Where our data comes from, and how fresh it is

Every count, date and county list on this page is read out of the table that feeds the layer at the moment you load it. A layer with nothing loaded says so. We do not estimate, interpolate or carry forward a count.

records: 236,085 · mappable records: 71,482 · code violations: 28,660 · posted tax sales: 210

Signals we do not hold

Signal	Loaded	Rows	Why not
HUD-owned (HUD Home Store)	no	—	HUD's own listing site publishes robots.txt "User-agent: * / Disallow: /" (verified 2026-10-01), so we do not crawl it and hold no HUD inventory. See /data-sources and the outlet link on a lead card.
U.S. Marshals asset-forfeiture sale	no	—	usmarshals.gov returned HTTP 403 to a plain robots.txt request (verified 2026-10-01), so its crawl rules could not be read and nothing is fetched.
Listed on an auction platform	no	—	The platforms that host these sales (bid4assets.com, realauction.com) sit behind a WAF and their terms bar automated access; the lawful substitute we DO load is the county's own statutorily-published sale list -- that is the "Posted for tax sale" layer.
Vacancy indicator	no	—	USPS vacancy data is licensed and not public; no free per-parcel vacancy source has been located. A guessed vacancy flag would be fabricated, so there is none.

States we exclude entirely

State	Restriction	Basis
WA	PROHIBITED_COMMERCIAL_LIST_USE	RCW 42.56.070(8) (verified at source 2026-09-29, app.leg.wa.gov): an agency shall not 'give, sell or provide access to lists of individuals requested for commercial purposes ... unless specifically authorized or directed by law.' King County's tax-foreclosure page requires the user to acknowledge that prohibition before opening the parcel lists. Soliciting the listed owners is a commercial use of a list of individuals, so a Washington delinquency/foreclosure list is NOT an available lead source even though WA's assignment and marketing cells are GO. F5333.	statute

Outbound outlets, and the ones we refuse

A lead card can link out to a few places. Every candidate is listed here with the evidence we collected and a verdict; only ALLOW_DEEP_LINK and ROOT_LINK_ONLY are ever rendered, and nothing is ever posted on your behalf or fetched by us.

Outlet	Host	Verdict	robots checked	robots evidence	Terms evidence
Find land buyers & investor tools on LandAtlas	www.landatlas.com	ROOT_LINK_ONLY	2026-10-01	robots.txt returns 404 -- no file at all, which is an absence of permission rather than a grant (F5456 recon, re-stated here).	Its own /terms 15.1.4 bars bots/scripts/crawlers without written authorization and 15.1.5 bars reselling, syndicating, scraping, mirroring or caching Platform data (liquidated damages $5.00/record or $25,000, 22.5). We do none of those -- and we do not construct a URL into it either: /search 307-redirects to /auth/login, so no public per-county path exists to deep-link.
Comparable public inventory: IRS seized real-property auctions	www.irsauctions.gov	ALLOW_DEEP_LINK	2026-10-01	robots.txt reads "User-agent: *" / "Allow: /" plus a Sitemap line -- the whole site is open to crawlers, so linking its own documented public index is plainly permitted.	A U.S. Treasury/IRS site. No term prohibiting hyperlinks or deep links was located on the site; federal-agency content is not copyrighted. We still only link its published listing index.
Comparable public inventory: HUD Home Store	www.hudhomestore.gov	ROOT_LINK_ONLY	2026-10-01	robots.txt reads "User-agent: *" / "Disallow: /" -- every path is closed to crawlers, so we neither fetch it nor construct a search URL into it; one plain link to the published entry point only.	HUD's own disposition site. No term prohibiting a hyperlink was located. Because robots closes every path, no per-state or per-county search URL is built.
Comparable public inventory: GSA federal real-property sales	realestatesales.gov	ROOT_LINK_ONLY	2026-10-01	robots.txt reads "User-agent: *" / "Disallow: /" -- closed to crawlers, so root link only and no constructed paths.	A U.S. General Services Administration site; no hyperlink prohibition located.
U.S. Marshals asset-forfeiture sales	www.usmarshals.gov	REFUSED	2026-10-01	robots.txt returned HTTP 403 -- we could not read the site's crawl rules at all, so we do not treat anything about it as permitted.	Not reached; the robots check already failed, and we do not go looking for a permission after being refused the file that would state it.
Lands of America / LandWatch land marketplace	www.landsofamerica.com	REFUSED	2026-10-01	robots.txt returned HTTP 403 (bot protection) -- crawl rules unreadable, so no verdict can be reached in its favour.	Not reached, same reason.

Same numbers as /api/v1/data-sources (no key needed) — the page and the API read one payload, so they cannot disagree. Per-county probe history is at /data-status.
