I think a progressive tax like income in total residential property value. Numbers off the cuff but something like <$1m is zero. $1-3m is 1%... Etc. Make the top rate untenable to own more than say $50m in residential like 10% + top rate for anything held under obscure ownership structure. This way peeps can own a normal home at no cost, even have an investment property. But the person with 300 apartments who buys another 10 every year is encouraged to move their money to alternate assets.
