A mystery buyer just scooped up one of 432 Park Avenue‘s priciest penthouses for $65.6 million — the second-highest price paid to date for a pad at the luxury tower.

The buyer of Unit 85 — identified as Parklight LLC — went into contract on the full-floor spread in April 2013, according to public records. Haroon Hamid was an “authorized” signatory on the deed.

Since closings began in late 2015, the Rafael Vinoly-designed tower, developed by Macklowe Properties and CIM Group, has racked up a spate of big-ticket sales.

Saudi retail magnate Fawaz Al Hokair reportedly closed on the building’s $87.7 million penthouse in September for over $10,600 per square foot (though he received a generous $56 million loan from CIM Group), and five units at 432 Park were among the top 10 priciest residential sales of 2016.

Unit 85, a full-floor residence with five bedrooms, a library and wood-burning fireplace, sold for $8,144 per square foot, a premium for the building. Lew Sanders, the former CEO of asset manager AllianceBernstein, forked over $60.89 million, or just under $7,600 per foot, for Unit 88 last year. And a Los Angeles-based corporation, 432 Crotona Park Avenue LLC, plunked down $59.1 million, or $7,337 per foot, for Unit 79.
