I think there is a big problem with housing affordability in many countries. It’s also a promising investment because, as Mark Twain says, “Buy land, they’re not making it any more.” This makes land unlike other commodities (you can just make more iPhones or whatever.) The situation leads to some movements which see land as inherently a public good, such as Georgism, on which there is a good Wikipedia article.
I think it would also be nice if there were some kind of scheme whereby property tax is low for a first home, but increases when you own more than one.
Every property tax I’ve ever paid has that property. At least the first one is lower than the rest. It’s frequently called a homestead exemption or a primary residence exemption.
