Except they don't, taxing single house owner is just cost of living increase any time area gets gentrified or more desirable

It's basically excuse to get rid of poor that made a mistake of buying a house in area that turned more expensive 2 decades after.

Tax anything after first house, sure, but taxing house by value is terrible idea that never actually worked in a way proponents are saying it would

the incentive is if they sell they realize their gains and are left much richer
