Tax Analysis

The estimated annual property tax is $14,602 across all districts. With a homestead exemption claimed, that drops to $13,202 — saving $1,400 per year. That's $1,100 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.
