Tax Analysis

The estimated annual property tax is $1,335 across all districts. With a homestead exemption claimed, that drops to $654 — saving $681 per year. That's $55 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.
