Tax Analysis

The estimated annual property tax is $9,755 across all districts. With a homestead exemption claimed, that drops to $8,412 — saving $1,343 per year. That's $701 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.
