A new portal that bans estate agents but welcomes developers and private sellers has won the blessing of the National House-Building Council.

However, it has been slated by Rightmove.

iProperty, set up by former Swinton Insurance boss Brian Blake, launched its portal yesterday.

It wants to attract private listings while also wooing developers away from other portals.

iProperty says it offers builders a free and “credible alternative to other property websites, whose primary function is to represent estate agents”.

iProperty co-founder John Candia told Eye yesterday: “There is no question that we have launched with the backing of developers and that this would not have been forthcoming if they felt they were getting the best deals from Rightmove and Zoopla.

“I do not understand why, when server costs are going down, subscription costs are going up.”

He said he was also watching Agents’ Mutual with interest.

However, Rightmove criticised the new builders’ website, saying its message to consumers is muddled.

Candia, 38, acknowledged that the NHBC endorsement of a site that bans agents might be controversial.

He added: “Of course, NHBC members also use estate agents. I do not think they will stop using them. However, we are providing an alternative.

“Developers also realised that it is not enough simply to have a portal full only of new homes listings. There needs to be more, and so we are providing a platform for private sellers and landlords.

“It is not that I am anti agent. It is more that I am pro home owner.”

David Marchant, group head of marketing at the NHBC, is a non-executive director of iProperty.

The NHBC announced its endorsement of iProperty yesterday but without mentioning that the site is also a private sales and rental portal.

It has been set up by Candia together with Brian Blake, former owner of Swinton Insurance.

While the NHCB-backed portal has only just launched, the venture is not new: two years ago, in July 2012, Blake and Candia announced the launch of a free property app, TipC (the iPropertyCompany).

The app was described then as banning agents but open to anyone else, while Blake described himself as someone who had grown “tired of paying estate agents ranging from 1.5% in the UK to 6% in the USA”.

Yesterday, on the site, Candia said: “Home owners are sick to death of the extortionate fees charged by estate agents – particularly in a booming housing market – and increasing numbers are now looking to cut them out of the process. This is an exciting shift in the market and we are delighted to be at the forefront of this change.”

However, while its terms and conditions tell private landlords and sellers that they must only use iProperty for their own properties, it also advises them that they can still use an agent.

Under FAQ, the reply to the question “Can I use iProperty and an agent?” is: “Yes. If you feel more comfortable using a real estate agent you can still post your property for free. It really is that simple and there is absolutely no catch. Agents cannot use iProperty.”

For developers, the site is also free and offers direct contact with potential buyers.

Search results of developers’ new homes will be ranked and displayed according to their star rating, which means that properties listed by NHBC registered builders with Buildmark warranty and insurance will appear at the top of the list.

The iProperty portal, which gives addresses in Cheshire and Mallorca, plans to follow up with other launches in Spain and other English and Spanish speaking countries, and is being developed in five other languages.

A Rightmove spokesperson said yesterday evening: “Online is where most buyers and movers choose to start their research, so looking how to target the majority of that audience and spending a good proportion of your marketing budget online makes sense.

“However, while this new site seems to offer great clarity about promoting the interests of the new-build sector by being set up to mainly display new-build, it appears to have little clarity about serving up what the consumer wants.

“New portals often fail to start from the consumer perspective, and well-established consumer behaviour is to look at the widest selection of both new and resale property mixed together in one place, enabling them to compare the relative merits of each.

“If there is a fundamental flaw in not delivering what the consumer wants, then even if a portal purports to be free or low cost to list, it could actually be very poor value for money in the time, effort and brand marketing required for poor-quality leads.”
