You invite three estate agents to value your property. You're expecting broadly similar figures — after all, they're professionals. They have access to the same comparable sales data. They're looking at the same house.
Agent A: £575,000. Agent B: £625,000. Agent C: £595,000.
A £50,000 spread. Same property. Same day. Three supposed experts.
So what's going on? Why can't they agree? And more importantly — how do you find the honest number in all this noise?
The Psychology of Competitive Valuations
Here's what's actually happening when agents give you wildly different valuations: they're not valuing your property. They're competing for your business.
Most agents operate on a "win the instruction first, manage reality later" model. They know that sellers tend to instruct whoever gives the highest valuation — because that's what most sellers do. So they inflate their number to get ahead of the competition.
This isn't always malicious. It's simply how the industry has evolved. Agents who give honest valuations lose instructions to agents who tell sellers what they want to hear. Over time, candour becomes commercially inconvenient.
The agent quoting £625,000 probably isn't lying outright — they're thinking: "Price it high, generate some interest, reduce to £595,000 in a few weeks and still get the sale." They're not valuing what it's worth today. They're valuing what they think you'll accept listing it at.
How Comparable Sales Get Manipulated
Every agent will show you "comparable sales" to justify their number. Here's how the data gets shaped to fit the story:
The optimistic agent (£625,000) shows you the best sales in your area from the last six months — the house three streets away that sold for £640,000 (which had an extension yours doesn't), the flat that achieved £550,000 (ground floor with garden, not second floor like yours). They highlight the high points and gloss over the differences.
The realistic agent (£595,000) shows you genuinely comparable properties. Similar size, condition, location. Explains the differences honestly. Gives you a range, and tells you where you sit within it based on the specifics of your home.
The same data exists for everyone. But it's presented very differently depending on which story the agent wants to tell.
Finding the Honest Valuation
So you have three different numbers. How do you work out what's actually true?
Look at the average, not the highest. If you're seeing £575,000, £595,000, and £625,000, the realistic number is probably around £590,000–£600,000. The highest valuation is almost always inflated to win the instruction.
Make each agent justify their number with specifics — not vague statements like "the market's strong," but actual comparable sales. Which properties sold for what? How are they similar to yours? How are they different?
Check their comparable sales yourself. All sold property data is public. Look up the properties they're citing on Rightmove. Do those sales actually support the valuation? Or has the agent overlooked some rather inconvenient differences?
Ask what they've actually sold recently. Any agent can quote high numbers. Ask what properties they've personally sold in your area in the last six months, and what they achieved versus the asking price. That tells you how accurate their valuations really are.
Listen carefully to the agent who explains the downsides. An agent who points out what might limit your price, or what buyers are likely to negotiate on, is probably being straight with you. The agent who says everything's wonderful and you'll definitely achieve £625,000 probably isn't.
Why This Matters
Getting the valuation wrong costs you time and money — sometimes significant amounts of both.
Price too high and you'll attract initial curiosity, but serious buyers — who have done their research — won't engage. After six to eight weeks without offers, you reduce to where it should have been priced from the start. Except now your property looks stale, and buyers start wondering what's wrong with it.
Price too low and you might sell quickly — but you've left real money on the table.
The honest valuation gets you sold at the best achievable price within a reasonable timeframe. That's the whole point.
The Agent Worth Working With
Some agents do give honest valuations, even when they know it might cost them the instruction. They give a realistic range rather than a single flattering figure. They explain both optimistic and cautious scenarios. They show you comparable sales and acknowledge the differences honestly. They talk about what might limit your price, not just what might increase it. They don't promise outcomes they can't control.
These agents don't always win instructions immediately, because sellers often go with whoever quoted highest. But their properties sell efficiently — which is why their clients refer them, come back, and don't end up on the market for six months wondering where it all went wrong.
At Expose, our instruction-to-sale conversion rate sits at 92%. That's not a coincidence. It's what happens when you price correctly from day one.
What You Should Do
Get at least three valuations. You need multiple data points to identify outliers.
Ask detailed questions. Don't just accept the number. Make them explain it. Ask about comparable sales. Ask what might limit the price. Ask what their strategy would be if it doesn't sell at this level within six weeks.
Check their track record. Look at their Rightmove profile. What have they actually sold? How long did properties take? What was achieved versus the asking price?
Be honest with yourself. If two agents say £595,000 and one says £625,000, you probably want to believe the highest figure. But wanting to believe something doesn't make it true.
The Uncomfortable Reality
Three agents, three different prices. Statistically, at least two of them are wrong — and it's almost certainly not the highest one that's right.
The valuation process is imperfect because agents have conflicting incentives. The system would work better if sellers chose agents based on track record, marketing quality, and honest communication rather than who quoted the highest number. But most don't — and so the cycle continues.
You can't change the industry. But you can be a smarter seller: make your decision based on evidence rather than optimism, and you'll almost certainly end up with a better outcome.
