Assessed Value vs. Market Value
These two numbers describe the same house but mean very different things.
Assessed value
Assessed value is the figure a county assessor assigns to a property to calculate property tax. It's often a fraction of true market value and updates on the county's schedule, not with the market.
Market value
Market value is what a property would actually sell for today — driven by buyers, comparable sales, and condition. The last sold price in the dataset is the best public record of realized market value.
Why they differ
Assessment methods, caps, and reassessment lag mean assessed value can trail market value by years. For market signal, use recent sale prices; for tax context, use the assessment.
Frequently asked
Is assessed value the same as market value?
No. Assessed value is set by the county for tax purposes and is often below market value, which is what a property would sell for today.
Where do I find a property's sale price?
The dataset records each property's last sold price and date, plus full price history in the Parquet files.
