Tax Analysis

The estimated annual property tax is $65,950 across all districts. With a homestead exemption claimed, that drops to $64,023 — saving $1,927 per year. That's $5,335 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.
