Tax Analysis

The estimated annual property tax is $7,147 across all districts. With a homestead exemption claimed, that drops to $5,821 — saving $1,326 per year. That's $485 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.
