One in three home owners would “seriously consider” using an online estate agent if selling tomorrow, says a new YouGov survey.

But while 32% would give it serious consideration, only 4% of home owners would definitely use an online agent – against the 19% who would definitely use a traditional local agent.

In the YouGov survey, 27% said that while they would almost certainly use a traditional agent they would not completely rule out using an online estate agent, and 5% would try to sell privately.

The survey was commissioned by online estate agent comparison website Selling Up, whose director Oliver Lewis said: “These findings will come as a shock for traditional estate agents who are hoping to keep their online competitors’ market share at around 5%, where we believe it currently is.

“If one-third of possible property sellers already say they would seriously consider using an online estate agent, then we could be close to the tipping point where this market really takes off and becomes fully mainstream.

“Where it will be in a few years is impossible to say, but our findings suggest that there is long-term potential for the online share of all residential property sales to end up at around 50% or even more.

“This growth would probably depend on companies like Purplebricks, easyProperty and Tepilo continuing to promote themselves heavily to attract new customers, and deliver good customer experiences for word of mouth referrals and repeat business.”

Lewis added: “In the short term, the big question is how good the online estate agents will be at converting this massive group of ‘maybes’ into customers.

“At SellingUp we believe that the online agents that will be the strongest at convincing property owners will be the ones that present a credible personal approach at the vendor’s front door combined with their price benefits online.

“Agencies with genuine property experts based in or near to the seller’s local area that have the experience to value properties accurately and handle sales progression personally will be the most persuasive, because they will reduce the perceived risk of selling without a traditional agent.”
