|---|---|---|---|
| State income tax (WA) | Zero | $0 (Idaho) | Income tax is a draw — both effectively zero for most retirees |
| Property tax — $700K home | $5,600–$8,400/yr (King County ~0.8–1.2%) | ~$4,370/yr (Ada Co., $700K after homestead) | King County rates vary significantly by city; Bellevue/Redmond higher |
| Home equity (Seattle area) | $400K–$1M+ (Eastside often higher) | — | Seattle buyers converting equity bank meaningful capital |
| Climate difference | Cool, rainy, overcast Oct–May | Dry, 240 sunny days, real winters | WA buyers often welcome Boise's sunshine and dry climate |
Seattle buyers are the second-largest feeder group in the Boise market after California. The financial case is less dramatic than California — Washington has no income tax, so there is no income tax arbitrage. The primary drivers are property tax savings, equity conversion, and climate.
King County property tax on a $700,000–$900,000 Eastside home runs $5,600–$10,800 per year depending on city. Ada County on the same value runs $4,370 after the homestead exemption. The property tax savings are real but smaller than the CA comparison. The equity conversion is real — $275,000 banked from the Bellevue example above — but smaller than Bay Area moves.
The climate argument is the strongest driver for many Seattle buyers. Boise averages 240 sunny days per year. Seattle averages approximately 70 sunny days. The cloud cover and rain of a Seattle winter is the primary lifestyle complaint among Pacific Northwest retirees. Boise's dry high desert climate and 4 full seasons (including a real summer) is genuinely different.
