Tax Analysis

The estimated annual property tax is $14,379 across all districts. With a homestead exemption claimed, that drops to $12,220 — saving $2,159 per year. That's $1,018 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.
