Tax Analysis

The estimated annual property tax is $390,443 across all districts. With a homestead exemption claimed, that drops to $385,184 — saving $5,259 per year. That's $32,099 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.
