The former first family shelled out the megabucks this week for the sprawling, 6,892-square-foot abode that sits on 29.3 secluded acres facing the Edgartown Great Pond, the Vineyard Gazette reported.
The luxury digs include seven bedrooms, eight and a half baths and several stone fireplaces — as well as a two-car garage, a detached barn and a pool, according to the Gazette.
It was placed on the market in 2015, when it was listed for $22.5 million, and the price was dropped twice over the summer — once to $16.25 million in June and then to $14.85 million in July, the paper reported.
"The long and winding driveway, sprawling lawn and incredible water views make for the perfect family compound setting for generations to come," said a real estate listing for the property.
The Obamas are known to summer on Martha's Vineyard — spending part of every August there for seven out of his eight years in the Oval Office, according to the Gazette.
The only year they didn't visit was in 2012, as Obama focused on his re-election campaign.
Grousbeck and ex-wife Corinne Basler Grousbeck purchased the property for $3.1 million in 1998 from Geoffrey Gund, the Gazette reported.
