Sales of new single-family homes fell 0.7% in July from a month earlier, once again coming in well below most analyst estimates. The Commerce Department said the seasonally adjusted rate of 298,000 units last month declined from 300,000 for June, which was revised downward by 12,000. July new home sales were 6.8% higher than 279,000 a year earlier. The seasonally adjusted estimate of new homes for sale at the end of July was 165,000, representing a 6.6-month supply and near the lowest level in decades.
