My buyer needs to sell their home first. Should I accept?
Published 11 June 2026 · 5 min read · By Evren Ergin
Accepting an offer from a buyer who still has to sell their own home is common and often works out fine, but it adds a link of risk you can manage rather than fear. The trick is to treat it as a 'yes, if' rather than a flat yes: accept in principle, keep marketing, and judge the buyer by how far along their own sale already is.
TL;DR
- •A buyer who needs to sell first is part of a property chain, and chains are normal in the UK market.
- •The real risk is delay and collapse, so judge the buyer by how far along their own sale is, not by how keen they sound.
- •Chain breaks caused about 1 in 8 UK sale fall-throughs in early 2026, when roughly 24% of all agreed sales fell through.
- •You can say yes and still protect yourself: stay on the market until their sale is agreed, and keep your own spending in step with theirs.
Start from the calm fact: most homes in the UK are sold inside a chain, and plenty of those chains complete perfectly well. A buyer who needs to sell first is not a problem to refuse on sight. It is a situation to size up. Once you know exactly where their own sale stands, the decision is usually clear.
What is a property chain, and why does it matter?
A property chain is a line of linked sales where each move depends on the one below it completing. If your buyer has not yet sold their home, their purchase of yours cannot complete until their sale does, and their buyer's sale, and so on down the line. A proceedable buyer is one who can complete now, with nothing left to sell. The further your buyer is from being proceedable, the more links have to line up before you get your money and your move.
How do I decide whether to accept?
1. Ask exactly where their own sale is
There is a world of difference between 'we are about to list' and 'we exchanged last week'. Ask plainly: not yet on the market, on the market with no offer, under offer, or already exchanged on their sale.
2. Map the chain below them
Find out how many links sit beneath your buyer and whether anyone in the line is a first-time buyer or cash buyer who can anchor it. A short, anchored chain is far safer than a long one full of ifs.
3. Keep marketing until their sale is agreed
Accept the offer subject to them getting their own sale agreed, and keep your home visible until that happens. Most agents call this staying on the market; it costs you nothing and keeps a backup buyer warm.
4. Set a check-in date and a walk-away point
Agree a date by which you expect their sale to be agreed, and a point at which you will go back to other buyers. A deadline turns a vague wait into a managed one.
5. Move your own spending in step with theirs
Instruct your solicitor early because it is cheap and keeps momentum, but hold the larger, harder-to-reverse costs until their sale is agreed and progressing.
6. Use your agent to keep the chain honest
Ask for regular chain updates, not just on your sale but on every link below. The first sign of a chain problem is usually one link going quiet.
How ready is your buyer's own sale?
Reading where your buyer stands
| Their stage | Risk level | What to do |
|---|---|---|
| Not yet on the market | High | Keep marketing, set a clear deadline, do not take your home off sale |
| On the market, no offer yet | High | Keep marketing, treat it as interest rather than a firm deal |
| Under offer on their sale | Medium | Proceed with care, ask about the buyer below them |
| Exchanged on their sale | Low | They are effectively proceedable, safe to commit |
What is normal, and what is a red flag?
It is normal for a chain to move in fits and starts and for a few weeks to pass with little visible progress. The genuine red flags are different: a buyer who will not say where their own sale is, a buyer not yet on the market who wants you to take yours off sale, or a link below that nobody can get an update on. Read commitment by what each party has spent and instructed, not by how enthusiastic they sound. A solicitor instructed, a mortgage application in and a survey booked are real; warm words are not.
- Safe to lean in: their sale is under offer or exchanged, the chain is short, and updates flow freely.
- Stay cautious: their sale is agreed but the chain is long, or one link keeps going quiet.
- Hold back: they are not yet on the market and are asking you to commit costs or come off sale first.
The decision, and the timeline, belong to you. ValuQ gives UK homeowners free, side-by-side property valuations from competing local estate agents, so you can price and position your home to attract proceedable buyers and judge any chain from a position of strength rather than hope.
