Tax Analysis

The estimated annual property tax is $1,966 across all districts. With a homestead exemption claimed, that drops to $970 — saving $996 per year. That's $81 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.
