Almost four in ten sellers are now choosing to use a Sale by Tender process being offered by an estate agency group – and for which they pay just £150 plus VAT as an admin fee.

The buyer pays a 2% fee plus VAT, with £2,000 as the minimum charge.

David Lench, group managing director of south-east independent Arun Estates, said: “Last year we made hundreds of sales using the method and achieved 99% of the guide price. This year, we are achieving in excess of it.”

He said that Sale by Tender is being offered through all 115 branches and all Arun Estates’ brands, including Ward & Partners, Cubitt &West, and Douglas Allen.

Lench said that all vendors are offered the option of the scheme, with current take-up being 35% to 40%.

He said: “There are vendors who do not like the idea of paying £150 upfront and who tell us they would prefer to take their chances with the normal private treaty.”

Lench said that the scheme was introduced partly as a way of dealing with a low-stock market and an instruction-getter, and partly because it adds transparency to the process.

He said: “As agents, we try to preserve our fees, but the reality is that in a low-stock market, agents do reduce them. We introduced this scheme because it is totally relevant to the marketplace we are in.

“There is limited stock and buyers are able to look at very few properties. What does an estate agent advise the vendor to do? Accept the first offer that comes in at full asking price? But then another offer comes in gazumping the first, and the original purchaser comes back with a higher offer still.

“That way, as the agent, you are almost guaranteed to get a complaint because someone will feel hard done by.

“With Sale by Tender, there is a six-week process that includes two open house days. All the tenders come in at the same time as sealed bids, and all are opened together. We encourage the vendor to come in to our offices to watch.

“It means there is complete transparency – and it works very well.

“It also fits in with the company ethos, by which we do not favour one buyer above another.

“Another benefit is that because there is a six-week programme, it slows the whole process down. One reason that vendors are nervous about putting their home on the market is that they are worried they will not be able to find anything to buy. This gives them more time.”

Lench added: “We have had some issues with it, notably Stamp Duty. We had buyers’ solicitors questioning whether by the time you added 2% back in on to a £249,000 purchase, it took the price into the next Stamp Duty level.

“However, we have now had a letter from HMRC confirming that this is not the case.”

He added that the scheme had been widely misunderstood, leading to accusations – notably by Labour shadow business secretary Stella Creasy – that the firm is double charging. However, Lench said that this was totally inaccurate.

He added that other agents could benefit from offering the scheme. He said: “It is certainly another weapon in agents’ armoury, but the emphasis must be on doing it properly.”
