BRITISH commercial property values in November made their biggest monthly gain since records began nine years ago, rising 2.7 per cent and marking the fifth consecutive monthly increase, the latest report from consultants CB Richard Ellis’ (CBRE) Monthly Index found.<br /><br />Values have been rising since July when they were down 44 per cent from the last peak reached in mid-2007. The growth in November was led by retail warehouses and shopping centres, up four per cent and 3.9 per cent respectively, boosting total returns -- comprising rental income and capital growth -- to a record 3.4 per cent, CBRE said. <br /><br />“The strength and depth of current investor demand seems destined to lead to a continuation of the very strong returns seen in recent months into next year,” David Wylie, head of economics and forecasting at CBRE, said. <br /><br />“However the prospect of more significant increases in supply coming through, and the generally weak rental growth outlook, may act as a brake on the strength of the recent recovery,” he said. <br /><br />Average rental values continued to fall, down 0.3 per cent in November.
