The Home Sale Contingency: Buying and Selling at Once

TL;DR: A home sale contingency makes a buyer's purchase offer conditional on selling their existing home first, typically within a 30 to 90 day window written into the contract. Most sellers avoid these offers in competitive markets because they add risk and delay, but a kick-out clause can make them workable for both sides. If you're buying and selling at the same time, a bridge loan or a settlement contingency are usually stronger alternatives.

Selling your current home and buying the next one usually can't happen on the same afternoon, and that timing gap is where deals fall apart. A home sale contingency is the contract clause built to bridge that gap, but it comes with real tradeoffs for both the buyer making the offer and the seller deciding whether to accept it.

What is a home sale contingency and how does it work?

A home sale contingency is a clause that makes a buyer's purchase offer conditional on the sale of their current home closing by a specific date. If the buyer's house hasn't sold and closed by that deadline, usually 30 to 90 days from contract signing, the buyer can cancel the new purchase and get their earnest money back.

The clause exists because most buyers can't qualify for two mortgages at once, and many don't have enough cash sitting around to cover a down payment on a new place while still carrying their old one. Instead of asking a lender to stretch, the buyer asks the seller to wait. In practice, that means the seller's home comes off the active market (or stays marked "contingent") while the buyer's own listing plays out.

There are two flavors worth knowing apart. A "sale and settlement" contingency requires the buyer's home to already be under contract with another buyer when they make the offer. A "sale and closing" contingency is looser and lets a buyer submit an offer even before their own house is listed, which sellers view as riskier since there's no guarantee a buyer will even show up. Compare this to a financing contingency, which protects a buyer whose loan falls through rather than one whose sale falls through.

Why do sellers hesitate to accept a home sale contingency offer?

Sellers hesitate because the clause shifts timing risk onto them without much upside in return. Every day the property sits under a home sale contingency, it's effectively off the market for other buyers, and if the buyer's house doesn't sell in 60 or 90 days, the seller is back to square one, often after turning away other offers.

In a seller's market, this math gets worse for buyers. National Association of Realtors data has repeatedly shown that contingent offers lose out to non-contingent ones when inventory is tight, because sellers can simply wait for a cleaner offer with fewer moving parts. This is part of why contingent vs cash offers is such a common comparison. Cash and non-contingent offers close faster and carry less uncertainty, so sellers who have a choice usually take them even at a slightly lower price.

Sellers who do accept a home sale contingency typically protect themselves with a kick-out clause (sometimes called a right of first refusal). This lets the seller keep marketing the home, and if a second buyer makes a better offer, the original buyer usually gets 48 to 72 hours to remove their contingency and proceed, or step aside and get their deposit back.

How does a home sale contingency compare to other options for buyers?

It compares as the slowest but cheapest option among the common ways to buy before you sell. Buyers juggling both transactions generally choose between three paths: a home sale contingency, a bridge loan, or selling first and renting back temporarily.

| Option | Cost | Speed | Seller appeal | |---|---|---|---| | Home sale contingency | Low, just time | Slow, 30-90 days | Low, sellers often reject | | Bridge loan | High, interest plus fees | Fast, offer looks clean | High, no contingency needed | | Sell first, rent back | Moderate, rent + moving twice | Depends on rent-back terms | High, buyer looks like cash |

A bridge loan lets a buyer tap equity in their current home to fund the down payment on the next one, making their offer effectively non-contingent to the seller they're buying from. It costs more in interest and fees, often 1% to 2% of the loan amount plus a higher rate, but it removes the exact risk sellers dislike. Selling first and negotiating a short-term rent-back, sometimes 15 to 60 days, is another common workaround, especially for owners already thinking through selling with an existing mortgage and needing the payoff timed correctly.

How can buyers make a home sale contingency more attractive to a seller?

Buyers improve their odds by listing their current home before making an offer, pricing it to move, and building in a shorter contingency window than the market default. An offer with "sale and settlement" language, meaning the buyer's home is already under contract, is far more credible to a seller than one where the buyer hasn't even listed yet.

Some buyers strengthen the offer further by agreeing to a kick-out clause upfront rather than waiting for the seller to ask for one, and by offering a slightly higher price or a larger earnest money deposit to signal seriousness. In slower markets, this pairs well with the advice in when to sell in a slow market, since sellers with fewer competing offers are more willing to accept contingencies when they have less to lose by waiting.

If you're the seller weighing whether to accept, ask for proof the buyer's home is listed, check the days on market for comparable homes in their area, and get your agent's read on how quickly it's likely to sell. A 45-day contingency in a market where similar homes sell in 20 days is a very different risk than the same clause in a market averaging 90 days.

What happens if the buyer's home doesn't sell in time?

If the deadline passes without a closed sale, the contract typically terminates and the buyer's earnest money is returned, unless the buyer requests and the seller grants an extension. This is why the contingency deadline itself matters as much as the clause's existence. Vague or open-ended contingencies without a firm date are a red flag for sellers and usually get negotiated out before signing.

Some contracts include an automatic notice period, where the seller must give the buyer 72 hours' written notice before terminating, giving the buyer one last chance to waive the contingency and proceed without it if they've found other funds. Sellers should keep this notice requirement in writing and dated, since a missed notice can accidentally extend a contract far longer than intended.

FAQ

Is a home sale contingency the same as a financing contingency?

No. A financing contingency protects a buyer if their mortgage loan falls through, while a home sale contingency protects a buyer whose current home hasn't sold yet. A buyer can have both clauses in the same contract.

How long does a typical home sale contingency last?

Most range from 30 to 90 days, with 45 to 60 days being common in balanced markets. The exact number is negotiated and written directly into the purchase contract.

Can a seller back out if a better offer comes in?

Only if a kick-out clause is included. Without one, the seller is bound to the contingent buyer until the deadline passes, even if a stronger offer arrives in the meantime.

Do sellers ever prefer a home sale contingency over a cash offer?

Rarely, but it happens when the seller isn't in a hurry, when local inventory is thin, or when the contingent offer's price is meaningfully higher. In most markets, a clean or cash offer still wins on speed and certainty.

What's the difference between a sale contingency and a settlement contingency?

A sale contingency only requires the buyer's home to be listed, while a settlement contingency requires it to already be under contract with a buyer. Settlement contingencies are viewed as lower risk and are more often accepted.
