Real talk: the #1 spot goes to Washington, and the breakdown explains why. And from what we can tell, renters here pay $2,406/month — costing renters $6,132 more per year compared to the national average. Meanwhile, Utilities is the standout at index 115, keeping costs manageable. The weak spot? Housing at 162. A 27% rent-to-income ratio keeps most households inside the safe zone.
If you only look at rent, it's perfect. Zoom out and it's complicated. In Washington, the housing index sits at 162 — above average and worth factoring in (that's pre-tax, of course).
