Here is a situation nobody prepares you for in real estate school: your seller is under contract, the ink is barely dry, and the phone rings. Another agent has a buyer. They want to submit a backup offer - and it is higher than the accepted one. Maybe significantly higher. Your seller looks at you with that specific expression you never want to see, the one that says, did we leave money on the table?
Welcome to one of the most uncomfortable positions in this business. Not because it is legally complicated - though it has layers - but because it is emotionally loaded for everyone in the room. Handle it wrong and you blow up an existing deal, create liability, and earn a reputation as the agent who cannot hold a transaction together. Handle it right and you cement your status as the professional who actually earns their commission.
What a Backup Offer Actually Is - and What It Is Not
First, let us get clinical for a second because clarity is your best friend here. A backup offer is a secondary contract that becomes active only if the primary contract falls apart. That is the whole mechanism. It is not a competing offer. It is not a renegotiation. It is not a signal that your seller can reopen negotiations with the first buyer. It is a contingency instrument - a line behind the first one at the grocery store.
The problem is that sellers do not always hear it that way. They hear dollar signs. They hear we should have waited. And if you are not steady and clear in this moment, the conversation spirals into territory that creates real legal exposure - tortious interference, breach of contract, misrepresentation. These are not abstract risks. Agents lose their licenses over what happens in this conversation.
So before you say anything else to your seller, you need to slow the room down. Your job right now is not to make them feel better about the backup offer. Your job is to make sure they understand exactly what they are looking at and what the rules of engagement actually are.
The Conversation You Have to Lead Before Emotion Takes Over
When a seller hears there is a backup offer at a higher number, their brain does something predictable - it subtracts the gap. If the accepted offer is at three-fifty and the backup comes in at three-sixty-five, they are already spending fifteen thousand dollars in their head before you finish your sentence. Your job is to interrupt that math before it runs away from you.
Here is what I tell my clients in that moment: You have a binding contract with a buyer right now. That contract has legal force and we are going to honor it unless it fails on its own terms. Full stop. Then I walk them through what legitimate backup offer acceptance looks like - we can sign it as a secondary position, it gives us a safety net if something goes wrong with the primary, and it absolutely does not give us permission to manufacture a reason to cancel on the first buyer.
That last part matters more than anything. Some sellers - and even some agents who should know better - start looking at the inspection period or the financing contingency like it is a door they can prop open just enough to let the first deal die. Do not go there. Do not let your seller go there. The language you use in this conversation is either protecting you or exposing you, and there is very little ground in between.
If the seller wants to accept the backup offer as a genuine secondary position, walk them through the paperwork clearly, explain the timeline, and document everything. That is a legitimate move. What is not legitimate is treating the backup offer as leverage against the first buyer - and you need to say that out loud, plainly, even if it is awkward.
How To Handle the Agent on the Other End of That Backup Call
Now let us talk about the agent who called you. Because how you respond to that call shapes everything that follows. The other agent is doing their job - they have a buyer and they are trying to create a position. Respect that. But you are the listing agent on an active contract and that role comes with obligations that run in a very specific direction.
What I do not do is have a long exploratory conversation about terms. I do not encourage them. I do not say things like well, if anything changes I will definitely call you. That kind of loose talk creates expectations you cannot deliver on without harming your existing client. What I do say is straightforward: we are under contract, I will present any written backup offer to my seller, and if they choose to accept it as a secondary position I will communicate that clearly and promptly.
Then I stop talking. Because the less you say in these calls, the better protected everyone is. If they submit something in writing, great - you have a document to work with and a process to follow. If they do not, the conversation is over and you move on.
Document the call. Write down the time, the agent, what was discussed. If anything in this transaction ever gets questioned later, your contemporaneous notes are your best evidence that you handled it cleanly.
Turning This Moment Into Something That Builds Your Reputation
Here is what most agents miss when the backup offer lands: this is actually a moment that can strengthen your relationship with your seller, not complicate it. Because if you navigate it with confidence and clarity - if you explain the rules, protect their interests inside those rules, and help them make a sound decision - they walk away thinking something important: my agent knew exactly what to do.
That is the reputation that builds a referral business. Not the agent who chases the highest number at any cost. The agent who held the line, kept the deal together, and still managed to explore every legitimate option the seller had. That agent gets called the next time. That agent gets sent the sister, the coworker, the neighbor.
When the transaction closes - whether with the original buyer or through a legitimate backup position - your seller should be able to say they trusted you completely in the hardest moment of the deal. That is the work. That is what we are actually doing here.
The backup offer is not a crisis. It is a test. And now you know how to pass it.
