The Pierre: Another Year On Top; Another Year Unsold

Inside Martin Zweig’s penthouse.

Once again, Forbes’ Sara Clemence researches extensively to provide a luxury real-estate list. Previous pieces tracked the most expensive zip codes or rentals; this latest one tackles the priciest penthouses in several U.S. cities.

Hedge-funder Martin Zweig’s $70 million penthouse tops the list once again here in Manhattan. However, it’s unfortunate that 16-room spread at the Pierre gets the 2006 prize, considering that it hasn’t budged since October 2004. Not even a price cut to entice wealthy buyers.

So is Mr. Zwieg serious about selling the 11,000-square-foot apartment, or does it remain on the market solely to take the top spot on real estate “best of” lists?
