A year ago, estate agency guru Bob Scarff forecast that in five years time 25% of house sales would be by vendors who had opted for some form of self service.

One year in, he reckons online/hybrid agents have around 7% market share, meaning that the sector will have to grow at 4.5% in each of the next four years for the prediction to come true.

But could they run out of money first?

Scarff says this is likely. In the “no-frills sector”, he says consolidation will be this year’s word, and indeed he says there’s at least one merger rumoured.

Scarff stresses that his prediction of 12 months ago does not distinguish between pay-upfront and other models.

But he does say: “If the growth of the pay first agents slowed towards the end of last year, then it’s to do with the wider realisation that it’s only good value to pay first if you succeed in completing your sale. There’s far more awareness now of this simple fact and that’s a good thing.

“Paying first can only even begin to be good value if you complete your sale. Ergo, if you don’t, then it is clearly not.”

Scarff also revisits his categorisation of agents into four types – head in the sand; muddled thinking; foot in both camps; and two models, one brand.

Those agents with a foot in both camps, offering clear brand segmentation, “will emerge as the biggest winners”.

That was what Scarff said 12 months ago. He does not appear to have changed his mind, pointing to LSL’s backing of Yopa among other examples.

Separately, Swiss bank UBS has cut its market share forecast for Purplebricks from 15% to 12% and its target price for shares from 305p to 285p, and says that Yopa now poses a threat to Purplebricks’ growth.

It says that Purplebricks’ market share of sold subject to contracts has been around 5% since last September.

The bank’s analysts say in a note: “Given the importance of the spring market, we believe that this level of progress will be below management’s expectations, and will raise questions around the potential market share Purplebricks is able to achieve.

“Along with Purplebricks growth slowing, we can now see sustained growth from one of the challenger brands, Yopa, which has increased its market share to circa 0.5% of the market.

“Whilst this is still small relative to Purplebricks, Yopa’s strong funding position to support further advertising campaigns means this brand represents a threat.

“In addition, the growing prevalence of the ‘no sale no fee’ proposition by other online agents may disrupt further market share growth for Purplebricks.”

Yesterday, Purplebricks’ shares closed at 338p, down from 360p the day before but still significantly higher than the UBS target.
