> What will work, very few rich people would ever allow: a graduated tax on every additional property you own. Own one house that you live in as your primary residence? Low property tax. Own 30,000 units? Massive tax bill that encourages you to flee from the idea of using real estate as a glorified stock market. Perhaps a graduated capital gains tax instead? 100% capital gains tax on any residential zoned property (whether a structure on it or not), for 3+ properties owned by any natural person, and 100% capital gains on all residential zoned property owned by non-natural persons. With an exception for the initial builder/developer. Either helps address lack of affordability for purchasing a home, but both would likely significantly drive up rental costs (the capital gains version long-term increasing rental costs, while the property tax version would immediately cause a huge spike in rents, but the beneficial effects would also be more delayed for the capital gains version too). I can't think of a way to prevent driving up the price of rent without direct price controls, and those are even more anathema to some folks than paying taxes.
