Two situations, same clause, and both of them make people nervous.
You found the home you want, but your current house has not sold. Or you are the seller, and the good offer on your table depends on a house you have never seen selling first.
This is the sale of property condition, and I have had it work beautifully and I have had it fall apart. The difference is almost never luck. It is the homework done before anyone signs.
The direct answer
A sale of property condition means the purchase only completes if the buyer sells their existing home within an agreed timeframe. It lets a buyer commit without the risk of carrying two properties. For the seller, it means accepting an offer whose success depends on a second transaction they do not control.
It is not a bad clause. It is a clause that needs to be examined properly, and that examination looks different depending on which side of the table you are on.
If you are the buyer
Wanting this condition is completely reasonable. Very few people can comfortably carry two mortgages, and buying unconditionally before selling is a genuine financial risk. There is no shame in needing the protection.
But understand what you are asking the seller to do, because that shapes how you should approach it.
- How fast can you actually get to market? If your home needs two weeks of preparation before photos, say so honestly and build it into the timeline. A condition period that expires before your home is even listed helps nobody.
- What is the seller's motivation? A seller who needs to close quickly is far less likely to accept. One with a flexible timeline may be genuinely open to it.
- How long has their home been on the market? This one matters more than most buyers realize. A listing that has sat for a while makes a seller much more receptive to a conditional offer than a fresh listing with showings booked all weekend.
- What are you giving up elsewhere? Because you are asking for flexibility, expect the price and other terms to reflect that. A conditional offer usually needs to be stronger somewhere else to compete.
This is precisely where having a strategic agent on your side earns their keep. The clause is negotiable in a dozen small ways, and how it is written determines whether it protects you or just delays your disappointment.
If you are the seller receiving one of these
Here is the honest problem. You are being asked to commit to a buyer based on a property you know almost nothing about.
To be clear, you are usually not taking your home off the market. In practically every one of these deals I have seen, the offer includes an escape clause, so your home stays listed, showings continue, and you can still entertain other offers. That protection is almost always there. But you have still accepted a conditional deal, you have signalled a price and terms, and you are further along with this buyer than with anyone else. That commitment is real even with the escape clause in place.
And you are making it half-blind. You have the buyer's address on the offer. You can look at the outside on Google Maps. That is roughly it. You have no idea what it looks like inside. It could be immaculate. It could need thirty thousand dollars of work before anyone will touch it.
So these are the questions I ask, every time, before advising a client to accept:
- Is their home already listed? If yes, that is a genuinely good sign. It means they are serious, it is on the market, and you can see it. A previous listing that expired also tells you something useful.
- What price will they list at? This is the big one. A realistic price means a realistic chance. An optimistic price means you are tying up your home while they test a number the market will reject.
- How is that specific neighbourhood performing? Their asking price only matters in the context of what is actually selling around them. A fair price in a slow pocket is still a slow sale.
- Will they reduce the price if there is no offer in the first week or two? Ask directly. A buyer genuinely committed to selling will say yes. Hesitation here is your answer.
And make sure there is an escape clause, which in my experience almost every one of these offers already includes. It lets you keep marketing your home the entire time. If a better offer arrives, the first buyer gets a short window, often 48 or 72 hours, to firm up or release. It is the single thing that turns this from a risky pause into a manageable one, so confirm it is there and that you understand exactly how it works.
The part almost nobody warns sellers about
Here is the catch, and it is the reason I never let a seller treat this decision lightly. Even with an escape clause keeping you technically on the market, your showings will usually taper off.
The moment you accept the condition, the way the listing displays changes. On the MLS and on most public platforms, your home starts showing as conditionally sold. And to a buyer scrolling listings, conditionally sold reads as gone. Many will not even book a showing on a home that looks like it is already spoken for.
It gets more discouraging once they understand the mechanics. A new buyer who does view your home and wants it does not get first right of refusal. They can submit an offer, but that offer triggers your escape clause, which sends the original buyer to the front of the line to firm up first. So the new buyer can do all the work, write a strong offer, and still lose the house to someone who was already there. A lot of buyers, once they realize that, simply move on to a listing where they actually have a clean shot.
So yes, the escape clause keeps you on the market on paper. But in practice, accepting the condition cools your listing's momentum, sometimes significantly. That is not a reason to say no. It is a reason to only say yes when the buyer's home is genuinely likely to sell, and quickly.
A real example from my side of the table
I represented sellers who received one of these offers. Everything about it looked fine on paper, but we had never seen the inside of the buyer's home and had no idea what price it would be listed at.
So we did not accept it as written. We required them to list their property first, at a price we could evaluate, before we would agree to the condition. That single requirement changed everything. It let my clients judge the actual likelihood of that home selling instead of guessing, and it forced a real conversation about pricing rather than a hopeful one.
It is not an aggressive move. It is just refusing to accept a risk you cannot measure. If the buyer is serious, listing is something they were going to do anyway.
Making it work
These conditions succeed when both sides are realistic. The buyer prices their home to sell rather than to dream. The seller understands they are accepting a calculated risk and protects themselves with an escape clause and a firm timeline. Everyone agrees on what happens if the first week or two comes up empty.
They fail when the buyer's home is overpriced, when nobody has discussed a price reduction plan, or when the seller accepts without asking any of the questions above.
If you are on either side of one of these right now, that is exactly the kind of situation worth talking through in detail before you sign anything. Every one of them is a little different, and the details are where the outcome lives.
