Tax Analysis

The estimated annual property tax is $7,753 across all districts. With a homestead exemption claimed, that drops to $6,429 — saving $1,324 per year. That's $536 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.
