Like the stock market, the roller-coaster ride in the Manhattan luxury real estate market looks like it could start up again. After a month of relative stability, with the number of contracts signed in the mid-20s, last week’s activity took a dive into the teens: Only 18 contracts were signed at $4 million and above, the lowest total since the week of February 15-21, 2016, when 13 contracts were signed. Another interesting stat: If you compare this same April week to past years, you will find that 18 is the lowest total since 2012, when 19 contracts were signed.

The No.1 contract was a townhouse at 152 West 13th Street, asking $15 million. This 5-story, 20-foot-wide red brick house was purchased for $5,850,000 in January 2014, and then gut renovated. It has 5,634 square feet including 4 bedrooms, 5 bathrooms, an elevator, a garden, and a roof deck.

The No. 2 contract was Unit 6 at 17 East 12th Street, asking $9,985,000, reduced from $14.5 million when it went on the market in June 2015. The unit has 4,514 square feet including 4 bedrooms, 5 bathrooms, and 2 fireplaces. The entertaining space spans 46 feet across 12th Street, and the ceiling height is 11 feet. It is in a new 9-unit condo that offers a concierge/doorman and deeded parking spaces for owners.
