If “millionaire” means assets, then about every house owner in CA is a millionaire.
If it makes you feel any better then one of the main issues Gavin Newsome (the likely next Gov. of CA) has is to eliminate restrictions on annual property taxes and have them raised somewhere between 5% and 10% of assessed value.
That means as much as $100k on one of those 2br/1ba million-dollar cottages.
you usually don’t claim your house on your income tax.
