A narrated walkthrough: find tax liens by county, read the Research Score, risk flags and sources, set your maximum bid and save a Deal Radar.
Read the transcript
If you came here for tax liens, start in Property Research and choose Tax Lien.
Liens without a set sale date sit under Timing not assigned yet. That includes over the counter liens you can buy now, with no auction.
Pick a state and a county. I'll use Maricopa County, Arizona.
Tick Mapped only to see each lien on the map, and switch to aerial imagery to look at the property from above.
Open a lien to see the full research.
The Research Score grades it from A to D, out of one hundred, and shows where the points come from.
Estimated value and confidence gives you a value range, and tells you how far to trust it. It's a starting point, not an appraisal.
Risk flags come up before you buy: whether it's still available, liens that may survive, and a source that may be out of date. Open one to see what to check.
The due diligence checklist shows the lien to value ratio and the back taxes, and what you still need to verify yourself.
Sources and freshness links every fact back to the county's own record.
Then calculate your maximum bid. You get a comfortable range, a caution range, and the price where you should stop.
Back in Research, mark it as a bid candidate, and add private notes that only you can see.
Save your search as a Deal Radar, and new matches come to you by email.
That's tax liens: from a county to a lien worth buying, with every fact sourced to the county.
Before the Auction
Find your county auction date. Most counties hold tax sales on the first Tuesday of the month. Download the auction list three weeks beforehand. Study the properties. Set your maximum bids. Prepare a cashier check for the amount you plan to spend.
Auction Day Registration
Arrive at 8:30 AM for a 10 AM auction. Bring your ID and proof you do not owe delinquent taxes in that county. Registration takes 15 minutes. You receive a bidder card. No background check, no license, no course required.
The Auction Itself
The constable reads each property, announces the minimum bid, and waits for hands. Most properties get no bids. When you raise your card, the constable asks for other bidders. If none, you win at the minimum. Pay immediately with your cashier check.

The auction: bid-down vs. premium, and setting your max
Bid-down lowers your interest rate and premium bidding raises your price, either way, decide your maximum before the auction starts.
Marcus Field: Go Watch Before You Bid
My best advice is to attend an auction as an observer before your first purchase. Watch the rhythm. See how bidding works. Notice which properties attract competition. I did this for two months before my first bid and it saved me from costly rookie mistakes.
Walking into your first county tax auction can be intimidating. I remember sitting in the Cameron County courthouse, watching experienced bidders flip through thick binders of properties while I nervously clutched my single printed list. Here is exactly what to expect so you can walk in with confidence.
County tax auctions are usually held monthly on the first Tuesday. Some larger counties hold weekly auctions. The auction is typically held at the county courthouse in the commissioners courtroom or a similar public space. Registration begins 30 to 60 minutes before the auction. You will need a government-issued ID and proof that you do not owe delinquent taxes in that county.
Once registered, you receive a bidder number. Some counties require a deposit in the form of a cashier check or cash. Others let you bid first and pay after you win. Know the payment rules before you attend. I bring multiple cashier checks in different amounts so I can pay immediately if I win.
The auction itself moves quickly. The constable or auctioneer reads each property address or parcel number, announces the minimum bid, and scans the room for bidders. If no one bids, the property is struck off to the county. If someone bids, the auctioneer opens the floor for competing bids. Most properties sell at the minimum bid because there are fewer bidders than you expect.
When you win, you pay immediately or within a specified window. You receive a receipt and, in some counties, a temporary certificate. The official certificate arrives by mail weeks or months later.
The most important thing I can tell you is to attend at least one auction as an observer before you bid. Watch the process. Note which properties get multiple bids. See how the auctioneer handles tie bids. Learn the rhythm. I watched two auctions before my first bid, and that preparation saved me from expensive rookie mistakes.
