Tax Analysis

The estimated annual property tax is $9,940 across all districts. With a homestead exemption claimed, that drops to $8,173 — saving $1,767 per year. That's $681 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.
