Do you ever wonder how a county ends up owning land or a house, and then selling it to someone like you? In Ozaukee County, Wisconsin, that happens through something called a tax deed sale. Below is a breakdown of how it works, who to contact, and the steps you need to take before you bid.

What Is a Tax Deed?

When a property owner does not pay real estate taxes, the debt becomes delinquent. If the taxes stay unpaid long enough, the county can take legal title to the property. This is called a tax deed. The county then sells these properties to the public to recover the unpaid taxes.

The Basics: How Does Ozaukee County Get These Properties?

Property owners are required to pay real estate taxes every year. When someone stops paying and the debt sits unpaid for long enough, Ozaukee County has the legal right to take that property. Once the county holds the title, it does not keep the land forever. Instead, it lists the property for sale so the public can buy it and the county can recover what it is owed.

This setup is different from states that sell tax lien certificates. Wisconsin skips that step entirely. There is no investor buying debt and collecting interest while they wait. The county becomes the owner outright, then turns around and sells the property itself. That full ownership transfer is exactly what makes it a tax deed, rather than a lien.

Who Manages This in Ozaukee County?

The Ozaukee County Treasurer’s Office oversees the whole process, from collecting unpaid taxes to publishing sale notices. Sandi Tretow currently holds the Treasurer position. Her office also handles day-to-day tax payments, tax bill questions, and assessment records for the county, so the same team you’d contact about a routine tax bill is the one running the tax deed sales.

Before any property goes up for sale, state law requires the county to publish the appraised value and sale terms so buyers know what they are working with ahead of time.

Step-by-Step: From Unpaid Taxes to a Finished Sale

Step	What Takes Place
1	The property owner stops paying real estate taxes
2	Ozaukee County moves through the legal steps to claim the title
3	The county officially becomes the legal owner of the parcel
4	An appraisal is ordered to set a fair market value
5	A Notice of Appraisal and Sale gets published on the county site
6	Bids or offers come in under the terms spelled out in the notice
7	The winning buyer pays, and the deed gets recorded

One thing to keep in mind: Ozaukee County does not hold sales on a fixed schedule. A notice only goes up when the county actually has tax-deeded property ready to sell. That means timing is everything if you’re hoping to bid.

How to Actually Bid on a Property

Here’s a simple walkthrough if you want to take part in a sale.

1. Visit the Treasurer’s Foreclosure Property page and look for an active Notice of Appraisal and Sale.
2. Read the notice from top to bottom. It spells out the bid deadline, the appraised value, and anything unusual about the property.
3. Dig into the parcel’s history using the county’s tax and property search tools. You want to know past ownership and assessed value.
4. Contact the Register of Deeds to check for old liens or claims that could still be tied to the land.
5. Call the local municipality (city, village, or town) to confirm what the property can legally be used for.
6. Submit your bid before the stated cutoff. Late submissions typically will not count.
7. If you win, pay according to the terms, then record your deed with the Register of Deeds.

Don’t Skip the Homework

Every tax deed property sells as is. Ozaukee County will not repair anything, and there’s no promise about the condition of the building or the land itself. Before you commit to a bid, take these precautions:

• Pull the parcel’s full tax and ownership history online.
• Check Register of Deeds records for any unresolved liens.
• Drive by and view the exterior in person, since interior access is rarely allowed.
• Confirm zoning restrictions with the local municipality.
• Set aside extra funds in case repairs or cleanup are needed later.

Common Questions (FAQ)

How is a tax deed different from a tax lien?

A tax lien means someone buys the debt and waits for interest. A tax deed means the county already owns the property outright before selling it to you. Ozaukee County only does tax deeds.

How often does Ozaukee County hold these sales?

There’s no set calendar. A sale only opens once the county has tax-deeded property ready to list, so check the Treasurer’s page often or sign up for alerts.

Where do I check for open listings?

The Foreclosure Property For Sale section of the Ozaukee County website is the place to look. You can also sign up there for notifications about new sales.

Can I walk through the inside of a property first?

Usually not. Since properties sell as is, most sales only allow you to view the outside.

What if the property has old debts attached to it?

Search Register of Deeds records ahead of time. This helps you spot liens or claims before you bid, not after.

Who should I call with questions?

The Ozaukee County Treasurer’s Office handles all questions about active or upcoming tax deed sales.
