Buying agent Property Vision has accused upmarket agents of shooting themselves in the foot in the wake of the election.

A blog on its site says: “Reading the papers and the gushing euphoria from the mouths of some estate agents, you would have thought that a tsunami of money was washing over the prime property markets.

“We read with interest of hundreds of millions of pounds worth of property being transacted in the wake of the surprise election result and made a mental note to check with the Land Registry in a few months time to check out what had really happened.

“The common thread in the breathless commentary was urgency to get a deal done before prices rise by 20% or more as a wave of money – put off by talk of mansion taxes and hostility to non-doms – breaks over these shores.

“Our experience is rather more prosaic. Of course the banishing of the spectre of a mansion tax is good for transactions. Layers of worry have been removed.

“However, it is our belief that the much greater long-term headwind for our market is Stamp Duty – which is a full-on transaction tax that is almost punitive. Adding a bedroom, buying an expensive pony paddock or digging a basement are so much cheaper than moving.

“The other brake on transactions is, ironically, being reinforced by the cheer-leading estate agents who have got themselves in print for their moment of glory.

“Sellers will read about the 20% ‘increase’ in the value of their property and adjust their asking prices accordingly. And it will take months – if not years – to get them back in the real world.

“It’s called shooting yourself in the foot.”
