The first property in this week’s roundup of Massachusetts’ most expensive home sales hadn’t been on the market in 30 years when it sold last month, according to the listing. The four-building compound backs onto over 100 acres of conservation land and takes its location to heart. The front garden is planted with perennials, the property includes deer-proofed vegetable and flower gardens – and the whole property is certified organic, according to the listing.
