Tax Analysis

The estimated annual property tax is $26,492 across all districts. With a homestead exemption claimed, that drops to $24,921 — saving $1,571 per year. That's $2,077 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.
