Here is the most extreme case – so far – of a seller planning to save money by not using a high street agent.

He owns a £15.5m house in Knightsbridge. It has six storeys, five bedrooms, a staff flat, wine cellar, gym and large garage. There are also, according to the particulars, two “additioanl [sic] WC’s”.

However, the seller – who founded a pharmaceutical company – plans to save £263,000 by putting the property with online agent Sellmyhome.

The decision was apparently taken after talking to traditional agents.

He said: “What struck me during the process of appointing an agent was the work involved to sell my house seemed disproportionate

“How can it be that selling a £15.5million property should cost 15.5 times more than selling a £1m property, when the agent’s workload is virtually identical?

“When we raised the issue with agents, there seemed to be very little wiggle room on the 1.2 to 1.7% commission.”

Of course, only in London could anyone refer to £1m houses as though they were cheap.

It’s an interesting story, told by the redoubtable Mira Bar-Hillel in the Evening Standard. Only two things, so far as we can see, are missing: a comment, complete with signs of raised blood pressure, from Ed Mead or Peter Rollings. And no sign of Russell Quirk . . . whoops, we spoke too soon. eMoov gets a mention right at the end.

There’s also something missing from the headline: ‘Tycoon saves £260,000 in estate agent fees ‘, etc,  etc. More accurate would be: ‘Tycoon hopes to save £260,000’ etc, etc. What if he manages to sell it for a mere £15m when Knight Frank could find just the buyer at his asking price of £15.5m. Then do the sums.

However, we must point out that Sellmyhome was founded by former estate agent Will Clark – who used to be with Knight Frank.

Now he does the job for £499 upfront.

Vendors conduct their own viewings and get listings on the main portals. Both Zoopla and Rightmove logos are shown. Plus Sellmyhome  is offering an October discount.

Blimey. Sarah Beeny hasn’t half missed out on this one.
