The American housing market remained in the doldrums last month with house sales at their lowest number for four years. Sales fell 0.3 percent to an annualized 5.99 million units in May, the lowest figure since June 2003. There was also bad news from Lennar, America’s biggest house builder, which announced a $244.2 million loss for the second quarter of 2007. Lennar’s average sales price fell by 7.5 per cent to $298,000.
