The first two homes in this week’s roundup of Massachusetts’ most expensive home sales show how much difference a half-mile can make, even in one of the state’s most expensive neighborhoods. The two houses sit about 2,700 feet apart in Boston’s Back Bay, but their per-square-foot sale prices are separated by $880.56. The first house is almost halfway down the Exeter-Fairfield block of Commonwealth Avenue, while the latter is in Back Bay’s final block, just before Charlesgate Park and the Bowker Bridge overpass mark the transition to Kenmore Square.
