Tax Analysis

The estimated annual property tax is $27,541 across all districts. With a homestead exemption claimed, that drops to $25,724 — saving $1,817 per year. That's $2,144 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.
