Tax Analysis

The estimated annual property tax is $8,421 across all districts. With a homestead exemption claimed, that drops to $7,082 — saving $1,339 per year. That's $590 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.
