Property tax bills in Castro County are based on the assessed value of a home and the local tax rates applied to that value. When a property’s market value rises, the assessed value can increase too, which often leads to a higher bill. Local taxing entities use that assessed value to calculate what each homeowner owes, so two homes with different values can face very different tax bills.
In Castro County, the median home price is $61,610, and the median tax bill varies widely across homes. The 25th percentile tax bill is $424, while the 75th percentile is $1,317 and the 90th percentile reaches $1,829. That range shows how property taxes can affect homeowners differently depending on home value and location.
For homeowners, this means a higher assessed value can translate into a larger annual expense, while a lower value may keep the bill more manageable.
