How are property tax bills calculated in Grand Bay?
Property tax bills in Grand Bay are based on the assessed value of a home, not the market price alone.

For homeowners, this means two similar homes can receive different tax bills if their assessed values differ or if one qualifies for tax relief.

In Mobile County, the tax bill can range widely, with the 25th percentile at $483 and the 75th percentile at $1,144.
