Here are the 10 biggest loans in Chicago in the past year

Chicago’s Downtown office towers dominate the skyline and they also accounted for most of the top 10 commercial mortgages that lenders provided over the past year, according to a new analysis by The Real Deal.

In the wake of Blackstone Group’s record $1.3 billion refinance on the Willis Tower this week, TRD tallied the biggest loans in Chicago from March 1, 2017 to February, 28, 2018.

Of the total $3.7 billion borrowed, KSB Realty led the way with its $1.01 billion refinancing on the office tower at 500 West Madison Street above the Ogilvie Transportation Center in the West Loop. Other big loans went to finance office buildings at 150 North Riverside Plaza, 181 West Madison Street and 1 South Dearborn Street.

The big borrowers also had their hands in other sectors of the real estate market, including high-profile projects like the Old Main Post Office overhaul, the ongoing renovations at Wrigley Field, and the construction of a 60-story residential tower on Wolf Point.

See the entire list below. And keep an eye out for more signature rankings from TRD.
