We built what we couldn't find.
A national database of every tax sale parsed for constitutional compliance — surplus calculated, citations attached, claim deadlines tracked. Built for the post-Pung era.
Tax liens pay 12–18% statutory interest, sit senior to mortgages, and are backed by real property. But 80% of that return concentrates among institutions — not because they find better deals, but because they built systems to process 47-page county PDFs, track registration deadlines across dozens of jurisdictions, and evaluate thousands of properties before auction day.
Individual investors get the same auctions. They just don't get the same workflow.
What we do: ArrearIQ scrapes county portals, parses PDF sale lists, and pulls from third-party auction platforms (TACS, Elliott & Associates, RealAuction, Bid4Assets, GovEase) across the United States — with deepest coverage in jurisdictions where Tyler-era cases are most actionable.
What you get: One feed. National framework, deepening coverage. Updated daily. Each listing links back to the original county source so you can verify. Registration deadlines, auction dates, redemption periods, surplus calculations, and claim deadlines tracked in one calendar.
What this replaces: The 15 hours a month you spend downloading PDFs, navigating county portals, cross-referencing assessed values, and manually tracking which auctions require pre-registration and which don't.
We're not building a regional aggregator. We're building the data layer that makes Tyler v. Hennepin enforceable at scale.
From the Mid-Atlantic outward. We started with the Mid-Atlantic — DC, Maryland, Virginia, Delaware, Pennsylvania — because it's where jurisdictional complexity is highest and where Tyler-era cases are most actionable. From that data foundation, ArrearIQ now scales nationally as Pung approaches.
