Tax Analysis

The estimated annual property tax is $14,910 across all districts. With a homestead exemption claimed, that drops to $13,507 — saving $1,403 per year. That's $1,126 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.
