Tax Analysis

The estimated annual property tax is $1,771 across all districts. With a homestead exemption claimed, that drops to $873 — saving $898 per year. That's $73 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.
