therealdeal.com – In the span of 72 hours in early May, reality-TV star and top New York City residential broker Ryan Serhant put two units under contract at 100 Avenue A in the East Village, attended a fund-raiser for cancer research at Cipriani Wall Street and traveled to the Kentucky Derby with his camera-ready fiancée, Emilia Bechrakis, whom he’s marrying next month. Oh, right, he also listed an $11.5 million townhouse on the Upper West Side.

Each of those moves was eagerly gobbled up by his 443,000 Instagram followers, who track his every move with alarming focus.
