Prosperity Realty.

The approximately 60,000 square-foot building at 135 William Street has been sold by Prosperity Realty, a holding company for Shanghai Commercial Bank, to a syndication that is a client of Edmond Li and Samuel Lee of Helmsley-Spear.

"They will convert the vacant floors to residential, and the commercial tenants leave they will convert the floors," said Li. Some commercial tenants will also have to be moved within the building. "They will have to do it piecemeal based on the fact that some of the leases run five years or six years out," Li says.

Ralph Krueger of The Corcoran Group was the exclusive sales agent and is glad the deal is done because he was giving tours to "every bottom fisher on Wall Street."

"I was climbing up and down 16 stories, and up on the roof and into the basement through 100 degree weather last July," he recalls. Sure, there are elevators, he agreed, "but when guys want to see every floor, and some want to see the roof, and a lot want to see the basement, it doesn't make sense to use the elevator."

Li and Lee also represented the Dutch Reformed Church in its sale of 102 Fulton, which is now in contract with a closing expected in the beginning of November. That's a 50 x 100 loft building that will also be converted by a locals.
