Tax Analysis

The estimated annual property tax is $13,573 across all districts. With a homestead exemption claimed, that drops to $12,183 — saving $1,390 per year. That's $1,015 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.
