With record-high rents and a development pipeline that will add nearly 9,000 apartments to the downtown market by the end of 2017, the sky seems to be the limit for Chicago-area multifamily. How long will the streak continue? Chicago’s leading developers, including Taylor Johnson clients Fifield Cos., M&R Development,  Evergreen Real Estate Group and Ascend Real Estate Group, will talk trends and predictions at Bisnow’s 7th Annual Multifamily event, kicking off at 7 a.m. tomorrow at the JW Marriott.
