Existing-home sales subsided for the fourth straight month in July to their slowest pace in over two years, according to the National Association of Realtors. The West was the only major region with an increase in sales last month.

Total existing-home sales, which are completed transactions that include single-family homes, townhomes, condominiums and co-ops, decreased 0.7 percent to a seasonally adjusted annual rate of 5.34 million in July from 5.38 million in June. With last month's decline, sales are now 1.5 percent below a year ago and have fallen on an annual basis for five straight months.
