Tax Analysis

The estimated annual property tax is $10,339 across all districts. With a homestead exemption claimed, that drops to $8,223 — saving $2,116 per year. That's $685 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.
