Tax Analysis

The estimated annual property tax is $76,378 across all districts. With a homestead exemption claimed, that drops to $74,204 — saving $2,174 per year. That's $6,184 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.
