Tax Analysis
The estimated annual property tax is $13,816 across all districts. With a homestead exemption claimed, that drops to $12,399 — saving $1,417 per year. That's $1,033 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.
