Tax Analysis

The estimated annual property tax is $10,709 across all districts. With a homestead exemption claimed, that drops to $9,358 — saving $1,351 per year. That's $780 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.
