If you don't mind commuting a bit, Franklin MA might not be that bad of a place to look either. It's about 30 minutes from both Marlborough and Norwood. It has 2 commuter rail stops (Forge Park and Franklin) on the same line as Norwood. BJs, Shaws, and Stop & Shop are in Franklin, while Market Basket, Walmart, Whole Foods, and Home Depot are in neighboring Bellingham, and the Wrentham Outlets are quite close by. Walkability is a bit iffy, especially in West Central Franklin due to 140 being a 4 lane expressway between the Bellingham border and 495.
