What this benchmark means
Median real estate taxes paid ÷ median owner-occupied home value, ACS 2020–2024 — a ratio of two medians, not a statutory rate, not the median of individual bills and not your property's rate. Exemptions people already claim are reflected in the survey; your bill depends on taxable value, local districts, exemptions and reassessment after a sale.

All 39How this benchmark was computed
Median real estate taxes paid by owner-occupied households in Chelan County ($3,503) divided by the median value of those homes ($490,100), both from the Census Bureau's American Community Survey 2020–2024 5-year estimates. It is a ratio of two medians — a reasonable area benchmark, not the assessor's mill rate and not any one household's rate. Newly purchased homes are often reassessed to sale price, so a buyer's first bill can run above it. Data & method
