What This Comparison Actually Tells You
Rents creates the largest separation: Walla Walla is 38.7 points lower. But goods move against the overall direction, so this is a split budget rather than a clean across-the-board winner.
Walla Walla, WA is 2.3% less expensive than Ann Arbor, MI, a meaningful but not extreme shift. The move decision turns on which budget category creates the 2.4-point overall gap.
This route crosses the national benchmark: Ann Arbor is above 100 while Walla Walla is below it. That makes the move a change of price regime, not merely a rank swap.
Comparable population context is incomplete for this pair, so no market-scale explanation is inferred from the price indexes.
For a housing-sensitive move, validate the rent gap first: HUD Fair Market Rent and the actual unit size can overturn what the blended index implies. On the BEA ratio alone, $100,000 in Ann Arbor corresponds to $97,660 in Walla Walla.
