16 Best Counties for Tax Lien Investing in 2026
TL;DR
The best counties for tax lien and tax deed investing balance low bidder competition with real, sellable inventory and a clear redemption/foreclosure path. Cameron County TX, Duval County FL, and Pima County AZ remain top beginner picks for 2026 -- this expanded ranking adds the higher-volume metro counties (Maricopa, Cook, Baltimore City) worth knowing even though they run more competitive.
1. Cameron County, Texas
Cameron County is the best county in the country for beginning tax lien investors. It runs monthly online auctions through RealAuction, has consistently low bidder turnout relative to its inventory, and lists many properties where the delinquent taxes are small relative to assessed value. As a Texas redeemable-deed county, you buy the property outright and collect a flat 25% premium (not accruing interest) if the former owner redeems within 180 days for most property, or up to 50% across a 2-year window for homestead, agricultural, or mineral property -- so the opening bid frequently clears at or near the total back-tax amount since so few investors compete for it.
2. El Paso County, Texas
El Paso County offers the same Texas redeemable-deed mechanics as Cameron -- 25% flat premium in year one, up to 50% across two years for protected property classes -- with even thinner bidder turnout. The county's population is growing, which supports underlying property values even as competition stays low. Auctions run monthly, online through the county's designated platform, and opening bids are typically set at the judgment amount (back taxes, penalties and court costs), not the property's market value.
3. Duval County, Florida
Jacksonville's Duval County runs Florida's dual system: tax lien certificates (statutory cap 18%/yr, 5% mandatory minimum penalty, bid down by rate in open auction) that convert to a tax deed application if unredeemed after two years. Competition on certificates is real but noticeably lighter than Miami-Dade or Broward, where institutional funds routinely bid rates down toward the 5% floor. Duval's deed auctions -- for certificates that go unredeemed -- draw a smaller, more local bidder pool than South Florida's metro counties.
4. Pima County, Arizona
Tucson's Pima County runs Arizona's online lien-certificate auction with meaningfully less institutional competition than Maricopa County (Phoenix). Arizona's 16%/yr statutory ceiling is bid down in open auction, but Pima's rates have historically held up better than Maricopa's core because fewer large funds bother competing in a secondary market. The state's 3-year redemption period -- the longest of any major lien state -- gives certificates more time to either redeem (paying you the accrued rate) or become eligible for judicial foreclosure into a deed.
5. El Paso County, Colorado
Colorado Springs' El Paso County (not to be confused with El Paso, Texas) offers Colorado's lien-certificate system -- rate set annually at nine points over the Federal discount rate (roughly the mid-teens in recent cycles), premium bid, non-refundable -- with lower competition and a smaller institutional presence than Denver County. The 3-year redemption period and the growing population along Colorado's Front Range support both redemption likelihood and, if it comes to that, the value of any property acquired via deed.
6. Tarrant County, Texas
Fort Worth's Tarrant County runs the same Texas redeemable-deed mechanics as Cameron and El Paso, but with a deeper, more competitive bidder pool -- more investors know about it than Cameron/El Paso, though still meaningfully fewer than Dallas or Harris (Houston) County. Auctions are monthly, first-Tuesday, with a mix of in-person and online sales depending on the precinct. The local economy (aerospace, logistics, and a growing DFW metro) supports redemption rates on the properties that do come back.
7. Fulton County, Georgia
Atlanta's Fulton County has the highest tax deed auction volume in Georgia, with moderate-to-heavy bidder competition reflecting the metro's size. Georgia is a redeemable-deed state like Texas but with different numbers: a flat 20% penalty in year one, plus 10% for each additional year the property goes unredeemed, on a 12-month base redemption window. Cleanup and demolition liability can attach to the property during that redemption window, which is a real cost investors in Fulton specifically should budget for given the county's older urban housing stock.
8. Lee County, Florida
Fort Myers' Lee County runs Florida's lien-then-deed system with less institutional competition than the Miami-Dade/Broward/Tampa Bay corridor. Population growth in Southwest Florida has been pushing property values higher, which improves the deed-auction economics on certificates that go unredeemed past the 2-year window. Certificate rates are still bid down from the 18% statutory cap, just not as aggressively as in the largest South Florida counties.
9. Maricopa County, Arizona
Phoenix's Maricopa County runs the largest tax lien auction in Arizona and one of the largest online lien sales in the country by parcel count. That scale cuts both ways: deep inventory, but heavy institutional-fund participation that regularly bids the statutory 16% ceiling down toward the low single digits in the most contested parcels -- documented drops from double-digit to mid-single-digit realized rates have occurred here within a single auction cycle as bank and fund capital rotated in. Arizona's 3-year redemption period still applies, so a certificate that doesn't get bid down to nothing can be a reasonable buy-and-hold; new investors are usually better served starting in a smaller Arizona county (like Pima) before competing here.
10. Cook County, Illinois
Chicago's Cook County runs the highest-volume tax lien sale in the Midwest under Illinois's penalty structure -- not an annual interest rate but a per-6-month penalty that can compound toward a ~36%/yr equivalent if held the maximum 2-2.5-year redemption period. Because bidders compete on the penalty percentage itself (a reverse-Dutch-style auction) rather than a bid-down interest rate, realized returns vary parcel by parcel; competitive bidding is real given the county's size, but the underlying mechanics differ enough from a bid-down state that it rewards investors who specifically study Illinois's penalty-bid process rather than assuming it behaves like Florida or Arizona.
11. Baltimore City, Maryland
Maryland sets lien rates and redemption periods by county, and Baltimore City runs a notably shorter 6-month redemption in most cases but a longer roughly 9-month window on owner-occupied residential property specifically -- both faster than the rest of the state. The city's large stock of vacant and tax-delinquent parcels means high volume, but that same volume draws serious investor and nonprofit competition on the more sellable properties; the county-set rate (Maryland ranges roughly 6-24%/yr depending on jurisdiction) and the fast redemption clock reward investors who can turn around research quickly rather than sit on a certificate for years.
12. Bexar County, Texas
San Antonio's Bexar County runs Texas's standard redeemable-deed structure -- 25% flat premium in year one, up to 50% across two years for homestead/ag/mineral property -- but with more bidder competition than Cameron or El Paso simply because more investors are aware of a major-metro Texas county. It's still a reasonable step up from the smaller South Texas counties for investors who've done a few Cameron/El Paso auctions and want more volume without jumping straight to Dallas or Harris.
13. Wayne County, Michigan
Detroit's Wayne County runs Michigan's tax-foreclosure deed auction -- no lien certificates, no redemption after the sale, you're buying the property outright at whatever the county's two-round auction (a minimum-bid round, then a no-minimum second round for anything unsold) sets. Michigan's foreclosure process runs on a roughly 1-year timeline from forfeiture to auction, shorter than most deed states, which means faster turnaround but also demands fast, careful title and condition due diligence -- Wayne County's low opening bids attract a large bidder pool specifically because of Detroit's well-known inventory of low-cost properties, so 'cheap' does not mean 'uncompetitive' here.
14. Jefferson County, Alabama
Birmingham's Jefferson County runs Alabama's lien-certificate system -- statutory cap 12%/yr, bid down to as low as 0% in competitive parcels, with a separate 8% cap on the overbid amount for properties that go to deed. The metro draws more bidder interest than Alabama's rural counties, so realized rates run lower than you'd see in a small-county Alabama sale, but the 3-year redemption period and Birmingham's larger economy give redemption and resale prospects a stronger floor than thinner rural markets.
15. Franklin County, Ohio
Columbus's Franklin County runs Ohio's bid-down lien system (statutory ceiling up to 18%/yr) with moderate competition -- more than a rural Ohio county, less than Cuyahoga (Cleveland) or Hamilton (Cincinnati). Ohio's 1-year redemption period is on the shorter side nationally, so certificates turn over faster than in a 2-3 year state. Minimum bids across Ohio's smaller and mid-size counties are often set low relative to other states -- frequently in the low hundreds to low thousands of dollars -- though Franklin's growing population has been pushing bidding above the bare minimum more often than it used to.
16. Hillsborough County, Florida
Tampa's Hillsborough County runs Florida's standard lien-then-deed system with meaningfully less institutional bid-down pressure than Miami-Dade or Broward, though more than a small rural Florida county. Certificates are still capped at 18%/yr with a 5% minimum-penalty floor and a 2-year window before an unredeemed certificate can go to deed application. Tampa Bay's population growth has been supporting both redemption rates and, for certificates that don't redeem, the resale value of the underlying property.
