Wisconsin property data

Wisconsin is a little different. Deeds are recorded by the county, but property is assessed by each city, village and town, so assessment records come from the municipality. Here's what's public, what's hard to get, and what Deedplat puts on one map.

What you can get in Wisconsin

Wisconsin makes most property records public, including what each property sold for. The catch is that every county keeps them differently.

Public everywhere

Every county has these, and Deedplat loads them all.

  • Owners and mailing addressesFrom the local assessor for each city, village and town, certified by the Department of Revenue
  • Sale pricesEvery sale needs a Wisconsin Real Estate Transfer Return that reports the price, and the Department of Revenue runs a public property sales search built from those returns.
  • Deeds and mortgagesRegister of Deeds in each county
  • Assessed valuesEach municipality must bring its values within 10% of full value at least once every five years, so the schedule varies by municipality.
  • Tax sale listsRun county by county
  • Foreclosure filings and salesFiled in court, so they're public early
  • Lot linesCounty parcel maps

Depends on the town

Cities, villages and towns keep assessment rolls, building permits and code enforcement cases, and those records are covered by the Wisconsin Public Records Law.

  • Code violations and condemnations
  • Building permits
  • Rental registration and inspections
  • Zoning maps and ordinances
  • Water and sewer liens

Not public

What no office will hand over, so you know where the line is.

  • Owner phone numbers and emails
  • Rents and leases
  • Active listingsThose live in the MLS
  • Mortgage balancesThe original loan amount is recorded; what's left is not

How property changes hands here

Distressed property reaches the market through a few channels, and they differ by county.

Tax sales

Wisconsin does not sell tax liens to investors. The county treasurer issues a tax certificate to the county each September, and if taxes are still unpaid two years later the county can take the property through a court foreclosure, giving owners at least 8 more weeks to redeem. The county then sells the property, often by online auction, and under a 2024 law any surplus after taxes and costs goes back to the former owner.

Foreclosure goes through the courts

All mortgage foreclosures go through the courts, and the county sheriff sells the property at the courthouse, another public place or online. The owner has a redemption period before the sale, and the court must confirm the sale before the sheriff's deed is recorded.

Land banks

Wisconsin has no general land bank law; counties take and resell tax-foreclosed property themselves.

Transfer tax

The state real estate transfer fee is $3 per $1,000 of value (0.3%), collected by the Register of Deeds.

Worth knowing

Redemption periods after a mortgage foreclosure judgment are shorter for loans signed on or after April 27, 2016: 3 months if the lender waives a deficiency, or 6 months if it does not, compared with 6 or 12 months for older loans.

Worth knowing

Investors cannot buy tax liens in Wisconsin, so tax-distressed property reaches the market only after the county takes title and sells it.

Questions

Are property sale prices public in Wisconsin?

Yes. Each sale requires a Real Estate Transfer Return that reports the price, and the Department of Revenue offers a public property sales search based on those returns.

How do tax sales work in Wisconsin?

There are no tax lien sales to investors. The county holds a tax certificate, and after two years of unpaid taxes it can foreclose through the court, with at least 8 weeks for owners to redeem. The county then sells the property, and any surplus goes back to the former owner.

Where are deeds and mortgages recorded in Wisconsin?

With the Register of Deeds in the county where the property sits.

How often are Wisconsin properties reassessed?

It depends on the city, village or town. Each must bring its values within 10% of full value at least once every five years, and many revalue more often.

Is foreclosure judicial in Wisconsin?

Yes. Every mortgage foreclosure goes through the courts. The county sheriff holds the sale after the redemption period, and a judge must confirm it before the deed is recorded.

Can I get records Deedplat doesn't have?

Yes. The Wisconsin Public Records Law lets anyone request records from state agencies, counties and municipalities, such as permits or code enforcement files. We file those requests for you, clean up the results and add them to your map.
