Tax Analysis

The estimated annual property tax is $15,526 across all districts. With a homestead exemption claimed, that drops to $13,295 — saving $2,231 per year. That's $1,108 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.
