Tax Analysis

The estimated annual property tax is $19,349 across all districts. With a homestead exemption claimed, that drops to $17,900 — saving $1,449 per year. That's $1,492 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.
