Lawrence Hall of Zoopla.co.uk said: “The top end of the property market operates seemingly in isolation to the rest of the market. Wealthier buyers are relatively impervious to the economic problems affecting the rest of the market, most notably when it comes to getting a mortgage. Foreign buyers in particular have gravitated towards top-end property in London over the last few years, which has pushed up demand and prices on more expensive property as they try to secure a limited supply of top-end homes in the capital.”
