Key takeaways
  • A seller must disclose latent defects, meaning defects that make a property unfit for habitation, dangerous or potentially dangerous.
  • A seller does not have to disclose patent (visible) defects but must not conceal them.
  • Buyer beware expects you to do your own inspections and due diligence before waiving conditions.
  • A Seller Property Information Statement reflects only the seller's personal knowledge.

Many buyers find a problem after closing: a leak behind a wall, a failing foundation, a history nobody mentioned. Many sellers worry that an honest answer will cost them a sale or that silence will cost them later. Both want to know where the line is.

This article explains the key ideas: latent and patent defects, the Seller Property Information Statement, and the principle of buyer beware. It also covers what happens to the deposit if a deal falls apart. It is general information, and a real estate lawyer can apply it to your facts.

Latent and patent defects

The rules turn on whether a defect is hidden or visible. RECO states that a seller must disclose latent defects, meaning defects that make a property unfit for habitation, dangerous or potentially dangerous. A seller does not have to disclose patent (visible) defects, but must not conceal them.

RECO also notes that the duty to disclose a latent defect comes from case law, not TRESA. In practice this means the answer in a given case depends on its facts, and it is worth getting legal advice when a serious problem is involved.

What buyer beware really means

Under buyer beware, the buyer is expected to do their own inspections and due diligence before waiving conditions. That is why home inspections, status checks and questions to the seller matter. The principle is not a free pass for sellers, though. RECO notes that concealing a patent defect may mean the principle does not apply.

The Seller Property Information Statement

A Seller Property Information Statement is a form in which the seller records what they know about the property. It can be completed for buyers or only for the seller's agent. If it is meant to inform buyers, the agent must tell every interested buyer it exists and give a copy on request.

It reflects only the seller's personal knowledge. A seller who answers carefully and honestly is better protected than one who guesses or leaves out something they know. A buyer should treat the statement as a starting point, not a substitute for an inspection.

When a seller can be liable for hidden problems

A seller can be liable for a latent defect without direct knowledge if the seller was willfully blind about it. Willful blindness is deliberately avoiding finding out something you suspect. A seller cannot avoid the duty by refusing to look into a problem they have reason to suspect.

Whether a particular seller is liable depends on what the defect is, what the seller knew or suspected, what they said and what the buyer could have found out. Buyers who find a problem after closing should keep records and photos, avoid repairs that destroy the evidence, and speak to a lawyer promptly. Time limits can apply to legal claims, and a lawyer can confirm them.

If the deal falls through: the deposit

Disclosure disputes sometimes end a deal before closing, and then the deposit becomes the issue. A brokerage must deposit a deposit it is to hold into its real estate trust account within five business days, and may pay it out only in accordance with the terms of the trust. If the buyer and seller dispute who gets it, the brokerage can release it only under a mutual release signed by both, or under a court order.

RECO consumer deposit insurance responds to brokerage theft, fraud, insolvency or misappropriation of funds, and does not resolve a disagreement between buyer and seller about entitlement. Money held two years with entitlement unclear must be paid to RECO.

What to do next

The steps differ slightly for buyers and sellers, but both should act before anything is signed.

Frequently asked questions

Does a seller have to tell me about every problem with the house?

No. A seller must disclose latent defects, which are defects that make the property unfit for habitation, dangerous or potentially dangerous. A seller does not have to disclose patent (visible) defects, but must not conceal them.

Is the Seller Property Information Statement required?

It can be completed for buyers or only for the seller's agent. If it is meant to inform buyers, the agent must tell every interested buyer it exists and give a copy on request. Ask your agent how it applies to your sale.

Can a seller be responsible if they did not know about a defect?

Possibly. A seller can be liable for a latent defect without direct knowledge if the seller was willfully blind about it. Whether that applies depends on the facts, so a lawyer should look at the details.

Who gets the deposit if the sale collapses?

If the buyer and seller disagree, the brokerage can release the deposit only under a mutual release signed by both, or under a court order. Consumer deposit insurance does not resolve that kind of disagreement.
