CHICAGO—Cushman & Wakefield officials say they have begun marketing a three-building retail asset on N. Michigan Ave. that could bring in more than $300 million, which would make it one of the city's most lucrative retail sales ever.

The company will market the properties, located at 663, 669, and 673 N. Michigan Ave. and currently home to Nike, Cole Haan and Garmin, as “669 Mag Mile.” The offering consists of two land parcels totaling 23,598 square feet at the northeast corner of Michigan Ave. and Erie St. C&W officials add that the three buildings, which span about 148,000 gross square feet, have "advantageous zoning and no historic landmark restrictions."

“669 Mag Mile is a coveted collection of real estate at the center of a world class urban retail destination,” said Michael Marks, senior director of retail investment advisors for the firm in Chicago, in a prepared statement. He was not available for further comment by press time. “This is a hyper-core asset with compelling value-add features and future development rights. The Chicago market has not seen this blend of opportunity along one its high streets in quite some time. These attributes will attract investors from around the globe.”
