Stop relying on local property taxes to fund the schools. That’s a US thing that isn’t replicated in most other well-off countries.

The closest thing Germany has to US-style annually-billed property tax is Grundsteuer, and for homeowners, it’s low triple digits at most. It pays for neighborhood streets, sidewalks, storm drains, and (I think) the fire department. We do pay a pretty hefty transfer tax when we buy property - I think it was about 5% of the purchase price, but that’s a one-time thing.

Schools are funded out of general revenues, mostly personal and corporate income taxes, assessed nationally. Each state has its own school system, with differing structures and standards.
