Tax Analysis

The estimated annual property tax is $11,658 across all districts. With a homestead exemption claimed, that drops to $9,671 — saving $1,987 per year. That's $806 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.
