The waterfront property had been been originally listed for $14.9 million. [NYP, Corcoran]
• Whitney Houston has put her New Jersey home on the market. The 12,561-square-foot manse in Mendham Township is listed for $2.5 million; her guest cottage next door is no longer available, however. [Real Estalker, CB]
• Real estate developer Ara Hovnanian may have found a buyer for his fourth-floor apartment at 820 Fifth Avenue.

The hedge fund billionaire is expected to pay "just under" $35 million. [NYP]

• Real estate prices are plummeting and deep-pocketed buyers are hard to come by, but that hasn't changed things at 820 Fifth, the notoriously picky co-op where 89-year-old socialite Jayne Wrightsman reigns supreme. Jeff Blau, the 41-year-old president of The Related Companies, had been willing to pay a whopping $31 million for developer Ara Hovnanian's fourth-floor apartment. But Blau and his wife Lisa were told to get lost even before they had a chance to interview (and despite an intervention by the mayor). At least they're in good company: Ron Perelman, casino mogul Steve Wynn, and oil heir Fred Koch are all past rejectees. [NYO]
• Stuart Parr—furniture designer, scenester, and boyfriend of socialite Allison Sarofim—has sold his condo at 25 Fifth Avenue for $1.35 million. [Cityfile]
• Poker champion Vadim Trincher has picked up a three-bedroom, 3,073-square-foot condo on the 63rd floor of the Trump Tower for $5 million. [P6]

• Real estate titan Ara Hovnanian and his wife Rachel have quietly listed their co-op at 820 Fifth Avenue. The 6,500-square-foot apartment, which happens to be former home of Tommy Hilfiger, can be yours for $36 million via broker Serena Boardman, provided you can pass muster with a board known for having the "strongest chins, highest noses and cruelest standards." [NYO]
• Developer Louis Cappelli and his wife, actress Kylie Travis, have put their apartment at 515 Park Avenue on the market. The 6,500-square-foot, 13-room, six-bedroom spread is priced at $29.5 million. [NYO, BHS]
• New York Mortgage Trust founder Steven Schnall and his wife Sherri have put their townhouse at 2 North Moore Street back on the market. The 11,000-square-foot behemoth is now listed for $33 million. [Curbed, Real Deal]
