Housing: genuinely extreme even by Oahu standards

Cited median sale price (~$1.1M) runs meaningfully above Ewa Beach and Waipahu's own documented figures, more than 2.6x the national median.

Hawaii's statewide cost-of-living premium applies here too

Groceries, electricity, and gas all carry Hawaii's real, documented statewide cost premium, consistent with this project's Hawaii manifest research context.

A genuinely low property-tax rate offers some relief

Oahu's blended effective property-tax rate (~0.28%) is the nation's lowest, though the real dollar bill on a $1.1M home still runs meaningfully higher in absolute terms than in more affordable Oahu markets.
