Tax Analysis

The estimated annual property tax is $192,470 across all districts. With a homestead exemption claimed, that drops to $189,362 — saving $3,108 per year. That's $15,780 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.
