Nearly half of all UK homes listed for sale over the past three years have failed to find a buyer, with new research pointing to widespread mispricing as the primary cause.
Analysis by the property portal Zoopla, based on a survey of 2,064 people who attempted to sell between 2023 and 2026, found that 44% of listings did not result in a completed sale. The findings come as separate data from Zoopla shows the average home sold for 3.5% below its asking price in the first three months of 2026 – a discount equivalent to £18,800 – as sellers were forced to cut prices to attract offers.
A market stalled by overpricing
Among those whose properties failed to sell, more than a third (34%) admitted their initial asking price was too high, despite believing it was fair at the time of listing. The pattern is reinforced by the experience of successful sellers: 53% of those who did manage to sell in the last three years said they had to reduce their asking price to secure a buyer.
The consequences of overpricing are quantifiable. Research cited in the Zoopla analysis shows that properties priced 5% above the local market average for comparable homes see a 5% reduction in the likelihood of selling. At 10% above market value, the probability of a sale drops by approximately 10%.
Richard Donnell, executive director at Zoopla, said: “Almost half of homes listed never sell. That isn’t down to luck or the market, it comes down to a few decisions, starting with understanding what your home is actually worth today.”
Why homeowners are getting the price wrong
Much of the mispricing can be traced to sellers being out of touch with current market conditions. The average homeowner selling in 2025 had been in their home for nine years, Donnell noted, meaning “many owners are out of touch with what their home may be worth.”
The survey reveals that a significant proportion of sellers are rushing the process. More than six in ten (61%) of those who failed to sell viewed other properties before obtaining a valuation of their own home. Nearly a third (32%) even put in an offer on another property before knowing how much their existing home was worth.
Financial pressures tied to the next purchase are also distorting prices. More than one in five (21%) of unsuccessful sellers said their asking price was influenced by what they needed for their next property rather than the true market value of their current home. This behaviour is particularly pronounced among younger sellers aged under 35, who are more likely to be looking to “trade up” to a larger home (44% of that age group cited this as their main reason for selling). A fifth (20%) of under-35s admitted they had overpriced a property in the last three years.
The generational divide extends to success rates. Just over half (52%) of sellers under 35 managed to sell their home in the last three years, compared with 63% of those aged 65 and over. Among older sellers, the primary motivation was downsizing (34%), a move that typically carries less financial urgency.
Broader market dynamics are adding to the pressure. The average time to sell a home in the UK has reached a record high of 205 days (nearly seven months) as of June 2025, according to property data expert TwentyEA. That figure breaks down into 80 days from instructing an estate agent to agreeing a sale, and a further 125 days from sale agreed to completion. Regional differences are significant: Scotland has the shortest average selling time at 145 days, while Inner London and the South-East see the longest delays, averaging 222 days.
Interest rates have also played a role. The average two-year fixed mortgage rate has risen to 5.42%, adding approximately £235 per month to a typical mortgage compared to rates before the Iran conflict. Higher borrowing costs have made buyers more cautious and selective, contributing to a slowdown in market momentum despite steady pricing and increased housing stock at the start of 2026.
Even energy efficiency is now a factor in pricing. Homes with an Energy Performance Certificate (EPC) rating of A or B can sell for up to 3.4% more than a D-rated property, while those with F or G ratings can sell for around 7.4% less. Zoopla uses EPC data alongside Land Registry records and official survey information to generate its online valuations.
Getting the price right: advice for sellers
Accurate valuation is the single most important step to avoid a protracted sale. Several free online tools are available: Zoopla bases its estimates on data from HM Land Registry, Registers of Scotland, official survey records, live property listings and EPCs. Rightmove’s valuation tool also draws on Land Registry and Registers of Scotland data as well as listings on its site. The Land Registry website itself shows actual sold prices in any area.
Estate agents can provide a valuation informed by local market knowledge, and many offer this service free of charge. Polly Ogden Duffy, managing director at John D Wood and Co., cautioned: “Sellers often worry about underselling, but in reality it’s far easier to oversell a property than undersell it. If a home is priced too high, buyers will simply move on – and more often than not, it will end up needing a reduction later.”
Sellers should also pay close attention to buyer signals. If viewings are not converting to offers, it may indicate overpricing, poor-quality listing photographs, or a weak first impression from the property itself. Mark Manning, group managing director of Northern Estate Agencies Group, said: “Think carefully about how your property is presented both online and at the kerb – first impressions really do still matter – and be prepared to adapt your strategy if your initial approach hasn’t landed. The sellers who struggle are almost always the ones who simply wait and hope something changes.”
