Tax Analysis

The estimated annual property tax is $14,678 across all districts. With a homestead exemption claimed, that drops to $13,277 — saving $1,401 per year. That's $1,106 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.
