Tax Analysis

The estimated annual property tax is $11,148 across all districts. With a homestead exemption claimed, that drops to $9,345 — saving $1,803 per year. That's $779 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.
