Tax Analysis

The estimated annual property tax is $14,294 across all districts. With a homestead exemption claimed, that drops to $12,141 — saving $2,153 per year. That's $1,012 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.
