Tax Analysis

The estimated annual property tax is $6,000 across all districts. With a homestead exemption claimed, that drops to $4,688 — saving $1,312 per year. That's $391 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.
