Tax lien vs. tax deed investing: how counties sell debt and dirt
Tax liens pay statutory interest of 8–36%; tax deeds sell the property itself, sometimes for the back taxes alone. How each system works, which states run which, and the redemption rules that decide everything.
What's the difference between a tax lien and a tax deed? When property taxes go unpaid, every county eventually sells something — and each state picks which. Tax lien states sell the debt: you pay the owner's taxes and earn statutory interest (8–36% depending on state) until they redeem, with a claim on the property if they never do. Tax deed states sell the property: an auction transfers ownership to satisfy the taxes, occasionally for little more than the delinquent bill — the cheapest acquisitions in all of real estate. Liens are a yield strategy that belongs beside notes and lending; deeds are an acquisition channel that belongs beside the other distressed auctions. Most investors conflate them; the systems share nothing but the courthouse.
Tax liens: being the county's collector
The mechanics: the county auctions a certificate for the delinquent amount; you pay it; the owner now owes you the taxes plus statutory interest; when they redeem (pay up), the county sends you principal plus interest. If they never redeem within the statutory window (6 months–3 years by state), you can foreclose and take the property — which happens rarely, because owners, heirs, or mortgage lenders (who hate losing collateral to a tax sale) almost always pay.
The honest yield math: headline rates — Florida 18%, Arizona 16%, Illinois up to 36% — get competed down at auction. Florida's bid-down system routinely lands institutional money at 0.25%; the real returns live where institutions don't: small counties, odd parcels, over-the-counter lists of unsold certificates at full statutory rates. Diligence still matters — a lien on a worthless strip of drainage ditch earns nothing when nobody redeems and the "collateral" is a liability. Rule: never buy a lien on a property you haven't valued, because ~5% of the time, the lien is the property.
| Tax lien certificate | Tax deed purchase | |
|---|---|---|
| You buy | The debt + statutory interest claim | The property itself, at auction |
| Typical outcome | Redemption: principal + interest in months to years | Ownership — after any redemption period runs |
| Capital per position | Hundreds to a few thousand dollars | Thousands to market-adjacent prices on good parcels |
| Return profile | 8–36% statutory, bid down by competition | Deep-discount equity — with title-clearing and condition risk |
| Best suited to | Yield investors, IRAs, patience | Rehabbers, land investors, and flippers who do title homework |
| Example states | FL, AZ, IL, NJ, CO (liens) | TX, GA, CA, WA (deeds); TX/GA add redemption penalties — hybrids |
Tax deeds: the cheapest doors in America
Deed auctions transfer ownership — and the discounts are real because the problems are: no interior access before sale, occupants who may still live there, junk title (a tax deed extinguishes most liens but arrives insurable-title-free — you'll quiet title or use a specialist service before selling with insurance), and redemption tails in hybrid states. Texas and Georgia are the famous hybrids: the owner can redeem after the sale by paying you a statutory penalty — 25% in Texas within six months, 20% in Georgia within a year — which means you either keep a deeply discounted property or earn a fat short-term return for being briefly inconvenienced. That's the best risk-shape in the space, and why competition there is fierce.
The workflow that separates professionals from donors:
- 01Pull the sale list earlyCounties publish weeks ahead. Most items are junk — landlocked slivers, contaminated lots, condemned shells. The list is a haystack by design.
- 02Title-search every candidateIRS liens and some municipal claims can survive; a mortgage lender's presence predicts redemption. An hour of records per parcel is the entry fee.
- 03Drive and valueCurbside condition, occupancy signals, honest as-is value. You're bidding blind on the inside — price like it.
- 04Set maximum bids, then obey themAuctions manufacture adrenaline. The max bid was made by the sober you; the bidding you is not consulted.
- 05Clear title, then exitQuiet-title action or tax-title insurance service, then sell, rent, or hold. Budget $2–5k and a few months for the clearing — it's a line item, not a surprise.
Where tax sales fit in the plan
Liens are a Years 1+ yield sleeve: small positions, IRA-friendly (interest compounds untaxed in a self-directed account), and a forced education in county records. Deeds are a Years 2–6 acquisition channel for investors who'll do the diligence others skip — feeding flips, land inventory, and rentals at bases the MLS never offers. Both reward the same temperament: research-heavy, unglamorous, patient — the off-market ethos at its purest.
Frequently asked questions
+How does tax lien investing work?
You pay a delinquent owner's property taxes at a county auction and receive a certificate entitling you to repayment plus statutory interest (8–36% by state). When the owner redeems — as 95%+ eventually do — you collect principal and interest. If they never redeem within the statutory period, you can foreclose on the property. It's a yield investment with a rare acquisition lottery attached.
+Can you really buy a house for back taxes?
In tax deed states, occasionally yes — auctions open at the delinquent amount, and unglamorous properties in thin-attendance counties sometimes sell near it. The realistic picture: competitive parcels get bid toward (discounted) market value, the title needs quieting before resale, and condition is unknown until you own it. The bargains are real; they're paid for in research volume.
+What states are tax lien states vs. tax deed states?
Roughly half each, plus hybrids: lien states include Florida, Arizona, Illinois, New Jersey, and Colorado; deed states include California, Washington, and most of the west; Texas and Georgia are redeemable-deed hybrids where post-sale redemption pays you a statutory penalty (25% in TX within six months, 20% in GA). Each state's rules differ enough that you learn one state at a time.
+What are the risks of tax deed investing?
Buying blind (no interior inspection), occupants requiring formal possession processes, surviving liens (IRS and some municipal claims), redemption tails in hybrid states, and uninsurable title until a quiet-title action (~$2–5k and a few months). Every risk is priced into the discount and managed by pre-auction diligence — the losses in this space go to bidders who skipped the title search.
+Are tax liens good for an IRA?
They're a natural fit: lien interest is ordinary income (taxed at your top rate in a taxable account) and positions are small, making them ideal for a self-directed IRA or Solo 401(k) where the interest compounds untaxed. The administrative note: the IRA must fund purchases and receive redemptions directly — you can't touch the money personally without a prohibited-transaction problem.
The rest of the courthouse channels: foreclosure auctions, REO, and off-market channels. The yield family: note investing and private lending.
