The Problem

A $5 billion market still running on paper

When homeowners don't pay property taxes, counties sell the debt as tax lien certificates. Investors buy them and earn 8–36% interest, backed by real estate. It's one of the most consistent asset classes in the US. But the tools? County websites from 2003, downloadable CSVs with no context, and manual due diligence that takes hours per property. The information asymmetry is enormous. The investors who win are the ones who can process data fastest.

02

AI Property Valuation

Every property gets an instant AI valuation using comparable sales, assessor data, satellite imagery, and neighborhood trends. Know what it's worth before you bid.

ROI Prediction Engine

Our model predicts redemption probability, expected interest, and downside risk for each lien. No more guessing. Every bid backed by data.

04

Each state has different auction rules: bid-down interest, premium bidding, rotation. ParcelAlpha optimizes your strategy for each county's specific mechanics.
