Tax Analysis

The estimated annual property tax is $14,625 across all districts. With a homestead exemption claimed, that drops to $13,225 — saving $1,400 per year. That's $1,102 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.
