Tax Analysis

The estimated annual property tax is $15,110 across all districts. With a homestead exemption claimed, that drops to $13,714 — saving $1,396 per year. That's $1,143 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.
