Talk about a comeback! Twenty-eight contracts were signed last week at $4 million and above, a more than 50% rise over the previous week’s total. Hang on tight—the roller- coaster ride that we’ve been experiencing in the Manhattan luxury real estate market looks like it ain’t over yet.

For the second time in 3 weeks, the No.1 slot went to a unit at 432 Park Avenue. Apartment 66B, asking $32.5 million, has 4,019 square feet including 3 bedrooms and 4.5 bathrooms, with views of the city and Central Park. The unit features 12.5-foot ceilings and windows that measure 10 x10 feet. This new condo is 96 stories high with 142 units, a concrete-and- glass edifice designed by Rafael Vinoly that is 1,396 feet tall and can be seen from almost anywhere in the 5 boroughs. Amenities include a fitness center, a 75-foot pool, private dining, parking, a garden, and a children’s playroom.

The No. 2 was Apartment 2/3D at 740 Park Avenue, asking $22.5 million, reduced from $29.5 million when it went on the market in September 2014. Designed by Alan Wanzenberg, this 15-room duplex co-op has 4 bedrooms, 4.5 bathrooms, and 3 maid’s rooms, and faces south on 71st Street. The entertaining space is downstairs, and has a 13-foot terrace off a 37-foot living room. 740 Park is one of the all-time status buildings, and was chronicled in a book by Michael Gross. It was the childhood residence of Jacqueline Kennedy Onassis, and current residents include David Koch, Ron Lauder, Vera Wang, and Blackstone CEO Stephen Schwarzman.
