Tax Analysis
The estimated annual property tax is $7,044 across all districts. With a homestead exemption claimed, that drops to $5,722 — saving $1,322 per year. That's $477 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.
