Plain English
What is a tax lien?
A tax lien is a legal claim a county puts on a property when the owner has not paid their property taxes. The county can sell that claim to an investor. Buying it does not make you the owner of the house.
Prepared by the TaxLienSimple Research Team. Reviewed October 4, 2026. The figures on this page come from inventory we hold and refresh nightly, and each one names the county it came from. See our verification policy.
What does the county actually sell you?
It sells you the debt, not the building. When somebody stops paying property tax, the county still needs that money to run schools and fire services. So it attaches a claim to the property and then sells the claim to whoever will hand over the cash today.
You pay the county the unpaid tax. In exchange you get the right to be repaid that amount plus interest when the owner settles up. The owner keeps living there. They keep the title. Nothing about their day changes except who they owe.
So do I get the house or not?
Almost always not. In most cases the owner pays, you get your money back with interest, and that is the end of it. That is the normal outcome and it is the one the system is designed to produce.
If the owner never pays, there is a process that can eventually end with you taking the property. It takes years, it costs legal money, and it is the exception. Anyone who tells you tax liens are a way to buy houses cheaply is describing the rare ending as if it were the usual one.
How do I make money from it?
From interest set by state law, not by negotiation. Florida law caps it at 18 percent a year. Arizona caps it at 16 percent. Iowa runs at 2 percent a month. The county does not haggle: the rate is whatever the statute says.
There is a catch, and it is the main one. At a busy auction, investors compete by accepting a lower rate, so the published 18 percent can be bid down to low single digits. The full rate usually survives only on liens nobody bid on, which the county then sells afterwards at the statutory maximum.
Why would a lien go unsold at the auction?
Because the parcel is unappealing to bidders. It is often vacant land, a strip too narrow to build on, a mobile home, or a lot with an awkward title. The lien is still valid and the interest rate is still real. The property behind it is just not something people fight over.
That is worth saying plainly because it cuts both ways. Nobody bidding is why the rate stays high. It is also a signal that you should look hard at what you are attaching your money to.
How much money do I need to start?
Less than most people assume. Looking at live county-held inventory today, there are liens in Lake County, Florida at $200 and in Palm Beach County at a little over $200. These are not promotional figures, they are what the county is asking.
Small does not mean safe. A 200 dollar lien on a sliver of land you can never sell is still $200 you may not see again quickly. The size of the cheque is not the risk.
Is a property tax lien the same as a federal tax lien?
No, and people mix these up constantly. A property tax lien is filed by a county over unpaid property tax and it can be sold to an investor. A federal tax lien is filed by the IRS over unpaid income tax, and you cannot buy it.
If you arrived here looking for the IRS kind, this page is not it. Everything on this site is the county kind.
Putting real numbers on it
A real one, with the figures broken out
- 3333 Brothers Pl SE, Washington DC. The District bid this lien off to itself in the August 2026 sale, which means nobody else took it.
- Unpaid property tax: $434.37
- Penalties, interest and sale fees: $576.62
- Total the lien was bid off at: $1,010.99
Look at the split. More than half of what you pay is penalty and interest the owner racked up, not tax. That is normal, and it is why the number on a lien list is usually bigger than the tax bill it started as. Washington DC pays 1.5 percent a month on redemption under its own 2026 rules.
What goes wrong
- You expect a house and get a cheque. Most liens redeem. If your plan needs the property, tax liens are the wrong instrument and a tax deed is closer to what you want.
- You buy a parcel you cannot inspect. A list gives you an address and a figure. It does not tell you the lot is landlocked, under water, or three feet wide.
- You forget the later taxes. In many states the owner keeps missing payments, and you have to pay those too or risk your position. That is more capital going in after the first cheque.
- You assume the advertised rate. At a competitive auction it gets bid down. The statutory maximum mostly survives on inventory nobody wanted.
- You treat a cheap lien as a cheap risk. A 200 dollar lien that never redeems on land nobody will buy is a total loss of $200 plus whatever you spent looking into it.

Frequently asked questions
Does buying a tax lien give me ownership of the property?
No. It gives you the county's claim for the unpaid tax, plus the right to be repaid with statutory interest. Ownership only comes into play if the owner never redeems and you complete a separate foreclosure process, which takes years and is the exception rather than the rule.
What happens if the owner never pays?
After a waiting period set by state law you can start the process to take title. It involves legal filings, notice to everyone with an interest in the property, and cost. Some investors do end up with property this way. Plan for redemption and treat the property as the unlikely case.
How much does a tax lien cost?
Whatever is owed on that parcel, which can be a couple of hundred dollars or tens of thousands. In live county-held inventory today the cheapest Florida liens start around $200 and a single Washington DC lien runs past $700,000.
Is a tax lien the same thing as a tax deed?
No. A tax lien is the debt. A tax deed is the property itself, sold because the taxes went unpaid. Different states use one system or the other, and a few use a hybrid where you get a deed but the former owner can still buy it back.
Can I buy a tax lien without going to an auction?
Yes, in many places. Liens that draw no bid at the annual sale are held by the county and sold afterwards, first come first served, usually at the full statutory rate. That is the inventory this site tracks.
Who pays me back, the owner or the county?
You are paid through the county. The owner settles with the county's office, and the county passes on your money plus the interest that accrued. You are not chasing the homeowner for payment yourself.
