"I don't think housing costs would drop that much, if at all."

That all depends on if people still want to live there, or can afford it. People tend to be sensitive to taxes, especially if they don't see it improving their lives. Businesses can be sensitive to this sort of thing too. And if they leave, people may leave too. California is already at a net negative when looking at joiners vs leavers. It's mostly been lower wage workers, but in recent years middle and high earners have also been leaving. The population is the same as it was 5 years ago.

"Property prices drop when property taxes go up, but mortgage payments tends to stay similar."

That might be roughly true for a person who just purchased and the federal property tax deduction is uncapped. A retiree who is getting a break on taxes is likely to see a big increase. Not to mention if the house is paid off, then there is no mortgage that could offset it.
