● What this tells you

The §49.452 notice is the only public document that lists a MUD's exact tax rate, outstanding bond debt, and the assessed value used to compute your taxes — direct from the district, not the MLS. If the district is newer or has more bonds outstanding than its neighbors, your effective tax rate will be higher here than just across the street.
