The first challenge most beginners face isn't evaluating properties — it's figuring out where tax auctions actually happen in their county. There's no single national tax auction database. Instead, each county publishes its own auctions through different systems, websites, and platforms. Once you know where to look, though, finding upcoming sales is straightforward.
Here's how to locate tax deed auctions in your county.
Step 1: Identify Your County's System
Different states use different terminology, and every county has its own process. Before you search, clarify what system your county uses:
- Tax Deed State? You're bidding on the property itself. Examples: Texas, Georgia, California.
- Tax Lien State? You're bidding on a lien that may later convert to a deed. Examples: Florida, Arizona, New Jersey.
- Hybrid? Some states use both systems. Check your state's real estate commission website for the official rules.
The state matters because it determines where auctions are advertised and what format they take.
Step 2: Visit Your County Assessor or Tax Collector Website
Start here. Every county maintains a website with tax sale information. Look for links labeled:
- "Tax Sales"
- "Upcoming Auctions"
- "Foreclosure Sales"
- "Delinquent Property Sales"
- "Constable Sales" (in Texas)
- "Sheriff Sales" (in many southern states)
From there, most counties link to:
- A calendar of upcoming sale dates
- A downloadable list of properties for sale
- Registration and bidding instructions
- Contact information for questions
Pro tip: Bookmark your county's tax assessor page. Check it monthly. Many counties email notifications to subscribers as well — sign up for the mailing list.
Step 3: Check for Online Bidding Platforms
Many counties now use third-party auction platforms instead of in-person-only sales. These platforms make it much easier for remote investors to participate. Look for mentions of:
- RealTDM — Used by Florida, Georgia, and other southeastern counties
- Bid4Assets — National platform covering multiple counties
- Auctions.com — Large auction aggregator
- Tax Deed Marketplace — Regional platforms in some states
If your county uses one of these platforms, you can browse available properties immediately — no registration required for viewing. Registration (which requires a deposit) opens 1–4 weeks before the sale date.
Step 4: Search State-Level Auction Aggregators
Some states maintain centralized tax sale calendars. If you're not finding your county through county-level searches, try these state resources:
- Texas: Texas A&M AgriLife Extension — maintains a statewide calendar
- Florida: FloridaAuctions.gov — aggregates all county tax auctions
- Georgia: Georgia Sheriffs' Association — lists statewide sales
- California: County auditor-controller websites (state varies by county)
Step 5: Call Your County Directly
If you're still stuck, pick up the phone. Call:
- Your County Tax Assessor or Tax Collector
- Your County Constable (Texas) or Sheriff (other states)
- Your County Clerk's office
Ask specifically: "When and where are tax deed auctions held in this county? Is there an online platform? What's the next upcoming sale date?"
County staff are used to these questions. They'll point you to the right resource in under 5 minutes.
What Information You'll Find
Once you locate your county's auction listings, expect to see:
- Property address
- Parcel number
- Opening bid amount (usually back taxes + penalties + fees)
- Property description (building type, square footage if available)
- Auction date and time
- Registration deadline (for online auctions, this is typically 2–3 days before the sale)
This is the raw data you'll use to build your pipeline of prospects to research further.
Red Flags & Next Steps
Finding auctions is just step one. After you locate your county's sales:
- Download the full property list
- Cross-reference with public records (assessor, property appraiser, county records) to understand liens, owners, and title status
- Drive by or research properties you're serious about
- Calculate your maximum bid before auction day
- Register in advance to avoid missing the deadline
A county-specific guide walks you through the entire process for your state and county, including exact registration deadlines and bidding procedures. The better prepared you are before auction day, the higher your odds of finding a profitable deal.
