Short answer: Unpaid property taxes create a lien that outranks almost everything else, including the mortgage. That priority is why tax delinquency eventually forces a sale, and why investors pay attention to it.
- The tax lien is usually senior to the mortgage. That is the whole reason this works.
- Two systems: tax lien states sell the debt, tax deed states sell the property.
- Redemption periods give the owner time to pay and get it back. Length varies enormously.
- Delinquency is a distress signal long before any sale happens.
Property taxes fund the county, so counties are given strong tools to collect them. The strongest is priority: a property tax lien generally sits ahead of the mortgage, which means it can wipe out a lender’s position if it runs to completion.
That single fact explains everything else on this page.

The timeline, in general shape
- Due date passes. The amount becomes delinquent and interest and penalties begin to accrue, often at rates well above market.
- Delinquency is published. Most states require a public list, which is where investor lists originate.
- A lien attaches or is certified, depending on the state.
- Sale. Either the lien is auctioned to investors, or the property itself is auctioned, depending on which system your state uses.
- Redemption period. The owner can usually still pay everything owed plus interest and keep the property.
- Foreclosure or deed issuance. If redemption expires, ownership moves.
Every stage above varies by state, and several vary by county within a state. Treat this as the shape rather than the schedule.
Tax lien states and tax deed states
| Tax lien states | Tax deed states | |
|---|---|---|
| What is sold | The tax debt, as a certificate | The property itself |
| What you get | The right to be repaid with interest | Title, subject to the sale’s terms |
| Usual outcome | Owner redeems, you earn interest | You own a property |
| If nobody redeems | You may apply to foreclose the lien | Already done |
| Capital needed | Often small, the tax amount only | Full purchase price at auction |
Some states operate hybrids, such as redeemable deeds where you buy the deed but the owner retains a redemption right. Confirm your own state’s mechanism before assuming either model applies.
A tax lien certificate is an investment in a debt, not a shortcut to owning property cheaply. In most cases the owner redeems and you receive interest, which is the expected outcome rather than a disappointment. Anyone promising houses for a few hundred dollars in back taxes is describing the rare exception.
Why this matters if you buy houses
For a wholesaler the sale itself is often less interesting than the signal. An owner several years delinquent is telling you something: the property may be vacant, inherited, or simply beyond what they can carry.
- Long delinquency correlates with absentee and heir situations, which are among the better lists in the business.
- The lien is a number you can pay off at closing, so it is a solvable problem rather than a deal killer.
- The published list is free, because publication is usually required by statute.
- There is a real deadline, which gives the conversation a reason to happen now.
Cross reference the delinquency list against the assessor for owners whose mailing address differs from the property address, and against probate filings. That intersection is a much smaller and much better list than either source alone.
What to be careful about
- Other liens survive differently depending on the state and the mechanism. Municipal, federal and some special assessments can behave unexpectedly.
- Federal tax liens have their own redemption rules that can outlast the sale.
- Auction properties are usually sold as is, frequently without the right to inspect, and sometimes still occupied.
- Title insurance can be difficult to obtain on a tax sale property until a quiet title action is completed.
Frequently asked questions
What happens if you do not pay property taxes?
Interest and penalties accrue, the delinquency is published, and eventually the county either sells a lien on the debt or sells the property itself, depending on your state. The owner usually has a redemption period before ownership finally moves.
Does a tax lien beat a mortgage?
Property tax liens generally have priority over mortgages, which is why tax delinquency can extinguish a lender’s position. Specifics vary by state, so confirm locally.
What is the difference between a tax lien and a tax deed?
In a tax lien state you buy the debt and earn interest when the owner redeems. In a tax deed state the property itself is sold. Some states use hybrids such as redeemable deeds.
Can I really buy a house for the back taxes?
Rarely. In lien states the usual outcome is that the owner redeems and you earn interest. In deed states competitive bidding normally pushes the price well above the tax owed.
How long is the redemption period?
It varies widely by state, from months to several years, and can differ by property type. Check your state’s statute rather than a general figure.
Is the delinquent tax list public?
In most states publication is required, so the list is public and usually free from the county treasurer or tax collector.
