Tax Analysis

The estimated annual property tax is $40,798 across all districts. With a homestead exemption claimed, that drops to $39,054 — saving $1,744 per year. That's $3,255 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.
