Property companies and listed REITs in particular should cut their gearing and buy back their stock, according to John Lutzius, Managing Director of Green Street Advisors. Speaking at the annual EPRA and Nabarro Insight event in London on Tuesday, Lutzius fuelled the debate by concluding that leverage across the industry was still too high and that listed REITS especially had been 'too aggressive on development'. He recommended a level of around 30% and even as low as 20%.
