A backup offer puts you next in line if the accepted deal on a property falls apart. It is a real contract rather than a waiting-list entry, and the difference matters because you can end up committed to a home you have started moving on from.
What second position means
A seller with an accepted contract can also accept a second offer, held in reserve.
If the first deal collapses, your backup moves into first position and becomes the live contract on that property. Nothing happens while the first deal is alive and progressing. Everything happens the moment it fails.
That structure is useful when you genuinely want a specific home. Deals do fall apart, most often over financing, inspection findings, or what turns up in the strata documents. We have watched backups turn into completed purchases more than once.
The commitment buyers underestimate
Here is where first-time buyers get caught. A backup offer reads like optionality and behaves like an obligation.
You are signing a contract that goes live on an event you do not control. Meanwhile you are, sensibly, continuing to look at other properties. If you write an offer on something else while your backup is outstanding, you can create a situation where you are bound on two homes at once.
That is the conversation to have with your agent and your lawyer before you sign, not after you find something better. It is a foreseeable problem with a manageable answer, provided you raise it in time.
Three things to confirm in writing
Ask for all three, and get the answers in the document rather than in conversation.
Can you withdraw while in second position? Some backup offers include a right to revoke on written notice while the first deal is still alive. Some do not. If yours does not, you may have to wait on a stranger's mortgage approval before you can move on.
When does your subject period start? It should run from the moment the offer moves into first position. If the clock runs from signing, your inspection and financing conditions can quietly expire while you wait, leaving you with a firm contract and no protection. Our subject removal guide covers what those conditions do.
When is the deposit due? Some backups defer the deposit until the offer goes live. A deposit that triggers on short notice is a cash-flow problem, and our deposit versus down payment guide explains why the timing is not a detail.
Ask what position you are in
A seller can hold more than one backup, in order.
Second position is a genuine possibility. Third is closer to a formality, because two separate deals have to fail before yours is live. Ask directly, and factor the answer into how much of your attention this property deserves.
What the seller will and will not share
A seller may tell the first buyer that a backup exists. That knowledge can motivate a buyer to remove subjects, which is part of why sellers like holding one.
Your terms stay confidential, the same way the first buyer's terms are confidential from you. Our multiple offers guide covers that asymmetry in more detail. You will not learn why the first deal is at risk, or what it would take to be preferred.
How this differs from simply waiting
You do not need a backup offer to buy a home whose deal collapses. When a deal fails, the property usually comes back on the market and you can write then.
What the backup buys you is priority, and the cost is a commitment during the wait. So the honest test is whether you would be upset to see this property relist and sell to someone else in a weekend. If yes, a backup with a clean withdrawal right is reasonable. If you are lukewarm, the commitment is the wrong trade.
Note that if your backup goes live and you then want out, BC's rescission period gives three business days with a fee of 0.25% of the purchase price. Our rescission guide has the detail, and it is a costly exit rather than a comfortable one.
What we tell buyers
Write a backup when you want that specific home and the document lets you step out while you wait. Skip it when you are writing one out of momentum after a loss.
In our experience the buyers who regret a backup offer are the ones who signed it the same afternoon they lost the house, while the disappointment was fresh. A week later they had found something they preferred and discovered they were not free to act. Read the withdrawal terms before you sign, and the whole structure becomes reasonable.
We are agents rather than lawyers, and none of this is legal advice. Have your lawyer or notary review the backup offer before you sign it.
Key takeaways
- A backup offer is a contract in second position that goes live if the first deal collapses.
- Confirm in writing whether you can withdraw while still in second position.
- Confirm that your subject period starts when the offer moves into first position, not at signing.
- Confirm when the deposit becomes payable, because short notice is a cash-flow problem.
- Ask what position you actually hold, since third position is a different proposition from second.
Frequently Asked Questions
What is a backup offer?
A backup offer is an offer a seller accepts in second position, behind an existing accepted contract on the same property. Nothing happens while the first deal is alive and progressing toward completion. If that first deal collapses, most often over financing, inspection findings, or strata documents, your backup moves into first position and becomes the live contract on the property. It is a real contract rather than a waiting-list entry, which is why the terms you sign matter before you commit to second position.
Does a backup offer bind me?
Yes, a backup offer can bind you, which is the part buyers underestimate. You are signing a contract that goes live on an event you do not control, the failure of the first deal, so read it as a real commitment rather than a placeholder. Meanwhile you are, sensibly, continuing to look at other properties, and writing an offer on something else while your backup is outstanding can leave you bound on two homes at once. Have your lawyer or notary review the backup offer before you sign it.
Can I keep looking at other homes?
You can keep looking at other homes while your backup offer is outstanding, but be careful about writing a second offer during that time. A backup offer is a contract that becomes active if the first deal on that property collapses, and you could end up bound to buy two properties at once. Raise the situation with your agent and your lawyer before you sign any other offer.
How do I get out of a backup offer?
Getting out of a backup offer depends entirely on what the document says, so read it closely before you sign rather than after. Some backup offer agreements include a right to withdraw on written notice while still in second position. If yours does not include that right, you may have to wait on someone else's financing to succeed or fail before you are free to act. Confirm this in writing with your agent and your lawyer before you sign, not once you have found a home you prefer.
Do I have to pay a deposit on a backup offer?
Whether you have to pay a deposit on a backup offer varies by agreement. Some backups defer the deposit until the offer moves into first position and becomes the live contract, while others require it sooner. Confirm the timing in writing before you sign, because a deposit obligation that triggers on short notice, right when the first deal collapses, is a cash-flow problem you want to see coming rather than discover in the moment.
How often does the first deal actually fall apart?
The first deal on a property falls apart more often than buyers expect, most commonly over financing, inspection findings, or what turns up in the strata documents. We have watched backup offers turn into completed purchases more than once, which is why the structure is worth using when the property genuinely suits you. In our experience, a backup is worth writing when you specifically want that home, and it is a poor fit as a general tactic on any property you are lukewarm about.
Do my subject conditions still apply?
Your subject conditions should still apply on a backup offer, and the timing is what to check carefully. Confirm whether your subject period starts when the backup moves into first position rather than from the day you signed it. If the clock runs from signing instead, your inspection and financing conditions can quietly expire while you wait for the first deal to collapse, leaving you with a firm contract and no protection when the backup finally goes live.
Will the seller tell the first buyer about my backup?
A seller may tell the first buyer that a backup offer exists, and that knowledge can motivate the first buyer to remove their subjects sooner. The contents of your actual offer stay the seller's confidential information, the same way the first buyer's terms are confidential from you. You will not learn why the first deal is at risk, or what it would take for the seller to prefer your terms over the ones already accepted.
Can there be more than one backup offer?
Yes, a seller can hold more than one backup offer, in a stated order. Second position is a genuine possibility, since only one deal has to fail before yours goes live. Third position is closer to a formality, because two separate deals have to collapse first. Ask your agent directly what position you actually hold, and factor the answer into how much attention and commitment this particular property deserves from you.
Is a backup offer worth it for a first-time buyer?
A backup offer can be worth it for a first-time buyer when the property genuinely suits you and the document lets you withdraw while you wait in second position. The honest test is whether you would be upset to see this property relist and sell to someone else in a weekend. If yes, a backup with a clean withdrawal right is reasonable. The risk is signing a binding commitment on a home you have already half moved on from after losing it once.
