Property Tax Assessment Values Across Whitethorn, Mendocino County, California
When examining property taxes in Whitethorn, California, understanding the distinction between “market value” and “assessed value” is crucial.

The assessed value is the market value minus any applicable exemptions or limits determined by local laws and offerings. The tax assessed value is the figure used to calculate your property taxes or the amount multiplied by your tax rate to get your tax bill.
Assessment notices are sent in the spring each year and typically reach your mailbox by the middle of the season. Each property owner receives an assessment notice that contains both the market value and assessed value, along with an estimate of your property tax bill.
For example, the median home price in Whitethorn is $118,698, with a median property tax bill of $1,253. That bill is below the national median property tax bill of $2,400, and the county’s tax bill range runs from $581 at the 25th percentile to $3,980 at the 90th percentile.
