The most expensive sale of residential Vineyard real estate was completed on Tuesday in a law office in Boston. An old summer family sold 80 acres of north shore property that fronts Vineyard Sound in West Tisbury for $12 million.

The property, in proximity to Paul's Point, had been in the Albridge C. Smith family since 1943. The sellers were his two daughters: Margaret (Trika) Smith-Burke of Connecticut and Cary Hart of California. The property was put on the market early last winter.

The Flynn family has concluded the sale of more than 175 acres to The Job's Neck Trust for more than $6 million.

The property is near but not adjacent to the 800-plus acres that the Flynns recently transferred to the state to become part of the Manuel F. Correllus State Forest.
