Retired Cubs star Ryne Sandberg sold his 2,500-square-foot, vintage co-op unit last week in Streeterville for $580,000.

With the sale, Sandberg no longer owns any real estate in Chicago. With the exception of two years in the 1990s, he had owned Chicago-area property over a 28-year span beginning in 1985.

On March 14, Sandberg, 53, sold the three-bedroom unit, which he had listed a year earlier for $650,000. He later reduced its asking price to $624,900.

The Hall of Fame second baseman retired as a player in 1997 and became a minor-league manager in the Cubs' system from 2007 through 2010. Twice he was passed over to manage the Cubs, in 2010 and 2011. He now is the third-base coach for the Philadelphia Phillies; his offseason home is in Phoenix.

The fifth-floor unit is in a building constructed in 1920. It has 21/2 baths, hardwood floors, a formal dining room and a wood-burning fireplace. Sandberg bought the unit in 1998 for an unspecified amount and gutted it, redoing the floors, windows and kitchen.

Sandberg's listing agent, Gail Missner of Baird & Warner, said the buyers, who are not yet identified in public records, are not celebrities and are a "young couple from out of town."

Nicholas Pritzker buys $4.1M condo: Nicholas Pritzker, chief executive and chairman of Hyatt Development Corp. and a member of the Pritzker family, paid more than $4.1 million for a 5,175-square-foot condo unit in a new building in Lincoln Park.

Pritzker has divided his time between a home on Chicago's Gold Coast and California. His 7,325-square-foot contemporary-style mansion on 45 acres on Lake Michigan in Covert, Mich., is for sale at $3.9 million. He first listed it in 2010 for $4.95 million. Karen Strohl of Coldwell Banker has the listing.

On Feb. 19, Pritzker paid $4,160,500 to buy his four-bedroom condo from the building's developer, which had listed the 13th-floor unit for $4.995 million. The nine-room unit has 41/2 baths and three terraces. Tom Gorman, the agent who represented him at Baird & Warner, said he could not reach Pritzker for a comment.

R. Kelly loses mansion: Grammy-winning R&B singer R. Kelly on Monday lost his 22,000-square-foot mansion in Olympia Fields in a foreclosure sale. His lender, JPMorgan Chase, paid $950,000 to take title to the property.

The sheriff's sale was the latest in a string of financial troubles for R. Kelly, who built the gated, 16-room mansion on 3-plus acres in 1997. In the foreclosure lawsuit filed in 2011, his lender alleged Kelly owed $2.9 million on the six-bedroom mansion and had not made payments for more than a year.

Kelly listed the mansion late in 2011 in a short sale for $1.595 million. It was reduced in January to $995,000.
