FSBO Wisconsin Disclosure Requirements for Sellers

$1,200 is the average cost Wisconsin sellers spend on mandatory disclosures when they list without an agent. If you miss a form, the buyer can back out or demand a price reduction, and you could face a lawsuit. Below is the exact list of disclosures you must provide, where to get each form, and how to stay compliant while you decide between FSBO, flat‑fee MLS, or using Sellable’s AI‑driven listing desk.


What Wisconsin Sellers Must Disclose (40‑60 words)

In Wisconsin you must give the buyer a written Seller’s Property Disclosure Statement (SPDS), a Lead‑Based Paint Disclosure for homes built before 1978, and any known material defects documented on a Wisconsin Residential Property Condition Disclosure. Additional county‑specific forms may apply, so verify with your local Register of Deeds or a real‑estate attorney before signing anything.

Step‑by‑Step Checklist to Stay Compliant

  1. Identify the build year , Check the deed, tax records, or a recent appraisal.
  2. Download the SPDS , Fill every section honestly; “N/A” only if the question truly doesn’t apply.
  3. Run a lead‑paint test (if pre‑1978) , Use a certified lab; attach the EPA‑approved form.
  4. Gather repair records , Provide invoices, warranties, or contractor statements for any work done in the last 5 years.
  5. Ask the buyer for a property condition request , If they ask, supply the WAR disclosure.
  6. Check county requirements , Some counties demand a septic system report or a well water analysis. Call the Register of Deeds or visit the county website.
  7. Upload all PDFs to your listing , Whether you post on a FSBO site, a flat‑fee MLS, or Sellable, attach the documents so buyers can download them instantly.
  8. Sign and date each form , A notarized signature isn’t required, but it adds credibility and reduces disputes.
  9. Provide copies at closing , Your title company will need the signed disclosures to finalize the deed transfer.

Frequently Asked Questions

1. Do I need a Lead‑Based Paint Disclosure if my home was built in 1980?
No. The federal requirement applies only to homes constructed before 1978. You can skip the EPA form, but you may still provide it voluntarily if you suspect older paint.

2. What happens if I forget to disclose a known roof leak?
The buyer can demand a price reduction, terminate the contract, or sue for breach of contract. Providing the defect on the SPDS protects you from these outcomes.

3. Can I use a generic “as‑is” clause instead of the SPDS?
Wisconsin law still requires the SPDS. An “as‑is” clause does not replace the mandatory disclosure form.

4. Are there any extra disclosures for homes on a well or septic system?
Yes. Most counties require a recent well water test and a septic system inspection report. Verify the exact thresholds with your county health department.

5. How long must I keep the signed disclosure forms after the sale?
Wisconsin statutes advise retaining them for at least 3 years after closing in case a buyer raises a claim. Store digital copies in a secure folder or on Sellable’s document archive.
