Tax Analysis

The estimated annual property tax is $14,048 across all districts. With a homestead exemption claimed, that drops to $12,248 — saving $1,800 per year. That's $1,021 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.
