Two very different products get sold under the banner of "tax sale," and mixing them up is the most expensive beginner mistake in this market. A tax lien is the debt: you buy the county's claim to the unpaid taxes and earn interest until the owner pays up. A tax deed is the property: the foreclosure already happened, and the county is auctioning the real estate itself. Which one your state sells decides what you walk away with, how long you wait, and what can go wrong.
This explainer covers the split, the state-by-state map, and the redemption clock that runs both systems. For the full pipeline — liens, deeds, repository lists, and land banks, ranked by risk — start with our guide to buying tax-delinquent property.
What you're actually buying
Take the same $4,000 of unpaid taxes on a $60,000 house.
In a lien state, you can buy that $4,000 claim as a certificate. The owner now owes you the money plus interest at a rate set by statute, with the house as collateral. If they redeem, and the large majority do, you get your $4,000 back with interest. You never touch the house, never get keys, never see the inside. Only if the owner fails to pay through the entire redemption period can you foreclose, and that is a separate court process with its own timeline and legal bills.
In a deed state, the county already did the foreclosing. You bid on the house itself, with a minimum bid usually built from the back taxes and sale costs. Win at $4,000 and you own the property (or the county's interest in it): as-is, sight unseen, with the title work still ahead of you.
Same four thousand dollars. One buys a debt that usually turns into an interest check; the other buys a house with strings attached. The auctions themselves — bid-down interest rates, premium bidding, minimum bids — work the same way across both systems, and the pillar guide covers those mechanics in depth, so we won't repeat them here.
Lien states, deed states, hybrid states
Published state lists contradict each other, and not because anyone is sloppy. Hybrid systems defy a single label: Florida and Illinois both run lien sales that end in deeds, so they show up on "lien state" and "deed state" lists alike. Here is how the biggest systems actually work, verified against state statutes and county tax offices as of mid-2026:
| State | System | The clock |
|---|---|---|
| Arizona | Lien | Rates start at 16% and bid down; foreclosure possible only after a 3-year redemption window |
| Florida | Lien, then deed | Certificates cap at 18%, bid down; after 2 years the holder can trigger a public deed auction |
| Illinois | Lien | Penalty rate bid down at the annual sale; owners get roughly 2.5 years to redeem before a court can issue a deed |
| New Jersey | Lien | Rates cap at 18%; a private certificate holder waits 2 years before filing to foreclose |
| California | Deed | Sold only after 5+ years (3 for vacant lots and commercial property) of default; the right to redeem ends before the auction starts |
| Michigan | Deed | County treasurers foreclose after roughly 3 years of delinquency, then auction deeds; no lien sales to investors |
| New York | Deed (mostly) | Most counties foreclose and auction deeds; Nassau and Suffolk sell liens, and New York City is winding down its lien-sale program in favor of a city land bank |
| Texas | Redeemable deed | You take the deed home, but the former owner can buy it back: 180 days for most property, 2 years for homesteads and agricultural land, plus a 25% premium in year one (50% in year two on homesteads and agricultural land) |
| Georgia | Redeemable deed | The former owner keeps a right to reclaim for at least a year after the sale, at a premium |
| Ohio | Both | Larger counties can sell lien certificates; others foreclose straight to deed auctions |
Treat every row as a starting point, not gospel. Practice varies county by county even inside one state, and these statutes have been unusually busy since the Supreme Court's 2023 Tyler v. Hennepin County decision forced many states to rewrite how surplus sale proceeds are handled. Before you bid anywhere, confirm the current rules with that county's treasurer or tax collector. Five minutes on the phone is the cheapest diligence you will ever do.
Redemption periods: the clock that runs everything
Both systems revolve around a redemption clock. The difference is which side of the sale it runs on.
In lien states, the clock starts after you buy. You hold a certificate and wait. The owner (or, just as often, their mortgage lender protecting its own position) can pay the debt at any point in the window: months in some states, years in others. Redemption isn't a failure mode; it's the base case, and it's your exit with interest. The catch is that your cash is locked up the whole time, and in many states you must keep paying the new taxes that come due to protect your position.
In deed states, the clock mostly runs before the sale. California is the clean example: property must sit tax-defaulted for five-plus years before the county can sell it, and the former owner's right to redeem expires before the auction opens, so the deed you win is final. Redeemable-deed states like Texas and Georgia sit in between: the clock survives the sale, and you hold the deed in limbo until it expires. A Texas owner who redeems in the first year pays you a 25% premium, which is a fine return, but you'd be foolish to renovate a house someone can still take back.
The risks buyers miss
On the lien side:
- Most liens never convert. If your goal is a house, you have picked the slowest, least certain path to one. Our guide to how to buy tax lien homes covers the foreclosure leg honestly, including how often it doesn't happen.
- Foreclosure costs are yours. Attorney fees, notice requirements, and court timelines can exceed the value of a small lien on a marginal parcel.
- Competition eats the yield. Bid-down auctions push rates toward zero on the good properties, and premium bids come straight out of your return.
On the deed side:
- The title is not clean. Old liens, unnotified heirs, and procedural defects can survive the sale. Plan on a quiet-title action before any insurer will touch it.
- Some claims survive outright. Certain government and municipal liens ride through the sale, and the IRS holds a post-sale redemption right when a federal tax lien is attached.
- Occupants are your problem. If someone lives there, a formal eviction through the courts is your first act as owner.
The shortcut at the end of the pipeline
Everything above is the raw end of the tax-delinquency pipeline: cheap because the risk still belongs to you. The far end is the land bank, where the same tax-foreclosed property comes out with title cleared, a posted price, and an application instead of a gavel. You trade the rock-bottom bid for a deal a normal buyer can actually close. Our land bank vs. tax sale vs. foreclosure comparison makes the full case, and the inventory itself is live on our cheapest-houses page: tax-delinquent property that already made it through the machine.
