Tax Analysis

The estimated annual property tax is $21,176 across all districts. With a homestead exemption claimed, that drops to $19,731 — saving $1,445 per year. That's $1,644 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.
