Tax Lien Intelligence Platform
See every tax lien auction that matters, in one view
ArrearIQ 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 ArrearIQ 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.
ArrearIQ 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 ArrearIQ
A unified workspace for tax lien discovery, analysis, and execution.
One map for all your auctions
ArrearIQ 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.
Fields underwriters actually use
For each sale, ArrearIQ exposes parcel identifiers, property type, delinquent balance, interest structure, redemption period, and sale mechanic.
Exports that fit your models
Export a clean CSV or connect to your own tools. ArrearIQ preserves your filters as reusable screens and keeps the results fresh.
How ArrearIQ works
From county portals to your workflow in three steps.
Collect
ArrearIQ monitors county and state tax sale portals, clerk and treasurer sites, and related public records.
Normalize
ArrearIQ maps raw columns into a standard schema, resolves parcel identifiers, and aligns balance fields.
Deliver
Choose geography, set thresholds, and review results in a combined map and grid. Save as reusable screens.
Data coverage
ArrearIQ 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 Maryland, Virginia, DC, Florida, New Jersey, Arizona, and Illinois.
Tax lien and tax deed investing involves real risk, including redemption uncertainty, title and environmental issues, local policy changes, and execution risk. ArrearIQ does not provide investment recommendations or guarantees. The platform supplies data, tools, and structure so professional investors can improve discovery, comparison, and documentation of their own decisions.
