BUZZ-UK property: trouble in Earls Court

** UK property stocks fall on Tuesday, led by Capital & Counties after the London-focused developer wrote down the value of its Earls Court site

** Cuts valuation of its Earls Court site to £1.2 bln from £1.4 bln, a fall of 14 pct

** Poor sales figures also a cause for concern

** Co says it has sold just 4 units in its 7,500 unit development since the last trading update in May, all after the EU referendum result

** Previous update said 9 had been sold in the quarter from Feb 24, sparking concern of a slowdown in London new-build property

** Signs capital appreciation at the site has also stalled: in May, Capco said phase 2 prices were 5 pct ahead of phase 1; July update says prices now 4 pct ahead

** Rest of the fallers in the property sector led by high-end estate agent Foxtons, housebuilders all down 1-2 pct
