Deep Dive: Each State
Arizona (AZ)
Tax reality

Top cities (4 tracked)
Top drawbacks
- ✕Summer heat is genuinely extreme. 110°F+ days are common June-September, and 2023 saw Phoenix hit 119°F. Outdoor life basically stops — you exercise at 5am or not at all.
- ✕Electricity bills in summer are shocking — AC running 24/7 can push monthly bills to $400-$600 in detached homes. New builds with better insulation help.
- ✕Water security is a long-term question mark. Colorado River allocations are being reduced, and the state has groundwater commitments exceeding sustainable withdrawal. Urban water supply is fine now; long-term planning is uncertain.
Washington (WA)
Tax reality
Washington has no state income tax on W-2 wages. The state collects revenue through a 6.5% state sales tax (local rates push it to 9-10% in most metros) and a Business & Occupation (B&O) gross receipts tax that affects self-employed workers. A 7% capital gains tax (passed 2021) applies only to gains over $250K on investments — so most people never hit it.

Top drawbacks
- ✕Cloud cover from October through April is serious — many newcomers experience genuine seasonal affective disorder (SAD). If you've never lived somewhere with low winter sunlight, test with a 2-week November visit before committing.
- ✕Home prices in Seattle proper have stayed high — $750K-$850K median for a modest SFH in decent neighborhoods. Bellevue and eastside tech suburbs run higher.
- ✕Sales tax 9-10% stings. Every purchase is noticeably more expensive than in no-sales-tax states like Oregon or Montana.
