Tax Analysis

The estimated annual property tax is $14,321 across all districts. With a homestead exemption claimed, that drops to $12,165 — saving $2,156 per year. That's $1,014 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.
