Tax Analysis

The estimated annual property tax is $22,667 across all districts. With a homestead exemption claimed, that drops to $21,208 — saving $1,459 per year. That's $1,767 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.
