Tax Analysis
The estimated annual property tax is $8,035 across all districts. With a homestead exemption claimed, that drops to $6,702 — saving $1,333 per year. That's $559 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.
