Hard sell

Jennifer Gould Keil

It looks like Bruce Willis and stunning wife Emma Heming think their Upper West Side condo is expendable. Willis is even willing to sell it at a loss.

The “Die Hard” star has just put his three-bedroom, three-bathroom condo at Trump Place at 220 Riverside Blvd. on the market for $3.95 million. He bought the 2,300-square-foot apartment in 2007 for $4.26 million. The 20th-floor unit has gorgeous views of the Hudson River and the George Washington Bridge.

We last spotted Willis and Heming on an apartment hunt almost two years ago with broker Wendy Maitland (who’s now with Town Residential). The pair — hot off a kinky, S&M-style photo shoot for W magazine — checked out high-priced pads at 15 Central Park West and Trump International, at 1 Central Park West.

BRUCE IS LOOSE: Willis has listed his Trump Place condo for $3.95 milliion.

Harlan haven

Best-selling mystery author Harlan Coben — who, as we first reported, is buying in the Dakota — has put his one-bedroom pied-a-terre on West 67th Street on the market.

He’s asking $745,000 for the 700-square-foot unit at the Atelier co-op building. The unit has 11-foot, 4-inch ceilings, a handcrafted dark wood and brass bar and a bathroom with a porthole. The 17-foot-wide living room has a beamed ceiling and a leaded window. Listing broker Jeffrey Rowe of Stribling & Associates could not be reached for comment.

Coben, whose latest novel, “Live Wire,” was just released, still has a house in Ridgewood, NJ.

And we hear that the author has passed the swanky Dakota’s co-op board. The deal for his 1,600-square-foot, two-bedroom co-op there, which had a $2.69 million asking price, should be closing soon.

‘Wash’ up

The top five floors of the 471 Washington St. new development in TriBeCa have gone into contract for around $20 million. We hear that the undisclosed buyer, who is getting a four-story penthouse with a private pool plus the full-floor apartment below it, is a Wall Street financier. His identity should be revealed next fall when the negotiations are aired on Bravo’s “Million Dollar Listing.”

Altogether, the buyer is getting more than 7,100 square feet and 11-plus-foot ceilings inside and more than 4,300 square feet outside with five terraces and an outdoor kitchen.

Broker Fredrik Eklund of Prudential Douglas Elliman had no comment.

Huffington hunt

Big-bucks blog queen Arianna Huffington, who recently sold the Huffington Post to AOL for $315 million, looks like she’s ready to put some of her Internet money into a brick-and-mortar apartment rental.

Huffington was spotted checking out a three-bedroom, 3½-bathroom, $25,000-a-month unit at 40 Mercer St. — the hip Andre Balazs/Jean Nouvel building in SoHo. The 2,370-square-foot residence recently had its price slashed from $28,000. The luxury building features a pool and underground parking.

Corcoran Group broker Meris Blumstein, who was spotted with Huffington, declined to comment.

‘Post’ exclusive

A Bernardsville, NJ, mansion that was designed by and served as the summer home of famed architect George Browne Post is on the market for $10.8 million.

The seven-bedroom, 7½-bathroom residence comes with more than 70 acres of land on Claremont Road. Outside, there’s a stone courtyard. Inside, glass doors open to a marble-floored center hall and a sweeping staircase. High ceilings, detailed moldings and fireplaces abound.

Broker Ashley Christus of Turpin Real Estate has the listing.

We hear . . .

That’s HGTV’s “Selling New York” traveled to Boca Raton, Fla., to film Venus Williams, brokers Michele Kleier and daughters Sabrina and Samantha and other party-goers at One Thousand Ocean’s $15 million penthouse. The Kleiers are representing the project in New York. Spies also report that music mogul Tommy Mottola and his wife, Thalia — pregnant with their second child — were at the building several times to discuss the potential purchase of two combined units for around $9 million, but the deal fell through. . . . That real estate honcho Larry Silverstein and Gimme Shelter regular Alec Baldwin (whose quest for the perfect apartment we are perpetually chronicling) have just been elected to the New York Philharmonic board of directors.
