Tax Analysis
The estimated annual property tax is $4,186 across all districts. With a homestead exemption claimed, that drops to $2,455 — saving $1,731 per year. That's $205 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.
