Tax Analysis

The estimated annual property tax is $10,003 across all districts. With a homestead exemption claimed, that drops to $8,658 — saving $1,345 per year. That's $722 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.
