Millennium Tower Penthouse Buyer: Is It This Texas Billionaire?

It's one of the great parlor games of Boston real estate: Who bought the 13,000-square-foot Millennium Tower penthouse listed for $37,500,000? It has been in contract since February.

Catherine Carlock at the Boston Business Journal thinks she has the answer: Billionaire John Grayken, and he paid $33,000,000 for it. Per Carlock, citing unnamed sources with knowledge of the deal:

Grayken, who was raised in Cohasset and now claims Irish citizenship, founded Dallas-based private equity firm Lone Star Funds in 1995. The firm, which does not have an office in Boston, says it has organized 16 private-equity funds with aggregate capital commitments of more than $65 billion since its founding.

The $33M purchase price would, of course, make the penthouse sale the most expensive home trade in Boston history (by far). Stay tuned for further details.
