The median home value is $559,100, much higher than the state's $318,300 and more than triple the national median of $173,750. Property taxes are lighter than the benchmarks: the county's median property tax rate is 0.68%, under the state rate of 0.77% and the national rate of 0.74%. High values mean the dollar amount of taxes can still be large, but the rate itself is low.
The median household income is $91,328, above both the state's $68,789 and the national $65,108, which helps explain the higher housing costs. The unemployment rate is 2.33%, below the state rate of 3.02% and the national rate of 2.87%.
