San Diego vs Seattle: Cost of Living Comparison
San Diego and Seattle are West Coast tech hubs with premium costs of living, but their economic engines and lifestyles differ markedly. Seattle's Amazon-and-Microsoft economy comes with no state income tax, offsetting its high housing costs. San Diego's military presence, biotech industry, and tourism base spread across a sunnier, more spread-out metro. Housing costs are comparable in desirable neighborhoods, but Seattle's lack of income tax gives it a meaningful take-home pay advantage over California.
