Tax Analysis
The estimated annual property tax is $19,664 across all districts. With a homestead exemption claimed, that drops to $18,212 — saving $1,452 per year. That's $1,518 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.
