Note that repealing prop13 would probably not raise property taxes overall. It would spread them more fairly across all owners, instead of the current arrangement of newcomers subsidizing established owners.
Not necessarily. Prop 13 also gutted California's funding for schools. They lost 1/3 of their funding overnight when Prop 13 passed. One would hope that repealing Prop 13 would also undo at least some of that underfunding, considering California is 41st among states in CoL-adjusted per-pupil spending.

A straight-up repeal of Prop 13 would repeal rate limits on property taxes as well as assessment increase limits (both are part of Prop 13) and probably lead to jurisdictions, over time, increasing property tax rates and overall property taxes. It would probably reduce increases in sales, income, and other taxes, which currently are used in place of property taxes because they have no Constitutional rate limits.
That's a good point, your comment led me to research a bit more, and I learned that prop13 did in fact caused local governments to rely more heavily on sales taxes. Ironically this has contributed to the perverse incentives against building housing inventory, since commercial zoning is more likely to generate sales tax and other business-related tax revenue.
