Tax Analysis

The estimated annual property tax is $11,445 across all districts. With a homestead exemption claimed, that drops to $9,681 — saving $1,764 per year. That's $807 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.
