Family: Married, six kids What were your biggest takeaways from putting together One57 and Central Park Tower? Every site that I worked on — some of the more famous ones and some of the less — there’s the same rule: Most assemblage work is off-market deals, and to be successful in closing off-market deals, the seller has to understand that you’re not trying to pull a fast one, that you’re trying to work a deal that is mutually beneficial. If there’s a mistake I made somewhere, it’s that I overestimated my hand. And in those instances, I probably didn’t end up making the deal.
