The average asking price for a property in Britain is 0.1% lower than a year ago, according to the latest data from property listing site Rightmove. Despite falling on an annual basis, asking prices in Britain did rise by 0.4% on a monthly basis in September, according to Rightmove. It is the first monthly rise recorded by the property site since May, but is still lower than the typical price rise for this time of year. The rumour is that stamp duty could be replaced with an annual property tax on homes worth more than £500,000, levied at the point of sale. So far, this has not translated into lower asking prices, with no major shifts in Rightmove’s real-time data.
