Tax Lien Intelligence Platform
See every tax lien auction that matters, in one view
ArrearsIQ aggregates municipal tax lien and tax deed auction data into a single, map-driven workspace so funds, family offices, and advanced investors can screen, compare, and export opportunities across counties in minutes.
Built for tax lien funds, family offices, and institutional buyers.
Why ArrearsIQ exists
Today, serious tax lien investors still live in county portals, PDF lists, and siloed spreadsheets. Every jurisdiction publishes data in its own way and on its own schedule. Teams lose hours chasing updates and reformatting lists before they can even apply their process.
ArrearsIQ turns that chaos into a single chart. The platform monitors official municipal sources, ingests auction lists and parcel files, and normalizes the fields that matter. Users log in, pick geography, set filters, and work from one consistent view that stays in sync as counties change their lists.
What you get with ArrearsIQ
A unified workspace for tax lien discovery, analysis, and execution.
One map for all your auctions
ArrearsIQ presents tax lien and tax deed sales across covered counties in a unified interface. A StreetEasy-style map stays in sync with a sortable table so your team always works from the same live view.
Fields underwriters actually use
For each sale, ArrearsIQ exposes parcel identifiers, property type, delinquent balance, interest structure, redemption period, and sale mechanic. You see liens on comparable footing across jurisdictions.
Exports that fit your models
Once a screen matches your strategy, export a clean CSV or connect to your own tools. ArrearsIQ preserves your filters as reusable screens and keeps the results fresh as sources update.
How ArrearsIQ works
From county portals to your workflow in three steps.
Collect
ArrearsIQ monitors county and state tax sale portals, clerk and treasurer sites, and related public records. Each feed is tracked with its source, coverage notes, and update cadence.
Normalize
As new lists arrive, ArrearsIQ maps raw columns into a standard schema. It resolves parcel identifiers, aligns balance fields, tags sale types, and records redemption terms. Originals stay attached.
Deliver
Users choose geography, set thresholds for balance, yield, and timing, then review results in a combined map and grid. Save configurations as screens and build watchlists for specific strategies.
Data coverage
ArrearsIQ is rolling out coverage state by state, starting with high-volume tax lien and tax deed markets.
On launch, the platform focuses on selected counties in states such as Maryland, Virginia, DC, Florida, New Jersey, Arizona, and Illinois, with each county documented for sale type, cadence, and historical depth.
