Tax Analysis

The estimated annual property tax is $26,533 across all districts. With a homestead exemption claimed, that drops to $25,024 — saving $1,509 per year. That's $2,085 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.
