Why the Highest Valuation Is Not the Best Valuation

If you have had three estate agents value your house and one came in much higher than the others, here is the honest answer to what is going on: the highest valuation is very often a sales pitch, not a professional opinion of what your home will actually sell for. It is designed to win your instruction, because some agents know that the biggest number is the one most likely to get their board outside your house. Understanding this one thing can save you months and thousands of pounds.

A valuation is not a price. It is a prediction of what a real buyer will agree to pay. And a prediction that is too high does not put more money in your pocket. It does the opposite.

What overpricing actually costs you. The most interest your home will ever attract is in the first two weeks on the market. That is when every buyer who has been watching your area sees your home arrive, fresh. If your price is too high, those buyers scroll past, and you have spent your best two weeks of attention on nobody. Weeks later, when you reduce, the fresh buyers have already moved on and bought elsewhere, and your home now looks like the one that has been sitting. You do not calmly come down to the right price. You limp down past it, often ending below what a correct price on day one would have achieved.

The evidence that a correct price works. Rightmove reported that around 74 percent of homes that sold in 2026 sold with no reduction to the asking price. Read that the other way: the homes that get reduced are the minority, and they are usually the ones that were overpriced at the start. A correct price is not a cautious price. It is the one that gets you sold without the rescue mission.

How to spot the honest number. Ask each agent one question: which three sold and completed houses did you base this valuation on? A confident, honest agent will show you comparable homes that actually sold, near you, recently. An agent who guessed high to win you will get vague, or point at asking prices, which prove nothing. The evidence is the tell.

Why an honest agent tells you a lower number. It costs them. An agent who quotes you a realistic figure, when the agent down the road quoted more, risks losing your instruction to the higher number. Some of us are willing to do that anyway, because a reduction in six weeks helps nobody, and because the reputation you build by telling the truth outlasts any single instruction. If an agent is willing to lose your business by being straight with you, that is usually the agent worth trusting.

The best valuation is not the highest one. It is the true one, backed by evidence, from someone who will still tell you the truth when it costs them.
