Big Ticket | Sold for $10,640,712.50

Michael Falco for The New York Times The Mark Hotel

A sponsor unit at the Mark Hotel, where a partial conversion to 42 luxury co-ops turned painful as a result of the recession - two early buyers dropped out and sued to retrieve their deposits - has sold for an exacting price, $10,640,712.50, and was the most expensive sale of the week, according to city records.

Marketed as one of three “tower suites” on the 15th floor, No. 1501, a three-bedroom, three-and-a-half-bath apartment designed by Jacques Grange and offering Central Park views from the living room, dining room, kitchen and “Grand Hotel-inspired” master bath, was originally priced at $15.75 million in 2010. The most recent asking p rice for the unfurnished 3,183-square-foot unit, which has a monthly carrying charge of $12,337, was $11.75 million.

When the 16-story Mark, designed by Schwartz & Gross and erected in 1927, closed its doors in 2007 for a grand renovation, the intention was to reinvent itself on a five-star scale and crown the hotel with 42 high-end residences on the upper floors. Although the hotel - whose amenities include the Mark Restaurant by Jean-Georges Vongerichten and a Frédéric Fekkai salon - emerged unscathed from the economic turndown, the co-op plans did not. This year all but nine unfurnished co-op units were returned to the hotel roster. With the exception of the penthouse, which is listed at $60 million, the co-ops underwent a price reduction.

The identity of the buyer of No. 1501 was shielded through a limited-liability company, EXY.

“The price reductions were calibrated to the condition of the current market,” said Kell y Mack, the president of the Corcoran Sunshine Marketing Group, which is handling the marketing and sales of the hotel residences. “The traffic has doubled since the price reduction, and we have offers on three other units.”

Big Ticket includes closed sales from the previous week, ending Wednesday.
