Tax Analysis

The estimated annual property tax is $28,253 across all districts. With a homestead exemption claimed, that drops to $26,428 — saving $1,825 per year. That's $2,202 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.
