Tax Analysis

The estimated annual property tax is $9,398 across all districts. With a homestead exemption claimed, that drops to $8,052 — saving $1,346 per year. That's $671 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.
