What Is a Home-Sale Contingency? When You Must Sell to Buy

A home-sale contingency makes your offer to buy a new home conditional on selling your current one: if your existing home doesn’t sell (or doesn’t close) within the agreed window, you can walk away from the purchase and, in the standard setup, keep your earnest money. It’s the contract clause for the most common predicament in residential real estate — most move-up buyers need the equity from house one to afford house two.

Simple in concept. In practice, it’s one of the weakest cards you can put in an offer, and understanding why is the difference between using it well and losing the house you wanted.

What it actually covers

The details live in the addendum, not in folklore, but a Washington home-sale contingency typically specifies:

• The deadline — a date or window by which your current home must go under contract, or actually close, depending on how the form is written. “Under contract” and “closed” are very different promises; know which one you signed.
• What happens if you miss it — usually the right to terminate and recover earnest money, sometimes after a notice-and-response exchange.
• The seller’s escape hatch — almost always a kick-out clause, letting the seller keep marketing the home and “bump” you if a better offer arrives. If you receive a bump notice, you must waive the contingency within a short window or be released. The two clauses travel together; read them as one mechanism.

If your current home is already under contract, you may instead use a narrower pending-sale version — contingent only on that existing transaction closing. Sellers treat that far more kindly, because the hard part (finding your buyer) is already done.

Why sellers resist it

Put yourself in the seller’s chair: you’re being asked to take your home off the full market based on an event nobody controls — the sale of a property the seller has never seen, at a price you hope is right, to a buyer who doesn’t exist yet. In a competitive Seattle offer review, a home-sale-contingent offer usually loses to a clean one even at a lower price, because certainty is worth real money. Where these offers succeed is on listings with less competition — homes that have sat, niche properties, slower seasons — or when paired with a price or terms sweet enough to compensate for the wait.

The alternatives, honestly compared

Before you write a contingent offer, price out the other routes:

• Sell first, then buy — strongest position, but you may need interim housing; a rent-back from your buyer can bridge the gap.
• Bridge loan or HELOC — borrow against the old house to close the new one, then repay when it sells. Costs real money; buys real negotiating strength. See bridge loans in Seattle.
• Buy contingent — cheapest on paper, weakest in a bidding war, and you live under the kick-out clock.

The full decision tree is in buying and selling at the same time in Seattle.

The mistakes that hurt

The expensive ones are predictable: overpricing your current home while the contingency clock runs (the deadline doesn’t care about your list price); receiving a bump notice with no financing plan B, forcing a panicked waiver or a forced exit; and treating the contingency as a free option — sellers read it as risk, and you pay for it somewhere, usually in price or in losing the house to a cleaner offer.

Selling one home and buying another also means paying agent fees twice — worth knowing the going rates.
