How accurate are online property valuations?

Put your postcode into an online valuation tool and, within seconds, you have a figure for what your home could be worth. It is quick and convenient, but how much confidence should you put in the result?

Online valuations generally work from averages and available property data. They can give you a starting point, but they often miss the important factors that make your home worth more or less than another nearby property.

Before you plan your next move around the number on the screen, it helps to understand what is behind it.

Your home is not an average

Online valuation tools use information such as previous sale prices, property type and wider market trends to produce an estimate.

The problem is that an average cannot fully explain the differences between individual homes.

Two flats on the same street might both have two bedrooms, yet offer completely different living spaces. One could have a private garden, generous rooms and attractive period features. The other might have an awkward layout, little natural light and substantial work needed.

An online estimate may not properly account for important factors such as:

• Interior condition and the quality of any refurbishment.
• Natural light, outlook and floor level.
• Private gardens, balconies or terraces.
• Room sizes and how well the layout works.
• Lease length, service charges and ground rent.
• Building condition and planned major works.
• Noise, privacy and the position within a street.

These are details buyers consider when deciding whether to view, make an offer or move on to something else. They can make a significant difference to the price someone is willing to pay.

Why this matters in Hackney

Hackney has a huge variety of housing, often within a small area.

A period conversion, a modern apartment and an ex local authority flat might all sit within a few streets of each other. That does not mean they should be valued in the same way.

Even two apartments in the same building can differ considerably. One might have a better outlook, more usable outside space or a more practical layout.

An estimate based on averages can miss these distinctions. It can also struggle to reflect what buyers are choosing between right now.

Not ready to get an agent round?

You might only be exploring your options. Perhaps you are curious about your equity, considering a move next year or wondering whether a larger home is within reach.

You can build a rough picture of your property’s value yourself, without relying on an online valuation tool.

Search within a quarter to half a mile

Start by looking for similar properties within a quarter of a mile. Widen the search to half a mile if there are not enough useful comparisons.

Look beyond the bedroom count. Try to match the property type, approximate floor area, condition and outside space.

If you own a period conversion with a private garden, other garden conversions are likely to tell you more than apartments in a nearby new development.

Be mindful of location too. Even a short distance can change the appeal of a property, particularly when it affects access to stations, parks or popular local streets.

See where your home sits among the competition

Look at the homes a buyer could purchase instead of yours.

Does yours offer more space? Is it in better condition? Does it have a garden, a longer lease or lower service charges? Equally, are there compromises that might make another property more appealing?

Be honest. The money you have spent on your home does not automatically translate into the same increase in its value.

Ask yourself: if I were buying today, how would my home compare with these options?

Be cautious of properties that have been sitting unsold

An asking price tells you what a seller hopes to achieve. It does not tell you what a buyer will pay.

If a similar property has been advertised for months without selling, it may be overpriced. There can be other explanations, but it is not a strong benchmark simply because you like the figure.

If several comparable homes are sitting unsold at the same price, that should prompt you to question the price rather than copy it.

Recently agreed sales can provide a more useful indication of demand, although the advertised price will not necessarily be the amount agreed.

Look at sold prices from the last six months

Search for similar properties that have completed a sale within the last six months.

Where possible, find the original listing and look through the photographs and floor plan. This will help you understand whether the property was genuinely comparable to yours.

A higher sale price might make more sense once you discover that the flat had a larger garden, an extra bathroom or considerably more floor space.

Remember that sold price records can take time to appear, and the price may have been agreed several months before completion. If there are not enough recent examples, widen your search period while keeping any changes in the market in mind.

Build a realistic range

You are looking for a sensible range, rather than an exact figure.

If several relevant comparisons point towards £475,000 to £500,000, that is a stronger starting point than assuming your home is worth £525,000 because one nearby seller is asking for it.

The closer your comparisons are in size, style, location and condition, the more useful the exercise becomes.

Is an estate agent’s valuation always right?

An agent can assess the important details that an online tool may overlook, but their valuation is still an opinion of likely market value. It is not a guaranteed sale price.

The quality of the explanation matters.

An agent should be able to show you relevant comparisons, explain how your property differs and discuss the competition you would face if you launched today.

Be cautious of a particularly high figure without evidence behind it. An appealing valuation might win your instruction, but it will not help your move if buyers cannot see the same value.

Use an online estimate as a starting point

Online valuations are useful for satisfying an initial curiosity. They become less useful when an average is treated as a precise assessment of an individual home.

Doing your own research can give you a much clearer picture. Look locally, compare carefully and focus on evidence of what has sold, alongside what is currently available.

At Livco, we bring those comparisons together with an assessment of your home and the buyers it is likely to attract. We explain the reasoning behind our advice, so you understand both the suggested price and how we would approach the sale.
