Former WBBM-Ch. 2 sports director Mark Malone, who played quarterback for a decade in the NFL, has sold his two-bedroom, 2,200-square-foot condo in a Greektown loft building for $557,500.

Malone, 54, played for the Pittsburgh Steelers for eight seasons in the 1980s. After his playing career ended, he went into broadcasting, working in Pittsburgh and on ESPN. He joined CBS-owned WBBM-Ch. 2 in 2004 and was sports director and lead sports anchor until the station declined to renew his contract in 2008.

Malone holds two broadcasting jobs outside the Chicago area. He long has been a booth analyst and sideline reporter for DialGlobal. Last month, he and fellow former NFL quarterback Donovan McNabb were tapped to co-host a new afternoon talk show on NBC Sports Radio.

As a result, Malone, who lives in Scottsdale, Ariz., has cut his remaining real estate tie to Chicago.

On May 6, he sold his condo, which he initially listed for $574,900. Features in the corner unit include two baths, 180-degree views, a 35-foot balcony, 14-foot ceilings, hardwood floors, a five-burner cooktop, window treatments and new granite countertops.

"The unit went really fast, selling in just five days," said listing agent Jacqueline Bohn of Century 21 Lullo. "The downtown market is really hot."

Malone bought the unit in 2007 for $700,000.

Former WBBM-Ch. 2 news anchor Linda MacLennan listed her six-bedroom, 6,000-square-foot, stone manor-style mansion in Wilmette's Indian Hill Estates area for $2.9 million on May 20.

MacLennan, 57, left the station in 2003, runs a photography business and is serving as interim executive director for the nonprofit Wilmette Theatre. She paid $2.7 million for the mansion in 2005.

Features include 6 1/2 baths, a first-floor library, a large finished lower level, five en suite bedrooms, a large mudroom, a master suite with a fireplace and a Juliet balcony, an attached three-car garage and an outdoor fireplace.

Lyn Flannery of Prudential Rubloff has the listing.

WGN Radio's Jimmy de Castro buys Northfield house

New WGN-AM 720 President and General Manager Jimmy de Castro, who for more than a year has tried to sell his lakefront mansion in Winnetka for more than $4 million, recently paid $1.43 million for a 3,323-square-foot house in Northfield.

Last week, de Castro, who ran WLUP-FM during its heyday in the 1980s, was named the boss of WGN-AM 720, which, like the Chicago Tribune, is owned by Tribune Co.

De Castro bought his four-bedroom mansion along Lake Michigan in Winnetka for $4.5 million in 2005. In March 2012, de Castro listed the 4,260-square-foot home for $4.5 million, and he cut the asking price to $4.15 million in September.

De Castro and his wife recently bought the five-bedroom, Cape Cod-style house on 1 acre in Northfield. Built in 1957, the nine-room house has 3 1/2 baths, a bay window in the living room, custom built-ins, a newer kitchen with granite countertops, wood cabinets and top-of-the-line appliances, and a first-floor master suite. Outside are a landscaped yard and pool.

De Castro bought the house in a private transaction from Kathleen Wirtz, who was married to Chicago Blackhawks Chairman Rocky Wirtz until their divorce in 2003.

In an interview, de Castro said his latest real estate moves are driven by lifestyle changes and a desire to downsize. De Castro said he recently sold properties in Nantucket, Mass., Carmel, Calif., and Colorado, and has his eye on "estate planning" and on "making our green footprint smaller."

"We're moving 1 mile, and we're redoing the new house so it will have all our bedrooms on one level," he said.
