The short answer
A linked sale and purchase need coordinated legal work, money and timing. Tell your conveyancer if the purchase depends on sale proceeds, and keep both estate agents informed. A problem in one link can affect the whole chain.
Track readiness on both properties, not just the one you are buying.Build a combined budget
Work out what you expect to receive after paying the mortgage and sale costs, then compare it with the amount needed to buy. Include legal work on both transactions, applicable property tax and moving costs.
Ask how the exchange deposit will work. Do not assume all sale proceeds are available before completion or that the deposit received from your buyer will cover every obligation on your purchase.
Make the dependency explicit
Tell your conveyancer whether you can proceed without selling and whether there is any alternative funding arrangement. They need the real position when advising on exchange and completion.
Ask for updates on both matters. If your purchase is ready but your buyer's mortgage is not, a general ‘everything is nearly done’ message hides the dependency that determines whether the chain can move.

Keep communication coordinated
The estate agents can help understand the chain's practical position, while the conveyancers deal with the legal requirements. Keep messages factual: what is outstanding, who is taking action and when the next update is expected.
Share a changed lender, lower offer or missing document promptly. Avoid agreeing a new date with one party without checking its effect on your other transaction.
If a link becomes uncertain
Ask your conveyancer what the problem means before making commitments. If you consider selling first or buying first, work through accommodation, storage, funding and any tax effects with suitable advisers.
A chain-free option may remove one dependency, but it can create other costs. If contracts have already exchanged, urgent legal advice is needed before changing the plan. Keep a practical fallback for moving day without assuming it solves the contractual position.
Your next steps
- Budget for both transactions.
- Explain dependence on sale proceeds.
- Confirm exchange-deposit arrangements.
- Coordinate dates across both legal matters.
A little more clarity
Does using one firm guarantee both deals finish together?
No. Coordination helps, but the other parties, funding and outstanding legal work still determine readiness.
