Tax Analysis

The estimated annual property tax is $20,610 across all districts. With a homestead exemption claimed, that drops to $19,148 — saving $1,462 per year. That's $1,596 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.
