Tax Analysis

The estimated annual property tax is $95,406 across all districts. With a homestead exemption claimed, that drops to $93,176 — saving $2,230 per year. That's $7,765 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.
