Metro Detroit 's industrial real estate market is making a slight comeback in leasing and construction activity, signaling a possible improvement in the area's sluggish job market. "Added industrial activity generally signals job creation," said Frank Carmone, professor emeritus at Wayne State 's Department of Marketing in the School of Business Administration . An industrial report released this week by Friedman Real Estate Group Inc. shows leasing activity in Metro Detroit climbed two percentage points to nearly 88 percent during the first six months of the year, up from 86 percent at the end of December.
