Tax Analysis

The estimated annual property tax is $13,790 across all districts. With a homestead exemption claimed, that drops to $12,398 — saving $1,392 per year. That's $1,033 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.
