Tax Analysis

The estimated annual property tax is $10,154 across all districts. With a homestead exemption claimed, that drops to $8,385 — saving $1,769 per year. That's $699 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.
