Tax Analysis

The estimated annual property tax is $14,225 across all districts. With a homestead exemption claimed, that drops to $12,829 — saving $1,396 per year. That's $1,069 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.
