What sellers must disclose in Wisconsin

How disclosure works
Statutory form required
Official form
Real Estate Condition Report
Form legally required
Yes

The legal standard: Under Wis. Stat. ch. 709, owners transferring 1-4 unit residential property must furnish a completed Real Estate Condition Report disclosing defects they are aware of, no later than 10 days after acceptance of the contract.

Wisconsin sellers must give you the statutory Real Estate Condition Report, disclosing known defects — conditions with a significant adverse effect on value, health/safety, or expected life of the premises. Note the timing trap: the report is due within 10 days AFTER your offer is accepted, not before you bid. Fiduciaries (personal representatives, trustees, court-supervised conservators) who never occupied the property are exempt.

Our research did not confirm whether Wisconsin law specifically requires flood-risk disclosure. Ask the seller directly, in writing, whether the home has ever flooded — and check the official flood map yourself (next section).

Property taxes after you buy in Wisconsin

Reassessment cycle
annual assessment — each year's assessment is new, and municipalities must bring major classes within 10% of full value at least once in a 5-year period (Wis. Stat. 70.05(5)(b)), with full revaluations as needed
Does buying reset the taxable value?
No

Your bill follows the municipality's annual assessment at full value, not the seller's bill and not a price locked in by your sale. Because a full revaluation can land in any given year, a home that has been under-assessed relative to its neighbors can see a sharp bill increase after revaluation regardless of when it sold.

Homestead: Wisconsin has no general homestead value exemption; the Homestead Credit is a low-income income-tax credit for homeowners and renters, and bill credits include the school levy, First Dollar and Lottery and Gaming credits.

Check the Wisconsin sex-offender registry

Wisconsin Sex Offender Registry is run by Wisconsin Department of Corrections. Search it by the home's address before you offer — and search again before closing, because registry data changes as people move.

You can also search every state at once through the federal National Sex Offender Public Website (NSOPW). A CurbFacts report shows the registry count for the home's ZIP — the same public data, organized for the decision.

Flood maps in Wisconsin

The only flood map that decides a lender's insurance requirement is FEMA's — the National Flood Hazard Layer behind the official FEMA flood map viewer. Listing sites license private models that can and do disagree with it; when they conflict, the FEMA map is the one your lender and insurer use.

Check the exact parcel, not the ZIP code: flood-zone boundaries cut through streets, and two houses side by side can sit in different zones.

Buyer traps specific to Wisconsin

You commit before you see the report

Chapter 709 gives the owner until 10 days after contract acceptance to furnish the report; a buyer who does not receive a complete report in that window may rescind only within 2 business days after the 10-day period ends (Wis. Stat. 709.02) — calendar that deadline at signing.
