New asking prices edged down by 0.1%, Rightmove reported this morning.

It said it is the first fall in May for five years and compares with a monthly rise in May last year of 2.1%.

However, what Rightmove calls “May” is probably not what most of us would recognise as the merry month.

Its survey of new asking prices was taken almost entirely in the jittery run-up to the election between April 12 and May 9.

Rightmove puts the average new asking price for a property coming on the market between those dates as £285,891.
