How we verify facts

What do Mercer County property taxes and assessments look like?

Figures from public records and the Census, each with its source. They describe the county's homes as a group, not the value of any one home.

What do homeowners in Mercer County pay in property tax?

The median owner-occupied home in Mercer County was worth $377,700, and the median property tax its owners paid was $8,909 a year, according to the Census Bureau's American Community Survey.

Median home value: $377,700; Margin of error ±$6,110.
Median property tax paid per year: $8,909; Margin of error ±$148.
Median tax as a share of median value: 2.36%; A ratio of two medians, not a tax rate. Your own bill depends on your assessment and local levies.
Owner-occupied homes: 89,569; Margin of error ±1,662.

These are survey estimates of what owners reported about their own homes. They are not assessed values, not tax rates, and not an opinion of what any home is worth.

They cannot tell you whether your own assessment is fair. That takes a comparison with similar homes, which we offer only in counties we have researched.
