A home sale contingency is a clause in a real estate purchase contract that makes your obligation to buy conditional on selling your current home first. If your existing property doesn’t sell within an agreed window, usually 30 to 60 days, you can walk away from the new purchase and recover your earnest money deposit. Without that clause, a buyer whose home fails to sell can end up carrying two mortgages or forfeiting thousands of dollars in deposit money.
What the Addendum Actually Says
The contingency is written as a separate addendum attached to the purchase contract. It identifies your current property by full street address and legal description, including any parcel number or lot-and-block details from the deed. Vague property descriptions create enforcement problems if a dispute arises, so the specifics matter.
The addendum also locks in two dates. The first is the contingency deadline, meaning how long you have to get your current home under contract. The second is the closing deadline for that home. Both should be specific calendar dates rather than floating references like “within 45 days,” because ambiguous language invites arguments about when the clock started.
Sale Contingency vs. Settlement Contingency
These two terms sound interchangeable, but they cover different stages of the selling process and carry different risk profiles for the seller.
Sale Contingency
A sale contingency applies when you haven’t yet found a buyer for your current home. The new deal won’t move forward until you secure a signed contract from a third-party purchaser and that sale closes. This is the riskier version for the seller because two separate things still have to happen: your home has to attract an offer, and then that offer has to close. During the contingency window, the seller’s home sits in limbo.
Settlement Contingency
A settlement contingency is narrower. It applies when you already have a signed contract on your current home but haven’t reached the closing table. The marketing phase is done, and the only open question is whether the pending sale actually closes. It’s less risky for the seller because your transaction is further along, though deals can still collapse late from financing problems or a failed appraisal. If your sale doesn’t close by the date in the addendum, you can terminate the new purchase and recover your deposit.
The Kick-Out Clause
Sellers who accept a home sale contingency almost always insist on a kick-out clause. Without one, the property is effectively off the market while you try to sell your own home, with no guarantee the deal will close. The kick-out clause lets the seller keep marketing to other buyers during the contingency period.
Here’s how it plays out. If the seller receives another offer, they deliver written notice to you. That notice triggers a short response window, commonly 72 hours. You then face a straightforward choice: remove the home sale contingency and commit to buying without the safety net, or step aside and let the seller accept the new offer. A buyer who steps aside gets the earnest money back.
Removing the contingency under pressure isn’t a small decision. You’ll need to prove you can actually close without the sale proceeds, which means updated financial documentation showing enough liquid assets to cover the down payment, closing costs, and any reserves your lender requires.1Fannie Mae.

How the Contingency Affects Your Offer
In a competitive market, a home sale contingency makes your offer less attractive. The seller is betting that your home will sell and that the subsequent closing will go smoothly. That’s two layers of uncertainty compared to a buyer arriving with financing secured and no property to unload. Contingent offers also tend to stretch the timeline to 45 to 60 days or longer, while a buyer without one can often close in three to four weeks.
That doesn’t mean contingent offers never win. In a slower market with fewer competing bids, sellers are more willing to accept the added risk. You can strengthen a contingent offer by shortening the contingency period, increasing the earnest money to signal commitment, or pricing your existing home aggressively so it sells fast. Adding a kick-out clause from the start, rather than waiting for the seller to demand one, signals good faith and gives the seller a concrete escape route.
If your home is already listed and generating showings, say so in the offer. A contingent offer backed by evidence of active market interest reads very differently from one where the buyer hasn’t even called a listing agent yet.
Satisfying or Waiving the Contingency
Satisfying It
Once the contingency is active, list your property promptly. Sitting on the listing for weeks before going to market undermines your position and gives the seller grounds to question whether the deadline will be met.
When you receive an acceptable offer on your current home, deliver a copy of the signed purchase agreement to the seller, typically within 24 to 48 hours. Then submit a written contingency removal form confirming you’re moving forward to closing. At that point the contingency is satisfied, and the purchase contract becomes unconditional.
Waiving It
You can also decide to proceed without selling first. Waiving involves signing a written waiver and providing the seller with proof you can close without the sale proceeds. Your documentation needs to show enough liquid assets or lending capacity to cover both transactions.
Waiving is irreversible. Once the form is signed, you’ve given up your right to exit based on your home not selling. If you then can’t close, you’re in breach.
What Happens If You Default
Buyers sometimes underestimate what’s at stake after waiving a contingency or letting a deadline pass. The most immediate consequence is losing the earnest money deposit, which typically runs 1% to 3% of the purchase price. On a $400,000 home, that’s $4,000 to $12,000 gone.
The deposit isn’t necessarily the ceiling. Many purchase contracts include an election clause giving the seller a choice: keep the earnest money as liquidated damages, or sue for actual damages instead. Actual damages can include the difference between the contract price and what the seller eventually gets from another buyer, carrying costs while the home sat back on the market, and legal fees. Courts are split on whether these election clauses hold up. Some rule that the option to pursue actual damages undermines the whole concept of liquidated damages, limiting the seller to the lesser of the deposit or actual damages. Others enforce the clause as written, leaving the buyer exposed well beyond the deposit.
The most aggressive remedy is specific performance, where a court orders you to actually complete the purchase. This exists because courts treat every piece of real property as unique, meaning money alone can’t fully compensate a seller who loses the deal. A specific performance lawsuit can also cloud the title, effectively preventing the seller from selling to anyone else while the case is pending. That leverage often forces settlements even when the underlying claim is weak.
Alternatives If You’d Rather Skip the Contingency
If you want to avoid the competitive disadvantage of a home sale contingency, you’ll need another way to bridge the financial gap between buying and selling.
Bridge Loans
A bridge loan is a short-term loan that uses your current home’s equity to fund the down payment on your new home. These loans are structured as interest-only payments with terms of six to twelve months, giving you time to sell and pay off the bridge loan from the proceeds. The trade-off is cost. Bridge loan interest rates run significantly higher than conventional mortgage rates, and lenders charge origination fees on top. This route works best when you’re confident your current home will sell within a few months, because every month of interest adds to your total transaction cost.
Home Equity Line of Credit
If you have substantial equity in your current home, a HELOC lets you borrow against it for the down payment on your next property. The advantage over a bridge loan is that you may already have the HELOC in place, avoiding a new loan application. The drawback is that the HELOC payment counts in your debt-to-income ratio when you apply for the new mortgage, which can push you past lender thresholds.
How Lenders View Two Mortgages
Carrying two mortgage payments at once tightens your borrowing capacity. For a qualified mortgage, the maximum back-end debt-to-income ratio is 43%, meaning all monthly debt obligations including both mortgages can’t exceed 43% of gross monthly income.2Consumer Financial Protection Bureau. Qualified Mortgage Definition Under the Truth in Lending Act Some loan programs allow higher ratios with compensating factors like large cash reserves, but the standard threshold is where most buyers hit a wall.
Lenders also require liquid reserves after closing, and those requirements grow with the number of financed properties you own. One helpful exception: if your current home is already under contract, its mortgage balance is excluded from the calculation.3Fannie Mae. Minimum Reserve Requirements That’s another reason a settlement contingency is viewed more favorably than a sale contingency.
A Timing Note on Capital Gains
If your current home has appreciated significantly, the timing of the sale can affect your tax bill. Federal tax law lets you exclude up to $250,000 in capital gains from the sale of your primary residence, or $500,000 if you’re married filing jointly. To qualify, you need to have owned and lived in the home for at least two of the five years before the sale.4Internal Revenue Service. Publication 523, Selling Your Home
This matters for contingency planning because buyers who move into a new home before selling the old one start the clock on a potential problem. If you’ve already relocated and the sale drags out beyond the five-year window, you could lose eligibility for the full exclusion. For most homeowners who’ve lived in the home for years, this won’t be an issue. But if you bought relatively recently or if your timeline stretches because the market softens, track the dates. Gains above the exclusion threshold are taxed at the long-term capital gains rate, which is 15% for most filers and 20% at higher income levels.4Internal Revenue Service.
