Boston proves it with a cost index of 205 — which, honestly, is lower than you'd expect here — , the lowest in Massachusetts, and we've ranked all 4 contenders to help you find the best deal in an expensive landscape.
Rent data is sourced from Zillow's Observed Rent Index (ZORI), which tracks the median rent across all active listings — not just new leases. This gives a more representative and stable signal than asking prices alone. Boston: $3,510/mo, Cambridge: $3,355/mo, Lowell: $2,262/mo.
The #1 spot goes to Boston, and the breakdown explains why. Renters here pay $3,510/month — costing renters $19,380 more per year compared to the national average. Meanwhile, Healthcare is the standout at index 121, keeping costs manageable. The weak spot? Housing at 205. The 44% rent-to-income ratio is a pressure point — for median earners, housing takes more than recommended.
Here's where the story takes a turn: 79-point cost gap between #1 and #4. Boston (index 205) and Worcester (index 126) sit 79 points apart on the cost index — proof that Massachusetts is far from monolithic in affordability. One to watch.
