I still don't know what this means. We would still be in the parish. Why would we lose homestead exemption?
Parishes have a right to tax the homes within their boundaries. This is subject to the homestead exemption meaning that part of the value of the property/house is not taxed.
Towns and cities also have the right to tax property. Their taxes are not subject to the homestead exemption. For example, I live in Lutcher in St. James Parish. St. James Parish property taxes are subject to the homestead exemption. Lutcher property taxes are not. While town property taxes are usually not a large amount they are in addition to the parish property taxes.
