Tax Analysis

The estimated annual property tax is $14,337 across all districts. With a homestead exemption claimed, that drops to $12,945 — saving $1,392 per year. That's $1,079 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.
