Tax Analysis

The estimated annual property tax is $14,741 across all districts. With a homestead exemption claimed, that drops to $13,339 — saving $1,402 per year. That's $1,112 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.
