It turns out that not every blockbuster listing that sells in these parts is located on Nantucket. In fact, two of the Cape and Islands' ten most expensive sales of 2013 were actually on Cape Cod and Martha's Vineyard. They're the bottom two, of course, but on the list nonetheless.
UPDATED: It seems we left off the Cape's priciest sale (h/t @paulgroverRE), one we'd written about back in May. Thus, here are the 11 most expensive sales of 2013. Feel free to hit the tipline if there are any other additions/subtractions.
