The market lifecycle.
How tax lien auctions work. Where ArrearIQ fits in.
Property falls behind

Pre-public data stage. No investor action yet.
Notice & advertising
County issues notice to owner. Public advertising period begins.
ArrearIQ monitors county portals. Detects new notices.
Sale list published
County publishes official auction list (often as PDF or portal listing).
Parses PDFs. Normalizes data. Enriches with location intelligence. Scores every property.
Auction day
Competitive bidding. Liens/deeds sold to highest bidder (or lowest interest rate).
Calendar tracking. Deadline alerts. Registration reminders.
Redemption period
Owner has statutory period to pay back taxes + interest. Varies by jurisdiction.
Portfolio tracking. Redemption status monitoring.
Outcome
Either redemption (investor receives principal + interest) or foreclosure (investor may acquire property).
