Tax Analysis

The estimated annual property tax is $31,908 across all districts. With a homestead exemption claimed, that drops to $30,330 — saving $1,578 per year. That's $2,528 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.
