Should I instruct my solicitor before my buyer's mortgage offer?
Published 4 June 2026 · 6 min read · By Evren Ergin
Yes, instruct your own solicitor now, because lining one up the moment you accept an offer is cheap, keeps your sale moving, and commits you to nothing risky. What you should hold back is the bigger, harder-to-reverse spending, and taking your home off the market, until your buyer has shown real financial commitment.
TL;DR
- •Instructing your own solicitor early is low cost and keeps your sale moving, so there is no reason to wait for the buyer's mortgage offer to do it.
- •Gate the expensive, hard-to-undo moves on the buyer's commitment, because around 1 in 4 agreed UK sales fall through and most collapses happen in the first few weeks (TwentyEA, April 2026).
- •Read a buyer's seriousness by what they have spent and instructed, not by what they say.
This is one of the most common worries in the early weeks of a sale. You want to keep things moving, but you do not want to pour money and momentum into a buyer who may walk away. The calm answer separates the cheap, safe steps from the expensive, risky ones.
Should I instruct my solicitor before the mortgage offer?
Instructing a solicitor means formally appointing a conveyancer to handle the legal side of your sale. Doing it as soon as your offer is accepted is cheap and reversible, and it keeps your sale moving while the buyer arranges their mortgage. Waiting until the buyer's mortgage offer arrives only slows your own side down for no real protection.
How long does a buyer's mortgage offer take?
A mortgage offer is the lender's formal, written commitment to lend, issued after the buyer's application, credit checks, and a lender valuation. It usually arrives a few weeks into the process, not on day one, so a quiet first fortnight is normal rather than a warning sign.
Roughly when each stage happens after an offer is accepted
| Stage | Typical timing | What it tells you |
|---|---|---|
| You instruct your solicitor | Week 1 | Cheap, reversible, keeps your sale moving |
| Buyer applies for their mortgage | Weeks 1 to 3 | First real sign of intent |
| Lender valuation and buyer's survey | Weeks 2 to 6 | The buyer is now spending money |
| Buyer's mortgage offer issued | Weeks 3 to 6 | Strong proof of financial commitment |
| Exchange of contracts | Weeks 8 to 12 | The sale becomes legally binding |
Conveyancing usually takes about 8 to 12 weeks from offer to completion, so the wait for a mortgage offer is a normal part of that window, not a delay to panic over.
What is normal, and what is a red flag, while you wait?
Reading your buyer in the early weeks
| Normal | Red flag |
|---|---|
| A quiet first week or two while the mortgage application goes in | Weeks pass with no mortgage application started |
| The buyer instructs a solicitor and orders searches | The buyer keeps delaying instructing anyone |
| Sensible questions about fixtures, boundaries, or timing | Repeated requests to lower the price with no survey to justify it |
| The buyer's agent can confirm progress when asked | Nobody can tell you whether the buyer has even applied |
How do I protect myself without losing the sale?
The key idea is the imbalance in the early weeks. Sellers often get excited and commit money first, by paying for legal packs, ordering their own searches, and taking the home off the market, while the buyer has spent almost nothing and can still change their mind. Move in step with your buyer, not ahead of them.
How to read a buyer's true commitment
| What shows real commitment | What does not |
|---|---|
| A solicitor instructed and paid | Saying "we love it" |
| A mortgage application submitted | A verbal promise to apply soon |
| Searches ordered and a survey booked | Still viewing other homes |
| A mortgage offer issued in writing | An agreement in principle alone |
What should I do, step by step?
1. Instruct your solicitor now
Appoint your conveyancer as soon as the offer is accepted, because it is inexpensive and keeps your sale moving.
2. Ask for proof the buyer has applied
Have your agent confirm the buyer has submitted a mortgage application, not just an agreement in principle.
3. Watch for their solicitor and searches
A buyer who has instructed a solicitor and ordered searches is spending money, which is the clearest early sign of intent.
4. Hold the big spends back
Wait on costly leasehold or management packs and your own searches until the buyer's mortgage offer is in.
5. Stay quietly available until exchange
Keep the home reachable and come fully off the market only once the buyer is financially committed.
6. Set a weekly check-in
Agree a short weekly update with your agent so any stall is caught in days, not weeks.
Is an agreement in principle the same as a mortgage offer?
No. An agreement in principle is an early indication of how much a lender might offer, based on a soft check. A mortgage offer is the lender's formal written commitment to lend, issued after a full application and a valuation, and it is far stronger proof that your buyer can complete.
Should I take my house off the market straight away?
Not on day one. Lining up your own solicitor keeps momentum, but coming fully off the market is the move to gate on the buyer's commitment, ideally once their mortgage offer is issued, so you are not exposed to a buyer who has spent nothing.
ValuQ gives UK homeowners free, side-by-side property valuations from competing local estate agents, so the agent you choose is one who manages your sale well, not just the one who quotes the highest figure. The timeline and the spending decisions belong to you, and moving in step with your buyer keeps them that way.
Read a buyer by what they have spent, not by what they have said. Money committed is the only promise that holds.
