A buyer offered but needs to sell first. Should I accept?
Published 9 July 2026 · 6 min read · By Evren Ergin
Yes, you can accept an offer from a buyer who still has their own home to sell, and plenty of these sales complete happily. The trick is to judge the offer on how far along their own sale is, not on how keen they sound, and to keep your big decisions gated on real progress.
TL;DR
- •A buyer who has to sell their own home before they can buy yours is called a non-proceedable buyer, and their offer depends on a chain forming beneath you.
- •These offers can be perfectly good, but they carry more risk of falling through than a chain-free buyer with cash or a mortgage in place.
- •Judge the offer by how far the buyer's own sale has progressed, not by their enthusiasm.
- •You can accept while keeping your home on the market until the chain firms up, which protects you if their sale stalls.
This is one of the most common questions a seller faces, and it is a fair worry: you have an offer you like, but the buyer cannot actually complete until they have sold their own place. The offer is real, yet it comes with a condition attached. The calm way through is to size up the risk properly, then accept on terms that keep you in control.
What does a non-proceedable buyer mean?
A proceedable buyer is one who can buy right now: a cash buyer, or someone with a mortgage agreed and no home to sell first. A non-proceedable buyer is someone whose purchase depends on selling their own property first. When their home sells, and the buyer below them lines up, you have a chain. A chain is simply a run of linked sales that all have to complete on the same day, and the longer it is, the more places it can break.
How risky is it to accept an offer that depends on a chain?
Riskier than a chain-free buyer, but far from doomed. Roughly one in four agreed UK sales fell through in 2025, a rate that has carried into 2026, and broken chains are one of the recognised causes. The exposure is real, but most chains that form do go on to complete. The point is not to refuse these buyers; it is to read how solid their end of the chain is before you rely on it.
How to read your buyer's position
| Where the buyer's own sale is | What it tells you | Risk |
|---|---|---|
| Not yet on the market | They are keen but nothing is underway; the chain does not exist yet | High |
| On the market, no offer | Genuine intent, but their sale could take months or need a price cut | Medium to high |
| Offer accepted on their home (SSTC) | A chain is forming; ask how far below them it goes | Medium |
| Sold subject to contract with a short, proceedable chain below | The strongest version of this offer | Lower |
How should I decide whether to accept?
1. Ask exactly where their sale is up to
Have your agent confirm in plain terms whether the buyer is on the market, under offer, or further along, and get it in writing.
2. Find out how long the chain is
Ask how many linked sales sit below your buyer; a short chain of proceedable people is far safer than a long one.
3. Compare it against your other options
Weigh this offer against any proceedable offers or the chance of holding out; a slightly lower chain-free offer can be worth more than a higher one that may never complete.
4. Line up your own solicitor early
Instructing a conveyancer is cheap and keeps momentum, and it costs you little if the sale does not run.
5. Accept on a continue-to-market basis
Agree with your agent that you will keep marketing the home until the buyer's chain is complete, so you are not sitting exposed.
6. Set a review date
Agree a date with the agent to check the buyer's progress; if their sale has not moved by then, you can reconsider without drama.
How do I protect myself if I accept?
The safest habit is to read a buyer's commitment by what they have actually done, not by what they say. Words are free; instructing a solicitor, ordering searches, booking a survey, and getting an offer on their own home cost time and money, and those are the signs of a buyer who means it.
- Move in step with the buyer, not ahead of them; do the cheap, reversible things first and gate the big spends on their progress.
- Do not take your home fully off the market until the chain below you is firm; a continue-to-market arrangement is your safety net.
- Hold off on booking removals, paying for a leasehold information pack, or committing to your own onward purchase until the buyer is financially committed.
- Keep talking to your agent weekly; a buyer whose sale never seems to move is telling you something.
Is a cash buyer always better than one who needs to sell first?
Usually yes on certainty, because a cash or mortgage-ready buyer can proceed straight away with no chain beneath them. But a strong, short chain can still be a good sale, and a chain-dependent buyer might offer more. Weigh price against the risk of the chain breaking.
Can I keep my house on the market after accepting?
Yes. Accepting an offer is not legally binding until you exchange contracts, so you can agree with your agent to keep marketing until the buyer's chain completes. Be open that you are doing this so nobody feels misled.
How long should I give a buyer to sell their own home?
There is no fixed rule, but agree a realistic checkpoint up front, for example four to six weeks, and review their progress then. If their own home is not even under offer by the checkpoint, it is fair to reconsider.
