Tax Analysis

The estimated annual property tax is $13,157 across all districts. With a homestead exemption claimed, that drops to $11,771 — saving $1,386 per year. That's $981 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.
