You buy a house. Six months later, the basement floods. You find out the previous owner had filed three insurance claims for water damage. The seller never told you. Your real estate agent never asked. Now you are stuck with a soggy basement, thousands in repair bills, and a major drop in your home’s value. Who pays for this mess? In many cases, the real estate agent does.
Real estate agents are professionals. They hold licenses. They take classes. They pass exams. When they mess up, they get sued under professional liability. This is not the same as a doctor making a surgical error or a lawyer missing a court deadline. It falls under the same general idea though. A professional promises you a certain standard of skill and knowledge. If they fall short and you get hurt, they owe you compensation.
The most common professional liability claim against real estate agents involves failure to disclose defects. Every state has laws requiring sellers and their agents to tell buyers about known problems with a property. These problems can be structural, like a cracked foundation. They can be mechanical, like a broken furnace. They can be environmental, like mold or radon. They can even be legal, like an unpermitted addition that the city could force you to tear down. The key word here is known. The agent does not have to be psychic. They cannot be held liable for a defect they had no way of knowing about. But if the agent knew or should have known about a problem, and they kept quiet, that is a professional liability claim waiting to happen.
What does should have known mean in plain English? It means the agent did not do their homework. A good agent does not just take the seller’s word that everything is fine. They walk the property. They look in the attic. They check the crawlspace. They ask neighbors about flooding. They review permits at the city building department. They notice mismatched paint on a ceiling that suggests a past leak. An agent who skips these steps is not meeting the standard of care for their profession. If a buyer later discovers a defect that a minimally competent agent would have caught, the agent can be on the hook.
The buyer must also show that the defect caused actual harm. It is not enough to prove the agent was lazy or sloppy. The buyer must prove they lost money because of it. That harm usually comes in two forms. First, the cost to fix the problem. Second, the loss of value the property suffers even after repairs. If a buyer paid full price for a house with a hidden termite infestation, the compensation is the cost of extermination and any necessary structural repairs, plus the reduction in the home’s resale value because of the damage history.
Insurance matters here. Most real estate agents carry professional liability insurance, usually called errors and omissions insurance. This policy pays for legal defense and settlements when a client sues the agent for a mistake. But insurance is not automatic. If the agent intentionally hid a defect, the policy will likely deny coverage. Insurance covers negligence, not fraud. An agent who knew about a leaky roof and lied about it is committing fraud. The insurance company will walk away, and the agent pays out of their own pocket.
There is also the question of who the agent works for. In most home sales, the agent legally represents the seller. Their duty is to the seller, not the buyer. This can confuse people. The buyer might think the agent showing them houses is on their side. Legally, that agent owes loyalty to the seller. But even a seller’s agent has limits. They cannot lie to the buyer. They cannot hide a material fact, meaning a fact that would affect the buyer’s decision to buy or the price they are willing to pay. An agent who stays silent about a known defect violates their duty to the buyer, even if the buyer is not technically their client.
The practical takeaway for buyers is simple. Do not assume the agent will tell you everything. Ask direct questions. Put requests in writing. Hire your own inspector. Check public records yourself. If you find a defect after closing that the agent knew about or should have known about, document everything. Get repair estimates. Track your out-of-pocket costs. Then talk to a lawyer who handles professional liability claims. The statute of limitations, or the deadline to file a lawsuit, varies by state, but it often runs two to four years from the date you discovered the problem. Waiting too long can kill your claim.
For agents, the lesson is equally clear. Disclose everything you know. When in doubt, disclose anyway. Do not let a seller talk you into keeping quiet for the sake of a quick sale. Your license, your reputation, and your personal finances are on the line. One undisclosed defect can end a career.
