Tax Analysis

The estimated annual property tax is $12,250 across all districts. With a homestead exemption claimed, that drops to $10,225 — saving $2,025 per year. That's $852 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.
