A signed real estate purchase agreement is typically good for 30 to 60 days for a standard residential sale, with the exact length set by the closing date and the contingency deadlines written into the contract. Cash deals can wrap in as little as two weeks. Commercial transactions and new construction routinely run 90 days or longer. There is no single expiration clock on the document itself; several overlapping deadlines govern financing, inspection, appraisal, and closing, and the agreement stays alive until one of them ends it.
Typical Length by Transaction Type
How long your agreement stays in effect depends mostly on how the buyer is paying and what kind of property is changing hands.
- Conventional mortgage purchases average about 42 days to close, which is why 30- to 60-day agreements are standard for residential deals.
- Government-backed loans like FHA and VA add steps such as government appraisals and often push closing past 60 days, sometimes beyond 70.
- Cash purchases can close in roughly two weeks, so the agreement period is correspondingly short.
- Commercial properties involve due diligence, environmental review, and zoning checks that commonly stretch agreements to 90 days or more.
- New construction can run well past 90 days, since the closing date is often tied to building milestones rather than a fixed calendar date.
Some jurisdictions also give either party’s attorney three to five business days after signing to cancel or modify the contract, which adds a brief review window at the front end before the real timeline begins.
The Deadlines That Actually Control the Clock
The headline length of an agreement is less important than the individual deadlines inside it. Each contingency has its own due date, and any one of them can end the contract early.
Inspection Contingency
The buyer usually has 7 to 10 days from signing to inspect the property. If the inspection finds serious problems, the buyer can negotiate repairs, ask for a price cut, or walk away. Once the deadline passes without objection, the contingency is typically waived and the agreement continues toward closing on the remaining terms.
Financing Contingency
This window generally runs 30 to 60 days, matching the time a lender needs to underwrite and approve the loan. A buyer whose mortgage application is denied within that period can cancel and recover the earnest money. A buyer who waived this contingency to win a competitive bid stays on the hook even if the loan falls through.
Appraisal Contingency
If the lender’s appraisal comes in below the purchase price, the buyer can ask the seller to lower the price, cover the gap in cash, split the difference, or exit the contract. Without this contingency, a low appraisal doesn’t give the buyer a clean way out.
Miss a contingency deadline without an extension and the protection it offered is gone. That doesn’t automatically kill the agreement, but it does narrow the buyer’s options for the rest of the transaction.
The Closing Date and Time Is of the Essence
The closing date is the agreement’s primary finish line, the day ownership transfers and funds move. How strict that date is depends on the contract’s language.
In most residential contracts, the closing date functions as a target rather than a hard cutoff. Courts in many jurisdictions treat a missed closing date as a minor issue when both parties are still working in good faith, and reasonable delays for loan processing or title problems usually won’t end the deal by themselves.
A “time is of the essence” clause changes that. With that language in the contract, every deadline becomes legally strict, and missing the closing date is a material breach. The non-breaching party can terminate the agreement, and the buyer risks losing the earnest money deposit. Some agreements contain the clause from the start. In other cases, one party sends a formal notice making time of the essence after delays have already piled up, converting flexible dates into firm ones with a new deadline attached.
If the closing date passes without a completed transaction and without an extension, the agreement simply lapses.
Extending the Agreement
When a deadline is approaching and the deal isn’t ready, the fix is a written addendum. The addendum should state the original agreement date, the deadline being changed, and the new deadline. Common uses are pushing out the closing date or extending a contingency.
Both parties have to sign. Neither side can push a deadline back on their own. If the seller refuses to extend, the buyer has to close on time, let the agreement expire, or risk being in breach. Sellers sometimes decline when they believe the property would fetch more on a relist, so an extension is never automatic.
Verbal agreements to extend don’t hold up. Real estate contracts have to be in writing under the Statute of Frauds, and that applies to changes as well as to the original deal.
What Ending the Agreement Means for Your Deposit
Earnest money, usually 1% to 3% of the purchase price, is the buyer’s financial stake, and what happens to it depends on why and when the agreement ends.
If the buyer cancels within a valid contingency period, the deposit comes back. Financing fell through before the financing deadline, the inspection revealed defects the seller won’t fix, or the appraisal came in low and the seller won’t adjust. Each of those scenarios protects the buyer.
The deposit is at risk when a buyer backs out for reasons the contract doesn’t cover, or after the relevant contingency deadlines have passed. Missing a key deadline without an extension, changing your mind, or finding a different property can all mean forfeiture, with the seller keeping the money as compensation for taking the property off the market. Waiving a contingency sharpens that risk, since the deposit effectively becomes non-refundable for whatever was waived.
How a Purchase Agreement Can End Before Closing
Several things can shut down an agreement before its closing date:
- Contingency failure, the cleanest exit, where a failed inspection, denied mortgage, or low appraisal within the contingency window gives the buyer a way out.
- Breach of contract, where one party fails to meet their obligations or misses a “time is of the essence” deadline.
- Mutual termination, where both parties sign a written cancellation and sometimes negotiate how the earnest money is divided.
- Expiration, where the closing date passes without completion or an extension and the agreement lapses on its own.
One thing that won’t end your agreement: a federal three-day right to cancel. Buyers sometimes assume the FTC’s Cooling-Off Rule gives them a window to back out of any major purchase, but real estate transactions are specifically excluded.1Federal Trade Commission. Buyers Remorse: The FTCs Cooling-Off Rule May Help Your ability to cancel comes from the contingencies you negotiated into the contract, not from a blanket federal protection. Read the deadlines in your agreement, mark each one on a calendar, and treat them as the real answer to how long your contract is good for.
