Eco Analysis - US Housing Activity: Multifamily mayhem (B. Jones) ■ Powered by a surge in multifamily activity, housing starts jumped to 17-month high The number of new housing units started jumped by 15.0% to a seasonally adjusted annual rate of 658,000 in September, following upward-revised tallies of 615,000 in July and 572,000 in August. The reported figure exceeded the consensus expectation (590,000) by a country mile and represented the strongest activity since April 2010 (687,000). Reflecting solid demand for rental dwellings, multifamily starts soared by 51.3% to 233,000, accounting for all but a fraction of last month's rise. Single-family starts, climbed by a comparatively modest 1.7% to 425,000, essentially matching the July-August average.
