Tax Analysis

The estimated annual property tax is $19,251 across all districts. With a homestead exemption claimed, that drops to $17,803 — saving $1,448 per year. That's $1,484 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.
