Tax Analysis

The estimated annual property tax is $6,136 across all districts. With a homestead exemption claimed, that drops to $4,823 — saving $1,313 per year. That's $402 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.
