Existing-home sales—a metric that includes single-family homes, townhomes, condominiums and co-ops—grew 2.9% in October, the first year-over-year increase in more than three years, to a seasonally adjusted rate of 3.96 million, up from 3.85 million one year ago. Up 3.4% from September, existing-home sales also increased in all four U.S. regions month-over-month. Year-over-year, existing-home sales rose in every region but the Northeast, where they remained the same.
