What Is Tax Liens?
Tax liens are the government's claim on a property for unpaid taxes. When an owner falls behind, the county records a lien and often sells it at auction. You're not buying the property—you're buying the right to collect the unpaid taxes plus interest. The owner has a redemption period (1–4 years depending on the state) to pay you back. If they do, you get your principal plus interest—often 8% to 18% annually, sometimes higher. About 98% of owners redeem, so most tax lien investors earn interest, not property. If they don't redeem, you may be able to foreclose and acquire the property—that's where tax deeds come in. It's a different game than buy-and-hold or BRRRR; you're betting on redemption or a distressed equity play.
A tax lien is a claim the government places on a property when the owner doesn't pay property taxes. Investors can buy the lien and earn interest when the owner pays up—or potentially acquire the property if they don't.
At a Glance
- What it is: A government claim on property for unpaid taxes. You buy the lien (certificate), not the property.
- Why it matters: Can earn 8–36% interest (varies by state) when the owner redeems. Or acquire property if they don't.
- How to use it: Bid at county tax lien auctions; you pay the delinquent taxes and get a certificate. Owner redeems = you get principal + interest.
- Redemption rate: ~98% of owners redeem—most investors earn interest, not property.
How It Works
The process. Property taxes go unpaid. The county records a lien. It auctions the lien to investors to recover revenue. You bid—in some states you bid on the interest rate (lowest wins), in others you bid on the premium. You pay the delinquent taxes and get a tax lien certificate. The owner has a redemption period—1 to 4 years depending on the state—to pay you back with interest. If they do, you're done. You got your principal plus 10%, 18%, or whatever the state allows. If they don't, you may be able to foreclose and take the property. That's the tax deed path.
Interest rates by state. Florida caps at 18%. Illinois allows up to 36%. Indiana and Georgia: 10%. Connecticut: 18%. Rates are set by statute—you're not negotiating with the owner. The catch: in competitive markets, investors bid down the premium or the effective rate. Institutional money has flooded in; returns have compressed in some counties.
Liens vs deeds. Tax liens = you have a claim. The owner can redeem. Tax deeds = the county sells the property itself at auction. Different states use different systems. Some are lien states (Florida, Illinois, Texas); some are deed states (Georgia, Arizona). Know your state's rules.
Real-World Example
Florida tax lien, 2023.
A homeowner in Tampa fell $2,400 behind on property taxes. The county auctioned the lien. You bought it for $2,400 at 18% annual interest. Florida's redemption period is typically about 22 months. The owner redeemed in 14 months. You got $2,400 plus $504 in interest (14/12 × 18%). That's a 21% return on your money in 14 months. No property to manage, no vacancy, no rehab costs. The other 2% of the time, the owner doesn't redeem—and you're in foreclosure territory, which is a whole different ball game.
Pros & Cons
- Secured by the property—you're ahead of most other creditors.
- Interest rates can be 8–36% depending on state—often higher than cap rate on rentals.
- No property management—you're not a landlord until/unless you foreclose.
- Predictable in lien states with fixed rates—you know what you'll earn if they redeem.
- ~98% redeem—you usually don't get the property. It's an interest play, not an equity play.
- Competitive bidding has driven down returns in hot markets.
- Foreclosure is complex—if they don't redeem, you're in legal territory. Property condition unknown.
- State rules vary wildly—redemption periods, interest caps, foreclosure procedures. You've got to know the local game.
Watch Out
- Redemption risk: Don't count on getting the property. Most liens get redeemed. Model for interest income, not equity.
- Property condition risk: If you foreclose, you might get a tear-down. You didn't inspect it before you bought the lien. Due diligence is limited.
- State rules risk: Each state is different. Redemption period, interest rate, foreclosure process—get it wrong and you lose. Hire local counsel.
- Competition risk: Institutional investors bid aggressively. In some counties, effective returns have dropped. Do the math before you bid.

The Takeaway
Tax liens let you earn interest on delinquent property taxes—often 8–18% or more—without owning the property. You buy the lien at auction; the owner redeems and pays you back with interest. About 98% redeem. If they don't, you may foreclose—that's where tax deeds and property acquisition come in. It's a different strategy than buy-and-hold. Know your state's rules and model for interest, not property.
