Tax Analysis

The estimated annual property tax is $1,310 across all districts. With a homestead exemption claimed, that drops to $713 — saving $597 per year. That's $59 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.
