Andre Agassi and Steffi Graf are selling their 11-bedroom mansion in Tiburon, Calif., just across the San Francisco Bay from San Francisco for $20 million, and taking a loss on the sale. The Wall Street Journal reports that hedge fund manager Stuart Peterson is paying $3 million less than Agassi paid for the mansion in 2001. (WSJ) Set on 3.5 acres, the couple’s Roundhill Estate has a 10,500-square-foot main house with a theater and a children’s wing, plus water features galore—two pools, three spas, and even a hydrotherapy waterfall. Also, the Journal reports that rocker Jon Bon Jovi has listed an apartment he owns in the Park Millennium high-rise condo tower on Manhattan’s Upper West Side for $6.95 million. The Journal claimed that Bon Jovi’s 1998 purchase price for the 28th-floor unit “couldn’t be learned,” but a quick search of public records shows that the rocker paid $1,833,000 for it. The Journal also reported that Bon Jovi’s main home is in his native New Jersey, but public records show that he actually owns a mansion on 8.37 acres in Middletown Township, N.J., along with an adjacent 6.5-acre farm.
