Tax Analysis

The estimated annual property tax is $24,944 across all districts. With a homestead exemption claimed, that drops to $23,450 — saving $1,494 per year. That's $1,954 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.
