The Problem

Three Ways Investors Lose Money

01

Missed Redemption Deadlines

Redemption periods vary wildly by state — Florida is 2 years, Georgia is 0. Without precise tracking, you miss your window and lose accrued interest or the property entirely.

02

Auction Discovery is a Full-Time Job

3,000+ counties hold tax sales. Schedules live on obscure government sites. You're missing auctions you didn't even know existed.

03

Unstructured Due Diligence

IRS federal liens survive tax foreclosure. HOA liens may too. Without a checklist tied to your state's rules, you skip steps and buy expensive mistakes.

Features

Everything You Need to Invest With Confidence

Auction Discovery

Browse upcoming tax lien and deed auctions across 10 priority states. Filter by state, sale type, and date.

Deadline Alerts

State-aware deadline calculations with 90/60/30/14/7/3/1-day alerts before critical windows expire.

Due Diligence Checklists

State-specific checklists auto-populate on every asset. IRS lien searches, title checks, HOA verification — built in.

Portfolio ROI Tracker

Track acquisition cost, expenses, redemption amounts, and sale prices. See your real return on every deal.

State Law Reference
