Sale Type Definitions

Tax Lien, Tax Deed, Redeemable Deed — each works differently. Lientac explains each type in plain English and surfaces relevant rules per county, so you always know what you're bidding on and what rights you acquire.

County Auction Links

Direct links to the official county auction registration pages for every jurisdiction we cover. One click to register, bid, or verify official listing data — no more hunting government websites for the right page.

"Finally a way to scope out a whole county auction in 20 minutes. I can see which neighborhoods are clustered with liens and avoid the ones near industrial zones — that context just wasn't possible before."

"The county auction links alone save me an hour per auction. I used to bookmark 12 different county portals. Now it's all one place with direct links to register. Should've existed 10 years ago."

"The sale type definitions are genuinely useful. I kept confusing redeemable deeds with regular tax deeds — Lientac explains each one with the actual redemption periods for the state. No more Wikipedia rabbit holes."
