The call usually comes from the agent, sometimes from the solicitor. The buyer’s pulled out. Weeks, sometimes months, of viewings, negotiation, surveys and solicitors’ correspondence, and the sale simply isn’t happening.
In a standard sale in England and Wales, this is a legal reality every seller is exposed to until contracts are exchanged. An accepted offer is not legally binding before exchange, so either side can usually withdraw without being contractually committed to complete the sale, although both may already have incurred costs. GOV.UK explains that the transaction becomes legally binding when contracts are exchanged.
If contracts have already been exchanged, the position is very different. A buyer trying to withdraw after that point may be in breach of contract, and you should speak to your conveyancer immediately rather than treating it as an ordinary fall-through.
The instinct after a pre-exchange collapse is usually to relist immediately and treat it as bad luck. Sometimes that’s exactly right. But the more useful first move is slower and more specific: work out why the sale actually collapsed, because the right response depends almost entirely on the cause.
First, how common is this, really?
More common than most sellers expect, although there is no single official national fall-through rate and industry datasets measure the market in different ways.
Research published by Connells Group in 2026 found that 37% of the agreed sales in its analysis for 2025 did not reach completion. Its figures showed a notable difference between freehold transactions, at 36%, and leasehold transactions, at 43%, with leasehold sales also tending to fail later in the process.
Other datasets produce lower figures because they measure transactions differently. TwentyCi’s Property & Homemover Report for Q1 2026 reported a substantially lower fall-through rate than the Connells analysis. The figures are not directly comparable, but the useful conclusion for a seller is the same: a significant minority of agreed sales never make it to completion.
That matters less as a statistic than it does as perspective. A collapsed transaction feels highly personal when it is your months of work and your onward move at stake, but it does not necessarily mean there is something fundamentally wrong with your property or the way you have handled the sale.
Work out which of three things actually happened
The buyer. Their circumstances changed, their mortgage application failed, or they simply had a change of heart. This is the category least connected to anything about your property or your price, and generally the one that warrants the quickest, least dramatic response.
The chain. A linked transaction elsewhere collapsed — someone else’s buyer pulled out, someone’s sale fell through — and it took yours down with it, through no fault of the property or the price. It is worth finding out from your agent specifically where in the chain the break occurred and whether your own buyer has actually withdrawn or is still trying to proceed.
The property. A survey turned up something the buyer wasn’t prepared to proceed with, a lender valued the property below the agreed price, or a legal or title issue surfaced during conveyancing. This is the category that most directly affects what you should do before going back to market, because the underlying problem may surface again during the next buyer’s due diligence.
These categories aren’t always perfectly clean. A buyer might describe their decision as cold feet when a survey finding or financing problem was really what changed their mind. Ask your agent for whatever detail they have rather than accepting a vague explanation at face value.
In the first day or two, the priorities are fairly simple: establish the real reason for the withdrawal, tell the agent handling your onward purchase immediately, find out whether the original buyer is genuinely gone or trying to rebuild their chain, and ask your selling agent which previous viewers or backup buyers can be contacted. Only after that does it make sense to decide whether the property needs work, the price needs revisiting or the existing buyer is worth waiting for.
If it was the buyer or the chain
There’s usually no reason to start changing the property or cutting the price simply because one buyer’s circumstances changed. Ask your agent whether any previously interested buyers — people who viewed but didn’t offer, lost out during negotiations or registered interest after the sale was agreed — are worth re-approaching. A warm restart with someone who already knows the property can be quicker than beginning again from zero.
A broken chain requires slightly more judgement. If your buyer has lost their own buyer but still wants your property, establish what that actually means. Are they putting their home straight back on the market? Could they proceed without selling? How quickly are they realistically likely to rebuild their chain? You do not necessarily have to abandon an otherwise committed buyer, but neither do you have to leave your own move indefinitely dependent on them finding another purchaser.
Your agent can continue talking to backup buyers while you decide how much time, if any, you are prepared to give the original buyer.
If you’re buying another property yourself, speak to the agent handling your onward purchase as soon as possible. A sale falling through does not automatically mean your purchase has to collapse as well. The seller above you may be prepared to wait while you replace your buyer, particularly if the rest of the chain is well advanced. What matters is communicating the position before uncertainty turns into assumptions elsewhere in the chain.
Nor should a fall-through automatically trigger a price reduction. If somebody further down the chain withdrew or your buyer’s circumstances changed, lowering the asking price may solve nothing and simply cost you money. Price deserves a fresh look when the reason for the failure points towards the property itself, buyer resistance to the agreed figure or evidence from the valuation and comparable sales.
If it was the property
This is where the response needs to be more deliberate.
If the buyer’s lender valued the property below the agreed price, do not automatically treat that as proof that the property was overpriced. A mortgage valuation is primarily undertaken for the lender rather than as a detailed assessment for the buyer; RICS distinguishes clearly between a lender valuation and a residential survey.
But neither should a down-valuation simply be dismissed. Find out whether the sale failed because of the valuation itself or because the buyer could not — or would not — bridge the gap between the mortgage available and the agreed price. Then review genuinely comparable recent sales with your agent before deciding whether the original asking price still holds up.
If a buyer’s survey uncovered a genuine defect, resist the temptation to simply relist and hope it does not come up again. Another surveyor may identify the same issue, particularly if it is significant.
You may not have a right to the buyer’s full survey report, but your agent can often establish what finding caused the concern. Depending on the issue, getting an appropriate second opinion or repair quotation before returning to market can put you in a much stronger position. Sometimes the sensible answer will be to carry out the work; sometimes it will be to obtain evidence showing why the problem is less serious than first suggested; and sometimes it will be to price the property with the issue understood.
The important point is that the second sale should not begin with everyone pretending the first problem never happened.
If the issue was legal or related to the title, that’s a conversation for your conveyancer rather than something to try to solve through pricing or presentation. Ask whether the issue can be resolved now and whether the necessary evidence can be assembled before another buyer reaches the same point in conveyancing.
Should you relist with the same agent?
A fall-through on its own is not a particularly good reason to change estate agents. Buyers withdraw for reasons an agent cannot control. The more useful question is whether the agent did what could reasonably have been done to reduce the risk: how thoroughly was the buyer’s financial position checked before the offer was recommended, was the chain understood, was the transaction actively progressed after the sale was agreed, and were warning signs identified early?
If the agent handled those things well, changing them because a buyer’s mortgage failed or somebody further down a chain withdrew may achieve very little. If you do want to switch, however, check your existing agreement before instructing another firm. Notice periods, sole-agency terms, sole-selling-rights clauses and previous introductions can all matter. Propertymark’s consumer guidance on estate-agent contracts and fees explains why the terms of the agreement need checking before moving to another agent.
Changing agent can refresh the marketing, but it does not erase the reason the first transaction collapsed. Whether you stay or move, this is a reasonable point to reconsider the photography, description, presentation and asking price rather than automatically putting exactly the same listing back online.
What happens to the money you’ve already spent?
This is easily overlooked when the immediate concern is finding another buyer. The costs of a collapsed sale are not necessarily confined to the property you are selling either. If you have an onward purchase, you may already have paid for conveyancing work, searches, a survey, mortgage-related costs or other services connected with that transaction.
Do not assume everything is either lost or automatically transferable. Ask each provider what remains payable, what work can be reused and what would need paying for again if your onward purchase survives or you move on to another property. Conveyancing firms, surveyors, mortgage brokers and other providers operate under different terms, and the answer can depend on how far the work had progressed when the transaction stopped.
The same applies to your sale. Your conveyancer may already have prepared title information and contract documents, leasehold paperwork may have been assembled, and enquiries from the first buyer may have exposed issues that can now be dealt with before somebody else asks the same questions. A failed transaction can at least leave the next one better prepared if that work is used properly.
Before you go back to market
A short, honest assessment tends to serve better here than a rushed relisting.
Has the actual cause been identified, rather than assumed? If the problem came from the property, is there anything worth repairing, investigating or documenting before another buyer’s due diligence reaches the same point? If price or valuation played a part, does the figure still hold up against genuinely comparable recent transactions? If the buyer was the problem, is there actually any reason to change the price at all?
And look at what the failed transaction has left behind. Ask your conveyancer what can be retained or prepared for the next buyer rather than assuming the entire conveyancing process has to start again from nothing.
None of this needs to turn a fall-through into a lengthy post-mortem. But a sale that collapses for a reason nobody properly understood, and gets relisted unchanged in the hope the next buyer is simply luckier, has a habit of running into the same problem twice.
