Tax Analysis

The estimated annual property tax is $21,333 across all districts. With a homestead exemption claimed, that drops to $19,875 — saving $1,458 per year. That's $1,656 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.
