Seller Disclosure and What You Must Tell a Buyer

You know the basement took on water in 2021, and you fixed it. Now the listing goes live next week and you are staring at a seller disclosure form, wondering whether a repaired problem still counts and what happens if you leave it off. That question decides whether your sale closes cleanly or ends up in a demand letter eight months later.

I have watched sellers lose more money to a vague answer on this form than to any price reduction. Here is how the seller disclosure works, what belongs on it, and how to fill it in so it protects you instead of exposing you.

What a seller disclosure is and why it exists

A seller disclosure is a written statement, usually on a state or association form, where you describe the known condition of the property. Most US states require one for residential resales, and the forms typically run four to ten pages of yes, no and unknown questions covering the roof, foundation, plumbing, electrical, water intrusion, pests, environmental hazards, permits and legal issues such as boundary disputes.

The key word is known. You are not expected to inspect your own home like a professional. You are expected to tell the buyer what you actually know, or reasonably should know, about material defects. A material defect is anything that would significantly affect the value of the home or a reasonable buyer's decision to buy it.

A handful of states lean toward buyer beware and require little or no formal disclosure. Even there, actively hiding a defect, such as painting over a fresh water stain before showings, can still be treated as fraud. The form changes; the duty not to conceal does not.

What to put on the seller disclosure form

Work through the house system by system with your records in front of you. Receipts, warranties, inspection reports from when you bought, insurance claims and permit paperwork all jog your memory and give you dates.

• Water. Any leak, flood, sump pump failure or damp crawl space, even if repaired. Give the year and the fix.
• Roof. Age if you know it, past leaks, and any repairs or insurance claims.
• Structure. Foundation cracks, settling, sticking doors that started suddenly, any engineer's report.
• Systems. Age of the furnace, air conditioning and water heater, and known problems with wiring or plumbing, including old materials like polybutylene pipe.
• Work without permits. A finished basement, added bathroom or garage conversion done without permits must be disclosed where the form asks. Buyers and appraisers check county records.
• Environmental items. Lead paint for homes built before 1978 requires a separate federal disclosure. Radon test results, mold and underground oil tanks belong here too.
• Legal and neighbourhood. HOA disputes, pending assessments, easements, encroachments and, in some states, deaths on the property.

How to word a repaired problem

Disclose it, then show the repair. "Water entered the northeast basement corner during heavy rain in April 2021. French drain and sump pump installed by a licensed contractor in June 2021, invoice attached. No water since." That sentence costs you nothing in most negotiations. Leaving it off, and having a neighbour mention it to the buyer at the barbecue, costs you a great deal.

Why "disclose everything" is the wrong instinct

The common advice from nervous agents is to disclose everything you can think of. It sounds safe, but it often backfires. A form stuffed with speculation, such as "we think the previous owner might have had termites" or "the electrician once said the panel was older", reads to a buyer like a house full of trouble. It can also create claims you never needed to make.

The better rule is to disclose every fact you know, precisely, and never guess. If you do not know whether the attic insulation contains vermiculite, answer unknown rather than inventing a story in either direction. If a contractor told you something specific, write what they said and when. Short, factual and dated beats long and anxious.

The one area where over disclosing is genuinely safer is anything involving water or structure. Those are the two defects behind most post closing claims, and buyers' attorneys know it.

Timing, costs and what happens after you sign

Most states require the disclosure before the buyer signs a purchase contract or within a few days after. In California, for example, buyers can cancel within three days of receiving the statement in person, or five days if it was mailed. Check your own state's deadline with your agent, because a late form can hand the buyer an easy exit.

Some sellers order a pre-listing inspection, usually 350 to 600 dollars for an average single family home. It gives you a list of issues before buyers find them, so you can fix the cheap ones and price in the expensive ones. Be aware that once you have the report, everything in it becomes known to you and generally must be disclosed. Many sellers decide that is a fair trade, because a surprise found during the buyer's inspection tends to cost far more than the repair. A realistic list price set with full knowledge of condition also holds up better, as explained in pricing a home right the first time.

If something new happens after you sign, such as a burst pipe a week before closing, you usually must update the disclosure. Tell your agent the same day.

Selling as is does not cancel your disclosure duty

Sellers often assume an as is listing lets them skip the paperwork. In most states it does not. As is means you will not make repairs; it does not mean you can stay silent about defects you know of. Buyers still expect full disclosure, and the guide to selling a house as is covers what else they will look for.

The same applies to estate sales and inherited homes. Executors who never lived in the property can often answer unknown more freely, and some states exempt estate sales from the standard form, but anything the executor actually learns, such as a contractor's estimate found in the files, should still be shared.

What happens if you leave something off

If a buyer discovers a known defect you did not disclose, they may sue for repair costs, loss of value or, in serious cases, to cancel the sale. Claims typically rest on misrepresentation, fraud or breach of the state disclosure statute. Legal fees alone can run into five figures before anyone gets near a courtroom.

Honest mistakes are treated differently from concealment, which is another reason to answer unknown when you truly do not know. Keep a copy of the signed form, your repair receipts and any reports for at least several years after closing.

Frequently asked questions

Do I have to disclose problems that were fixed?

In most states, yes, if the form asks about past issues, and many forms do. Disclosing a past problem along with the repair details, dates and invoices is usually reassuring to buyers. It also removes the risk of a later claim that you hid it.

Can a buyer back out after reading the seller disclosure?

Often, yes. Many states give buyers a short window, commonly three to five days, to cancel after receiving the disclosure. Contract contingencies for inspection can give them further room to renegotiate or walk away.

Who fills out the seller disclosure, the seller or the agent?

The seller does, because it covers the seller's own knowledge. Your agent can supply the correct form and explain the questions, but they should not answer for you. Agents usually have their own separate duty to disclose defects they notice.
