Quick Answer
If you need the proceeds or equity from your current house to buy the next one, a home sale contingency ties the two transactions together, protecting you from being on the hook for two mortgages, or none at all if your sale falls through. Sellers weigh these carefully since they add uncertainty and often a longer timeline to the deal.

Why Sellers Are Cautious
A home sale contingency introduces a chain: if the buyer's own home doesn't sell in time, the deal you're counting on can collapse too. Many sellers, especially in a competitive market, prefer offers without one.
To manage that risk, sellers often negotiate a kick-out clause, which lets them keep marketing the home and accept a better offer if one comes along, giving the contingent buyer a set window to remove their contingency or step aside.
When It Makes Sense Anyway
For buyers who can't qualify for two mortgages at once or don't want to carry both, a home sale contingency can be the only realistic path forward, especially when paired with a strong, already-listed home.
Your agent can help you weigh this against alternatives, like a HELOC or bridge financing, or simply listing and selling first before writing an offer.

Frequently Asked Questions — Home sale contingency
What is a kick-out clause?
It lets the seller keep the home on the market and accept a better offer, giving the contingent buyer a limited time to remove their contingency or lose the deal.
Are home sale contingencies common in a hot market?
They're harder to get accepted when sellers have multiple offers, since many prefer certainty over a linked sale.
Is there an alternative to a home sale contingency?
Some buyers sell first and rent back temporarily, or use short-term financing, to make a stronger, non-contingent offer.
Does my current home need to be under contract already?
Requirements vary by offer; some sellers accept a contingency once your home is listed, others require it already under contract.
