NYC’s Socony-Mobil Tower Said on Market for $900 Million

The midtown Manhattan office tower known as the Socony-Mobil Building is on the market with an asking price of about $900 million, a person with knowledge of the seller’s plans said.

Hiro Real Estate Co., a Japanese investment firm, is seeking to sell the long-term leasehold, which would give the buyer rights to control the 1.7 million-square-foot (158,000-square-meter) landmark at 150 E. 42nd St., said the person, who asked not to be named because the marketing effort is private.
