Tax Analysis

The estimated annual property tax is $1,515 across all districts. With a homestead exemption claimed, that drops to $1,462 — saving $53 per year. That's $122 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.
