What This Comparison Actually Tells You
Walla Walla, WA and Flagstaff, AZ are a photo finish on overall price level, only 1.8 RPP points apart. A salary conversion is therefore a fine adjustment, not evidence of a fundamentally different cost regime.
Rents creates the largest separation: Flagstaff is 22.4 points higher. But goods and services move against the overall direction, so this is a split budget rather than a clean across-the-board winner.
Comparable population context is incomplete for this pair, so no market-scale explanation is inferred from the price indexes.
This route crosses the national benchmark: Flagstaff is above 100 while Walla Walla is below it. That makes the move a change of price regime, not merely a rank swap.
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 Walla Walla corresponds to $101,833 in Flagstaff.
