Tax Analysis

The estimated annual property tax is $5,749 across all districts. With a homestead exemption claimed, that drops to $4,440 — saving $1,309 per year. That's $370 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.
