DETROIT, MI - October marked the eighth straight month that the median selling price in Metro Detroit rose by double digits annually.

According to Realcomp, the Farmington Hills-based Multiple Listing Service for southeast Michigan, the median selling price for homes in Metro Detroit was up 41.9 percent year-over-year last month to $127,000.

Realcomp defines Metro Detroit as Wayne, Oakland, Livingston and Macomb counties.

While prices again climbed at a impressive clip, the number of total sales by units was far more modest in metro Detroit, as the 4,985 homes sold there last month represented a rise of just 2.0 percent over October 2012.
