Zoopla has warned of the impact of estate agents over-valuing properties.

Research by the portal claims that ‘over-priced’ homes take 58 days longer to sell than those that are sold for closer to asking price, rising to 60 days in London.

The research, which analysed initial asking prices and cross-referenced them with sold prices from the Land Registry database across 12 months, says over-priced properties end up selling for £12,000 less than their initial valuation.

Homes that were not discounted in the final sale price were described as fairly priced and those that were discounted in the final transaction were deemed to have been initially over-priced.

A Zoopla spokesperson said: “Where homes have been subject to a discount, they are categorised as having been over-valued initially. In other words, the research has been underpinned by an assumption that the transaction value represents the true market value.”

The analysis covered the period between June 1, 2018, to May 31, 2019, and found that the median asking price for over-priced homes – those that end up selling below asking price – was £235,000, while the eventual sold price at the Land Registry was £223,000.

In contrast, homes that were deemed to be priced fairly were listed at £199,995 and sold for £200,000.

It took 77 days for homes that were eventually discounted to go under offer, and 19 days for those that weren’t.

The research found that homes in Salford, Driffield and Dronfield, on average, each achieved 100% of the initial asking price, which Zoopla said suggests agents based in these towns are particularly skilled in managing sellers’ expectations and assessing the state of the local market.

The success of sellers in these towns compares to the English and Welsh average of homes achieving 96.3% of asking price.

Charlie Bryant, managing director of Zoopla, said: “Our research highlights the importance of accurate pricing and reveals the areas where there is the healthiest alignment between a seller’s expectations and what a buyer is willing to pay for a property.

“When a home is valued too ambitiously at the start, or simply overpriced, the sales process can be derailed. Homes can languish on the market for much longer than they should and the vendor loses control of the sale, often leading to price reductions.

“Agents in Salford, Driffield and Dronfield stood out in our report in aligning their vendor expectations with the realities of the market, and what a potential buyer is willing to pay for that particular house, in that particular location.

“The English and Welsh average sold price, which amounts to 96.3% of the asking price, indicates a market realism, and moreover a market that is transacting good values, despite wider macro-economic and political concerns.”
