An estate agency is offering to sell people’s homes – and to pay them.

A flyer from Century 21 to households in Chalfont St Peter, Buckinghamshire, seems to highlight what could be a growing trend, with agents promoting online auction services to sellers who are charged nothing and may even be paid after they put their properties forward.

The agent’s flyer tells households: “We pay YOU to sell your home!”

It adds: “Sell your home for free and earn £1,000 cashback.”

The deal that is then explained is that sellers responding to Century 21 use an auction package, which will not only charge no commission but actually pay vendors.

The £1,000 cashback is payable on completion – presumably coming out of the commission that the purchaser will be charged.

The leaflet tells sellers that they can set their own timeline and reserve prices, and that “auctions are suitable for all types of properties”.

Century 21 The Chalfonts is part of Century 21 UK, which is run by large property firm SDL Group.  Century 21 UK itself is part of one the world’s largest networks of estate agents, with over 8,000 offices and 111,000 sales professionals spanning 81 countries worldwide.

The firm also has an auction business, SDL Auctions, which claims to complete over £200m worth of sales each year.

SDL, formerly known as Shepherd Direct, acquired two major auction businesses some three years ago, CP Bigwood and Graham Penny.

A spokesperson for SDL, asked to comment on its agent’s “We pay YOU to sell your home” campaign, confirmed the tie-up with its auctions arm but said that the payment offer was not unique, with other auctioneers running similar offers in conjunction with partner estate agents.

The Property Ombudsman has recently told agents that they must tell sellers that online auctions where buyers pay commission may mean that the vendor’s property does not achieve the best possible price as buyers factor in their own costs. Agents must also disclose their own commissions under a new code being promoted by the regulator, the National Trading Standards Estate and Letting Agency Team.
