Why Do Estate Agents Give Different House Valuations?

Welcome to our blog series on everything you wanted to know about selling a property but were too afraid to ask! OK, we're sure you're probably not afraid to ask, but there are some tricky questions out there. We come across these all the time across all areas of the property market, so here we wanted to share our advice, tips, and tricks to help you navigate the world of property.

One Agent Valued My House Higher Than the Others. Should I Trust Them?





Question from R.H, Binfield:
"We've had three agents value our house and one has come in much higher than the others. Obviously, we'd love them to be right, but should we be excited or suspicious?"

This situation is more common than you might think. When several estate agents provide valuations and one figure is noticeably higher than the others, it's natural to feel drawn towards the biggest number. After all, who wouldn't want their home to be worth more? However, the key question isn't whether the higher valuation is right or wrong. The real question is whether the figure can be properly justified."

How Estate Agents Calculate Property Valuations

A good valuation should always be supported by evidence. Ask the agent how they arrived at their figure. What comparable properties are they using? Are they basing their valuation on recent sold prices or simply on current asking prices? Are the properties genuinely similar in terms of size, condition, location, plot, and presentation?

These details matter. Sometimes an agent may reference a nearby property that achieved a higher price, but if that home was significantly larger, better presented, or located on a superior plot, it may not be a true comparison.
The most reliable valuations are built on relevant local evidence rather than optimistic assumptions.

Ambitious Valuation vs Inflated Valuation

There is an important difference between an ambitious valuation and an inflated one. An ambitious valuation can be perfectly reasonable if there is a clear strategy behind it. An agent may believe their marketing approach, buyer database, negotiation skills, or local expertise can achieve a stronger result. An inflated valuation, however, is often used to win the instruction rather than reflect realistic market conditions. Unfortunately, this can create problems later.

What Happens When a House Is Overpriced?

Launching a property at an unrealistic price can limit buyer interest from the very beginning.

The most motivated buyers are often the first people to see a new property listing. If they perceive the asking price as too high, they may dismiss it and move on to other options.

The result is often a cycle of price reductions.

Over time, a property can begin to look stale online, even if there is absolutely nothing wrong with the home itself. Buyers may start to wonder why it hasn't sold, which can weaken future interest. This is one reason why accurate pricing is so important from the outset.

Questions to Ask Before Choosing an Estate Agent

Choosing an estate agent should involve more than simply comparing valuation figures. Ask each agent what their strategy would be if the market doesn't respond as expected. How will they market the property during the first two weeks? What is their plan after the first month? How will they gather and interpret buyer feedback?
A strong agent should be able to explain:


The valuation itself is only one part of the overall strategy.

Final Thoughts

Receiving a higher valuation can be exciting, and sometimes that higher figure is justified. However, it is important not to choose an estate agent solely because they provide the most optimistic number. The best valuation is one supported by evidence, local market knowledge, and a clear marketing plan. When comparing estate agents, focus not only on what they think your property is worth, but also on how they intend to achieve the best possible outcome. A realistic strategy today is often far more valuable than an unrealistic promise that leads to price reductions later.
