Tax Analysis
The estimated annual property tax is $6,398 across all districts. With a homestead exemption claimed, that drops to $5,086 — saving $1,312 per year. That's $424 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.
