Watch how it works
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Risk flags come up before you buy: whether it's still available, liens that may survive, and a source that may be out of date.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.
Overview of Upcoming Sales
The next three weeks bring seven verified tax sales across five states. Mark your calendar for September 9 through September 24, 2026. Each sale has a statutory date that determines bidding rules and deadlines. You should verify the specific procedures for each county before the sale date.
Early September Sales: King County and Fresno County
King County, Washington holds its tax foreclosure sale on September 9, 2026. This is a foreclosure sale, meaning you may be bidding on the property itself, not just the tax lien. Fresno County, California follows on September 10-11 with a tax-defaulted sale. California's process is different from Washington's, so review the county's terms to understand what you are purchasing.
Mid-September Sales: Bucks, Allen, and Montgomery (Tennessee)
On September 15, Bucks County, Pennsylvania conducts its upset tax sale. The next day, September 16, Allen County, Indiana holds its tax lien sale. Then on September 17, Montgomery County, Tennessee has its tax sale. These sales are spread across different states, so you can participate in multiple if you meet each county's registration requirements.

Finding tax lien sales: auctions, OTC, and calendars
Real tax-lien sales are published by the county treasurer or tax collector, not by a marketing calendar, start at the source.
Late September Pennsylvania Sales
The final week of the period features two Pennsylvania upset sales. Chester County's sale is on Monday, September 21. Montgomery County's upset sale is on September 24, but note that the sale is continued to December 10, 2026. This continuation may affect your bidding strategy, so check the county's announcements for details.
Frequently Asked Questions
Common questions about this Auction Radar edition.
Frequently Asked Questions
What is an upset tax sale?↓
An upset tax sale is a public auction where properties with delinquent taxes are sold to satisfy the debt. The minimum bid typically includes back taxes, interest, and costs. In Pennsylvania, these sales are often 'upset' because the property is sold free and clear of most liens, but the owner may have a right to redeem within a certain period.
Can I bid on multiple sales in different states?↓
Yes, you can bid in multiple counties as long as you meet each county's registration requirements. You will need to register separately for each sale and may need to provide proof of funds or a deposit. Check each county's website for specific instructions.
What does 'continued sale' mean for Montgomery County, PA?↓
A continued sale means the auction that was scheduled for September 24, 2026 will be postponed to December 10, 2026. This could happen for various reasons, such as insufficient bidders or legal issues. If you are interested in that sale, you should monitor the county's announcements for updates.
How do I find out the exact bidding rules for each sale?↓
Each county provides official sale documents and bidding instructions. You can usually find these on the county treasurer's or tax collector's website. Review the terms carefully, including registration deadlines, payment methods, and any redemption periods.
