The second home in this week’s roundup of Massachusetts’ most expensive home sales is a case study in how to make sure new-construction luxury condominium keeps its value. The penthouse at The Residences at Charles Square, next to Harvard Square, comes with skyline views, yes, but tasteful renovations and an up-to-date kitchen makes it feel like a unit in one of Boston’s new towers.
