Tax Analysis

The estimated annual property tax is $19,588 across all districts. With a homestead exemption claimed, that drops to $18,144 — saving $1,444 per year. That's $1,512 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.
