Twenty Two Liberty

Vertex founder Joshua Boger was instrumental in the company’s decision to move from Cambridge to a brand-new billion-dollar headquarters on Boston’s Fan Pier. Now he’s bought two condos next door at the Twenty Two Liberty tower for $9.4 million.

Michael A. Bass, a Boston real estate attorney, did Boger one better: he’s acquired three units in the 14-story complex for a combined $16 million.

Boger and Bass are among the buyers listed in the initial round of closings at Twenty Two Liberty. From Nov. 18 through Dec. 4, 63 condos have sold for a total of more than $146 million, according to Suffolk County Registry of Deeds filings and data compiled by The Warren Group, publisher of Banker & Tradesman.

Developed by Boston-based Fallon Co., the 109-unit complex was sold out six months ahead of its late November opening, reflecting its front-runner status as the first luxury condo tower completed in the Seaport since the recession.

Bass, who specializes in estate planning and complex real estate transactions, declined comment. It was not clear whether he bought the condos for himself or on behalf of a wealthy client who will combine them into a larger spread.

“When you have a sale like that, you do it preconstruction and you complete the requests to modify (the layout) prior to sale,” a real estate source said.

Tech entrepreneur Paul English, who bought a penthouse unit for $6.8 million, said he’s heard the rumors that Patriots owner Robert Kraft will be a neighbor. Patriots spokesman Stacey James declined to comment, and Fallon Co. would not discuss buyers.

Corporate executives, money managers and attorneys are well-represented in the first round of buyers. Despite chatter about the influence of foreign investors on the high-end condo market, many of the buyers have local connections.

Bass, managing partner at Boston-based Bass, Doherty & Finks P.C., bought two penthouse units for $8.3 million and $3 million and a third condo for $5.1 million in all-cash transactions.

Vertex’s Boger closed $6.9 million and $2.5 million condos on Nov. 19.

Vertex executives first started to consider the Fan Pier as the new headquarters for the pharmaceutical giant through a connection to another Fallon property, the One Marina Park Drive office tower. Developer Joseph Fallon gave startup accelerator MassChallenge free office space there during the recession at the urging of the late Boston Mayor Thomas Menino as part of Menino’s efforts to transform the Seaport into the city’s new Innovation District.

A Vertex executive took a hot air balloon tour of the site after participating in a MassChallenge biotech forum and urged Borger and other executives to consider the site, Fallon told Banker & Tradesman earlier this year.

“We’re finding a lot of local buyers,” Fallon said. “For many of the buyers this will be a second home for them. They love the convenience.”

Fallon sold the Vertex headquarters to Newton-based Senior Properties Housing Trust in 2014 for $1.1 billion. Ground was broken last month on the 14-story 50 Liberty tower, which will contain 120 condos on the site directly to the east of Twenty Two Liberty. Construction continues on the 17-story, 516,000-square-foot 100 Northern Ave. office building that will become the new home of law firm Goodwin Procter LLC next year in a relocation from the Financial District.
