Tax Analysis

The estimated annual property tax is $9,012 across all districts. With a homestead exemption claimed, that drops to $7,254 — saving $1,758 per year. That's $605 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.
