Higher taxes is not enough. Taxing property means you confiscate it piece by piece, the owner will have to pay or lose it, but given enough time the owner will pay more than the value of the property. Why go that slow and not go for it, confiscate all properties and be happy with it? You can always follow examples from the likes of North Korea. Just in case you don't get it: you can ask for taxes when you provide services, not when you vote to raise taxes. Not sure what are more expensive services the empty Chinese-owned houses require to tax for it. And blaming Chinese investment is just a straw man: if all the houses would be occupied by pure-breed white Caucasian Americans (that's a joke) who would you blame, Martians?
