Tax Analysis

The estimated annual property tax is $13,479 across all districts. With a homestead exemption claimed, that drops to $12,098 — saving $1,381 per year. That's $1,008 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.
