Why county rates vary so much

Property tax is set locally, not by the state, so the rate depends on the county, city, school district, and special districts where a home sits, and on how those local budgets compare to local home values. A county with low home values can still have a high effective rate if its local budgets are large, and a wealthy county can have a low effective rate. The effective rate shown here is the median tax bill divided by the median home value, which is the standard way to compare places; your own bill depends on your assessment and any exemptions.
