Tax Analysis

The estimated annual property tax is $5,879 across all districts. With a homestead exemption claimed, that drops to $4,568 — saving $1,311 per year. That's $381 per month a buyer should budget. The assessed value increased roughly in line with the neighborhood, so a tax protest is unlikely to yield significant savings.
