Tax Analysis

The estimated annual property tax is $10,738 across all districts. With a homestead exemption claimed, that drops to $9,384 — saving $1,354 per year. That's $782 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.
