Tax Analysis

The estimated annual property tax is $16,469 across all districts. With a homestead exemption claimed, that drops to $15,067 — saving $1,402 per year. That's $1,256 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.
