Counter-Offer: The Response Deadline Is Leverage, Not Paperwork

On a purchase offer, one box asks how long the offer stands. It usually gets filled in within seconds, out of habit, while it decides who keeps their options open and who has to commit. It is leverage in its own right, and it works before price is discussed. On what follows a refusal, see our piece on next steps after a rejected offer.

A contractual duration, never imposed

Start by clearing away a common misconception. The response deadline is not set by any rule. It is written into the document by whichever party presents the offer or counter-proposal, and it binds because both sides accepted it, not because a duration is prescribed. There is no standard deadline to invoke, and anyone telling you otherwise is inviting you not to exercise a choice that is yours.

The consequence is immediate: that box is negotiable like the price, like the possession date, like the conditions. The difference is that it costs the person using it nothing, which makes it the most underused lever on the form.

What the duration actually buys

The deadline sets how much time the other side has to compare, consult and seek alternatives. A seller holding an offer with a long window can circulate it, draw out a second offer, let a scheduled showing go ahead. With a short window, they decide on what is in front of them. What is at stake here is not the amount, it is the capacity to shop the offer.

Which is why duration matters more in some configurations than others. On a freshly listed property drawing traffic, every extra hour granted to the seller carries real value for them. On a property listed a long time with no movement, extending the window gives them little, since they have nobody to play the offer against. The same number of hours does not weigh the same across files.

A short deadline cuts both ways

A buyer who shortens the window limits shopping time, which is the intended effect. But it also produces two effects they did not choose. A seller may fail to reach their adviser, their spouse or their notary inside the window, and refuse by default rather than by decision. And a visibly tight duration reads as pressure, which puts some sellers off enough to colour their answer.

The actual calendar then matters, and it is routinely overlooked. A window spanning a night, a weekend or a holiday does not deliver the usable time its nominal length suggests. Counting in business hours rather than clock hours avoids setting a deadline that looks reasonable and, in practice, leaves almost nothing.

Two clocks not to confuse

The response deadline frames acceptance of the offer. Condition periods, financing or inspection for instance, run after acceptance on their own schedule. Two separate clocks, and shortening the first accelerates nothing about the second.

The classic error is compressing the response deadline to look decisive without having checked that the condition periods that follow can be met. A buyer can commit faster than they can perform, then find themselves asking for an extension days after advertising their speed. The credit earned at signing is spent in full.

What expiry does

Past the deadline, the offer stops binding the party who made it: it lapses and can no longer be accepted as it stands. A late acceptance does not restore the deal, it is a fresh proposal for the other side to accept or refuse. In other words the roles flip, and the party who was in a position to answer now has to wait for one.

The precise mechanics sit in the form used and should be confirmed with the broker on the file, who can also address valid delivery methods and the exact moment a response counts as received. Those technicalities sometimes decide whether an acceptance arrived in time, and they are not something to guess at.

A duration to choose at every round

Each counter-proposal carries its own deadline, and nothing requires reusing the previous one. That is often where the window tightens as exchanges continue, sometimes without anyone deciding it. Making that move deliberately changes the character of the negotiation: you are choosing to give the other side room to think, or to take it away, and you know why.

Before filling in the box, three questions suffice. How much time does the other side need to decide properly, given who they must consult. What shopping does this window allow them, and am I comfortable with that. And does the window I am proposing contain genuinely usable hours, or does it run through a night and a weekend.
