, demographics, vacancy); US Census Building Permits Survey (annual permits); FRED Federal Reserve Economic Data (state home price indices, national mortgage delinquency rate); HUD User API (Fair Market Rent); Wikipedia REST API (county summaries); BLS (state unemployment).
- National benchmark citation: A national foreclosure-data provider's Q1 2026 market report, for national context (cited but not relicensed; our reports use our own court-record counts).
Corrections policy
We correct errors quickly and visibly. If you find an error in any published report:
- Email carson@keystonecourtdata.com with the report URL, the specific statistic in question, and the corrected value with source.
- We respond within 48 hours for editorial corrections (faster for material accuracy issues).
- Substantive corrections are noted on the report itself with an "Updated [date]: [what changed]" footnote. We don't silently overwrite previously-published numbers.
