Warranties in a real estate contract are the seller’s legally enforceable promises that specific facts about the property — its title, its condition, its history — are true. Some you negotiate into the contract yourself. Others the law gives you automatically. A few are written into the deed and survive long after the deal closes. Knowing which is which, and what you have to do to keep them alive past the closing table, is the difference between a real remedy and an expensive surprise.
Express Warranties You Negotiate Into the Contract
Express warranties are specific promises the seller writes into the purchase agreement. The roof is less than five years old. The HVAC runs. No addition was built without a permit. The basement has never flooded. Each is a statement of fact the seller is willing to stand behind in writing.
You don’t need the words “warrant” or “guarantee” for a statement to count. Any factual claim about the property that becomes part of the deal can function as an express warranty, as long as it’s more than vague sales talk. “The basement has never flooded” is a warranty. “This house is a gem” is not.
Verbal promises almost never survive. Because real estate contracts fall under the statute of frauds, a seller’s spoken assurance that the plumbing was replaced last year is nearly impossible to enforce if the contract itself says nothing about it. If a promise matters to you, it belongs on the page.
Implied Warranties the Law Gives You Automatically
Implied warranties arise by operation of law. Neither party has to mention them for them to apply. Two matter in residential sales.
Habitability and Workmanship on New Construction
When you buy a newly built home from a builder, courts in most states recognize an implied warranty of habitability: by selling you the home, the builder is promising it was competently built and fit to live in. The warranty reaches defects a reasonable inspection wouldn’t catch at purchase, like foundation problems that only emerge after a season of settling or plumbing defects hidden behind walls.1Legal Information Institute. Implied Warranty
A closely related implied warranty of good workmanship asks whether the work was done to the standard a competent builder would meet. Both apply to builder-vendors, not individual homeowners reselling an existing house. Subsequent buyers can often enforce these warranties against the original builder even without a direct contract with them, so a latent construction defect that appears a few years in may still be the builder’s problem. How long the warranties last varies by state.
Marketable Title on Every Sale
The implied warranty of marketable title applies to essentially every real estate sale. When a seller agrees to sell, the law presumes a promise that the title is clean enough to transfer without exposing you to lawsuits or ownership disputes.2Legal Information Institute. Marketable Title
A marketable title is free from liens, competing ownership claims, adverse possession risks, and zoning violations that would make a reasonable buyer hesitate. If the seller can’t deliver one at closing, you can typically walk away or demand that the defect be cleared first.2Legal Information Institute. Marketable Title
Title Warranties Written Into the Deed
The deed you receive at closing carries its own set of title warranties, separate from anything the contract says. There are three common forms, and the differences are not academic.
- General warranty deed. The strongest protection. The seller guarantees clear title not just during their own ownership but across the entire chain of title. A problem traced to a transfer 30 years ago is still the seller’s responsibility.
- Special warranty deed. Covers only the period the seller owned the property. A claim based on something that happened before they took title is yours to deal with.
- Quitclaim deed. Transfers whatever interest the seller has, with no warranties at all. The seller doesn’t even promise they own anything. Common between family members or divorcing spouses, not in arm’s-length sales.
In a standard purchase, ask for a general warranty deed. A seller offering only a quitclaim in a regular transaction is worth asking hard questions about before you go further.
Why Contract Warranties Often Die at Closing
This is where buyers get hurt most often. Under the merger doctrine, when you accept the deed at closing, the terms of the purchase contract are considered merged into the deed and extinguished. The contract, as an independent document, is gone.3Legal Information Institute. Merger
That express warranty you negotiated about the foundation? Unless the contract said otherwise, it died the moment you accepted the deed. What survives is whatever the deed itself warrants, which covers title, not condition.
The fix is a survival clause. It states, in plain language, that specified warranties continue for a defined period after closing. Residential survival periods commonly run from six months to two years, but the parties can agree to whatever makes sense. Without one, a defect you discover a month after closing may leave you with no contractual remedy at all. Raise this with your attorney before you sign the purchase agreement, not after.
What “As-Is” Clauses Can and Cannot Do
The seller’s main tool for limiting exposure is the “as-is” clause. It signals that no guarantees are being made about the property’s condition and that you’re accepting whatever you find.
An as-is clause is not a universal shield. To hold up, warranty disclaimers generally need to be written clearly, placed conspicuously, and specifically understood by the buyer.1Legal Information Institute. Implied Warranty And it does not protect a seller who actively conceals a known defect or commits fraud. A seller who knew the basement flooded every spring and said nothing can’t hide behind “as-is.”
On new construction, disclaiming implied warranties is harder still. Many states require specific language identifying which implied warranties are being waived, and some don’t allow the implied warranty of habitability to be disclaimed at all. Generic boilerplate won’t do the work.
One Disclosure You Cannot Disclaim
Federal law overrides contract language on lead-based paint. For homes built before 1978, sellers and their agents must disclose any known lead paint hazards, provide available testing records, and give you a 10-day window to conduct your own lead paint inspection before the contract becomes binding. No as-is clause removes this obligation. Civil penalties for violations can reach tens of thousands of dollars per occurrence, and sellers must keep signed disclosure documents for at least three years after the sale.4US EPA.

What You Can Collect When a Warranty Is Broken
If a warranty turns out to be false, your options depend on how serious the breach is and what the contract allows.
- Monetary damages. The usual remedy. You recover what it costs to fix the problem, or the gap between what the property was worth as warranted and what it’s actually worth. A warranted new roof that needs $15,000 in repairs is a straightforward damages claim.
- Rescission. For breaches serious enough to undermine the whole deal, a court may cancel the contract and try to return both sides to where they started. A warranted clean title with a massive undisclosed lien is the classic case.
- Specific performance. A court order making the seller actually do what was promised. More common with title defects the seller can still cure than with condition issues.5Legal Information Institute. Breach of Warranty
Many contracts also require written notice to the seller within a set window before you can file suit. If yours does, follow it exactly. Skipping the notice step can forfeit the claim even when the breach itself is obvious.
Home Warranty Plans Are Not the Same Thing
One last distinction worth drawing clearly. A home warranty plan is a service contract from a third-party warranty company, usually covering appliances and major systems like HVAC, plumbing, and electrical for a year after closing. Annual premiums run from a few hundred to over a thousand dollars.
These plans have real limits. Pre-existing conditions, improper installation, deferred maintenance, and code violations are routinely excluded. Roofs, foundations, structural components, and exterior elements are almost never covered. Each covered item carries a payout cap, and anything above it comes out of your pocket.
A seller’s contractual warranty is different in kind. It’s a personal promise backed by legal liability, with remedies set by contract law. A home warranty plan is a bet on future breakdowns with a company that writes its own fine print. Both can be useful. Neither replaces the other, and no home warranty plan substitutes for strong warranties in the purchase contract and careful due diligence before you close.
