Tax deed vs tax lien states

Two states can call it the same thing — a tax sale — and sell you completely different assets.

In one you are buying a debt that pays interest. In the other you are buying a house. The strategies, the capital requirements, the timelines and the risks share almost nothing, and confusing them is the most common error in this corner of real estate.

The core difference#

A tax lien sale sells the debt. The county needs its tax revenue now, so it sells a certificate representing the unpaid taxes. You pay the county, and the owner now owes you rather than the county — plus statutory interest. When they pay, you get your money and your interest. You never touch the property.

Only if nobody redeems within the statutory period do you gain the right to pursue title, and in most states that means filing and funding a separate foreclosure action.

A tax deed sale sells the property. The county has already gone through its delinquency process, taken or is taking title, and is now selling the parcel. You bid, you win, and title passes to you at the sale or shortly after. Many deed states still give the former owner a redemption window afterwards, but you hold the property in the meantime.

The asymmetry most people miss: in a lien state, getting the property is usually the bad outcome. Liens on desirable property get redeemed, because the owner or their mortgage lender pays to protect it. The liens that go unredeemed are the ones on land nobody wants — a landlocked strip, a contaminated lot, a condemned structure with demolition costs attached. You end up owning it and paying to hold it.

Which states do which#

Verify locally before bidding. Several states run both systems depending on the county, and a few switch depending on how long the taxes have been delinquent. County practice varies within states that permit both.

States using both, or hybrid systems#

Redemption after a tax sale is the part that catches people#

Redemption after a tax sale is a different rule from redemption after a mortgage foreclosure, and the two are frequently confused by investors who learned one state's foreclosure rules and assumed they transferred.

Texas is the clearest illustration. No redemption after a mortgage foreclosure at all — the auction is final. But a homestead or agricultural property sold at a tax sale carries a two-year redemption, and other property six months. An investor who knows Texas foreclosure and bids at a Texas tax sale has the timeline wrong by two years.

Georgia grants nothing after a non-judicial mortgage foreclosure but gives a full year after a tax sale, with a 20% penalty payable on redemption.

Louisiana runs a three-year redemption on tax sales.

Wyoming gives around three months after a mortgage foreclosure and four years after a tax lien sale.

The pattern is consistent: tax redemption periods are longer, because the policy question is different. Losing a home to an unpaid mortgage is a contract failing. Losing it over a few thousand dollars of tax is something legislatures have generally wanted to make hard.

Minnesota: forfeiture rather than a lien sale#

Minnesota does not sell tax liens, and its deed process has its own shape worth understanding because it is a common source of confusion.

Unpaid taxes lead to a judgment, then a statutory period, then forfeiture of the parcel to the State of Minnesota. The county then offers forfeited land for sale under Minn. Stat. ch. 282, on its own schedule, with rules about who may bid and what happens to any proceeds.

There is no certificate to buy and no interest to earn. The property simply stops being the owner's and becomes the state's, and is then sold.

Govire tracks this alongside mortgage foreclosure across Minnesota counties, and the two behave differently enough that they are held as separate signals: tax forfeiture runs on a multi-year clock from judgment, mortgage foreclosure on a six-month redemption from the sheriff's sale. Mixing them produces nonsense — pooling both into one survival analysis moved a published timing figure from 18.8% to 33.0% at one year once the tax rows were removed, because forfeiture windows are roughly six times longer and never resolve the same way.

Tyler v. Hennepin County changed the economics#

In 2023 the Supreme Court held in Tyler v. Hennepin County that a government keeping equity beyond the tax debt is an unconstitutional taking under the Fifth Amendment. Geraldine Tyler owed about $15,000 in taxes and penalties on a condominium the county sold for $40,000, and the county kept all of it.

States that previously absorbed the full value of a forfeited property have had to change. Surplus claim processes now exist in many of them, and several state legislatures rewrote their forfeiture statutes.

Two consequences for anyone bidding:

The arithmetic shifted. Where a county previously kept the whole sale price, the surplus above the debt now belongs to the former owner. That changes what counties net, and in some states how aggressively they pursue forfeiture at all.

Unclaimed surplus is now a live niche. Former owners frequently do not know they are owed anything, and a claim process exists that many never use. Whether recovering that on someone's behalf is a service or a form of predation depends entirely on the fee charged, and several states have legislated on exactly that question.

What survives a tax sale#

A property tax lien is senior to almost everything, which is why a completed tax deed can extinguish a mortgage that a foreclosure auction would have left standing.

That sounds like an advantage. In practice it rarely comes up on valuable property, and the reason matters:

Mortgage lenders watch tax delinquency closely. A lender whose security could be wiped out by a few thousand dollars of unpaid tax pays the tax. Escrow accounts exist largely for this. Property that reaches a tax sale with real equity and a mortgage still attached is unusual, and it usually means nobody is watching.

Which raises the question worth asking before every tax sale bid: if this property has value, why has no lender protected it? The usual answers are that there is no mortgage, or that the owner has died with no probate opened — the tangled-title problem, where heirs may not know they own it and nobody has standing to pay the bill.

That second case is common, and it is the one where a tax sale purchase can be both a good deal and a family losing an inheritance they did not know they had.

What still survives#

Not everything is cleared:

• Federal tax liens, usually with a statutory right for the IRS to redeem
• Municipal assessments and code enforcement charges in many states
• Easements and restrictive covenants, which are property rights rather than debts
• Environmental liability, which follows the land

And in most tax deed states you receive a tax deed rather than a warranty deed, which conveys whatever interest the county had and nothing more. Title insurers are frequently unwilling to insure a tax deed until a quiet title action has been completed — an additional cost and delay most first-time buyers do not budget for.

How the auction itself works, and why the advertised rate is fiction#

The statutory interest rate is the number every guide quotes. It is almost never what a competitive certificate returns, because of how the auctions run.

Bid-down interest. Investors compete by accepting a lower rate. Arizona's statutory maximum is 16%; contested parcels routinely clear in low single digits. Florida's ceiling is 18% and heavily bid parcels reach a fraction of one percent. The advertised rate is a ceiling, not an expectation.

Bid-down ownership. Iowa and a few others run an unusual variant where investors bid down the percentage of the property the certificate would convey if it went unredeemed. You might end up entitled to a small undivided share rather than the whole parcel — a co-ownership problem rather than an asset.

Premium bidding. New Jersey and others let investors bid a premium above the lien amount once the rate reaches zero. The premium is generally not returned on redemption, so the effective yield can be negative if the lien redeems quickly.

Rotational or random selection. Some counties assign liens in rotation or by lot rather than by competitive bid, which produces the statutory rate but gives no control over which parcels you receive.

The practical consequence: two investors in the same state can experience completely different returns depending on the auction mechanism and how contested the sale is. Institutional buyers dominate the large online sales in Florida, Arizona and New Jersey, bidding at scale with automated systems. The advertised rate on a state summary page tells you almost nothing about what is achievable there.

What actually happens to unredeemed liens#

The redemption rate on tax liens is high — most guides say so and it is true. What they rarely explain is the composition of what does not redeem.

Redeemed liens are the normal case because someone has an incentive to pay: the owner wants their home, the mortgage lender is protecting its security, or an heir is protecting an inheritance.

Unredeemed liens cluster on parcels where nobody has that incentive:

• Landlocked or unbuildable parcels — slivers, remnants of road widening, strips with no access
• Contaminated or remediation-liable land, where the tax debt is trivial next to the cleanup cost
• Structures with demolition orders, where the city will bill the owner for the teardown
• Properties with tangled title, where heirs exist but nobody has standing to act
• Genuinely abandoned property in declining markets, where the land is worth less than the accumulated taxes

Only the fourth category is a good outcome for an investor, and it is the one that raises a real question about who loses when it works.

That is the shape of tax lien investing that the marketing does not describe: the strategy succeeds when it earns interest, and the times it delivers a property are disproportionately the times something is wrong with the property — or with someone's ability to protect it.

Which system suits which investor#

Tax liens suit a fixed-income mindset. You want a statutory rate, a senior position, and you are content that the property never becomes yours. Capital is tied up for the redemption period and returns are eroded by competitive bidding — bid-down auctions in Florida and Arizona routinely take advertised rates down to low single digits.

Tax deeds suit a property mindset. You are buying real estate, usually without inspection, often needing a quiet title action, and sometimes with a redemption window during which the former owner can take it back.

Neither suits someone expecting to buy houses for the price of the taxes. That outcome exists and it is rare. Competitive markets bid liens down and deeds up, and the properties that go cheap usually go cheap for a reason visible only after you own them.

Before you bid#

1. Establish which system that county runs, not just the state.
2. Find the redemption period for a tax sale specifically — not the mortgage foreclosure rule.
3. Work out what taking title actually requires. In lien states it usually means funding a foreclosure.
4. Ask whether title will be insurable, and price a quiet title action if not.
5. Check what survives — federal liens, assessments, environmental.
6. Look at the property. Exterior at minimum. Unredeemed liens cluster on parcels nobody wants.
7. Ask why no lender protected it. The answer is usually no mortgage, or a death with no probate.
8. Price the wait. Multi-year redemption periods are capital you cannot use.
