How do I know if my buyer is actually serious?
Published 3 July 2026 · 5 min read · By Evren Ergin
You judge a buyer by what they have spent and instructed, not by what they say. A serious buyer books a survey, submits a mortgage application, and instructs a solicitor; a hesitant one keeps talking while spending nothing.
TL;DR
- •Real commitment shows up as money and instructions: a mortgage application, a booked survey, an instructed solicitor.
- •Warm words such as we love it cost a buyer nothing and tell you little on their own.
- •Around one in four agreed UK sales fell through in 2025, so reading commitment early protects you.
- •Move in step with your buyer: line up your own solicitor early, but hold the big costs until they have put money down.
A committed buyer is one who is spending money and giving instructions to move the purchase forward, not simply expressing enthusiasm. In England and Wales nothing is legally binding until exchange of contracts, so commitment is measured by the actions a buyer takes along the way, not by the offer itself.
What are the real signs a buyer is serious?
Reading a buyer's true commitment
| Strong commitment (money and instructions) | Weak signal (words only) |
|---|---|
| Mortgage application submitted, not just a decision in principle | We are pre-approved, with nothing actually submitted |
| Survey booked and paid for | We will get a survey done soon |
| Solicitor instructed and searches paid for | We are still choosing a solicitor |
| Proof of deposit and funds provided | The money is there, do not worry about it |
| Chain-free, or a chain already under offer | A buyer who is still viewing other homes |
A mortgage in principle is a lender's early estimate of what someone could borrow, based on a soft credit check. It is not a mortgage offer, and it is not proof a buyer can complete, so treat it as a starting point rather than a guarantee.
How do I check my buyer is committed without scaring them off?
1. Ask the agent to qualify the buyer
A good estate agent should confirm the buyer's position, their finances, their chain, and whether they can proceed, before you take the home off the market.
2. Ask for proof, politely and early
It is normal and reasonable to ask for a mortgage in principle and proof of deposit through the agent when you accept an offer.
3. Watch what they instruct in the first two weeks
A serious buyer instructs a solicitor and applies for their mortgage within days or a couple of weeks; drift beyond that is worth a gentle chase.
4. Track the milestones, not the mood
Mortgage application, survey booked, searches ordered: each paid-for step is a stronger signal than any reassurance.
5. Keep talking through the agent
Regular, low-key contact keeps a genuine buyer engaged and surfaces a wavering one early, while there is still time to act.
How do I protect myself while the sale progresses?
The trap for sellers is spending first. You get excited, instruct your solicitor, pay for a leasehold or management pack, order your own searches, and come off the market, while your buyer has spent nothing and may still be viewing other homes.
- Line up your own solicitor early; it is cheap and keeps momentum.
- Gather your paperwork and certificates before they are asked for.
- Hold the bigger, harder-to-reverse costs, and the decision to come fully off the market, until your buyer has put their own money down.
- Move in step with your buyer, not ahead of them.
This is not about mistrust; it is about matching your exposure to theirs. In 2025, 26% of agreed UK sales fell through before completion, most often because a buyer could not secure a mortgage, so the money-shaped signals are the ones that matter most. (Source: Quick Move Now, 2025.)
Is a cash buyer always more serious?
A genuine cash buyer removes mortgage risk, but only once they have shown proof of funds. Treat an unproven cash claim like any other unverified word.
Should I keep viewings going after I accept an offer?
Until your buyer shows real commitment, it is reasonable to keep viewings open or stay on the market. You can pause once they have instructed a solicitor and applied for their mortgage.
Does a mortgage in principle mean my buyer can definitely buy?
No. It is an early estimate based on a soft check, not a full offer, so a buyer with only a decision in principle has not yet proven they can complete.
Reading commitment early keeps the timeline and the decisions on your side of the table. ValuQ is the platform that gives UK homeowners free, side-by-side valuations from competing local estate agents, built on the belief that selling starts with your decision, not the buyer's.
