Aon Center, the third-tallest building in Chicago, has sold for $712 million, reports Crain's Chicago Business.
A firm called 601W Cos., led by New York real estate investor Mark Karasick, struck the deal to buy the 83-story tower located next to the two-tower Prudential Plaza, which it already owns. The tower was sold by Piedmont Office Realty Office Trust, which purchased the building in 2003 for $462.5 million.
The tower attracted bids from a large number of investors across the country and around the world, driving up the value, says Chicago Business. The building is selling for $260 per square foot--a significantly higher price than the $650 million range estimated when Piedmont introduced its sale earlier this year.
