Radiologist Kenneth Heithoff and his wife Karen sold a unit in Fisher Island’s Bayview condo development for $8.1 million.
The Heithoffs sold the 6,500-square-foot condo at 4911 Fisher Island Drive for $1,246 per square foot, records show. MB Fisher, which lists Richard Sobel of MB US Real Estate Holdings at its manager, bought the condo.
Kenneth Heithoff was formerly a radiologist and entrepreneur who started St. Louis Park, Minnesota-based Center for Diagnostic Imaging, a medical imaging center. He sold the company to Onex Corp. for $160 million in 2004, according to the Minneapolis/St. Paul Business Journal.
Jill Eber of Coldwell Banker Residential Real Estate represented the seller. The buyer was represented by Larry Rivero of Rivero Real Estate.
The home features a 2,000-square-foot wraparound terrace, according to Realtor.com.
The Heithoffs bought the condo for $3.04 million in 1997, records show. Bayview is a collection of buildings on Fisher Island’s northwestern side with units ranging from 1,950 square feet to 9,570 square feet.
With limited options for new development, condo units on the island command high prices. PDS Development, led by Heinrich von Hanau, recently completed the 50-unit Palazzo Della Luna on the Island. A unit at the luxury condo development sold last week for $17 million.
