From LLNYC: An unfinished penthouse in the Four Seasons Private Residences One Dalton Street, Boston is about to hit the market for $40 million, the Wall Street Journal reports.
If the developer gets anywhere near that price for the unit, he will have broken the record for the most expensive residential sale in the city. At the moment, the most expensive sale was a $35 million penthouse that sold last year to an LLC associated with billionaire John Grayken.
