&gt; What happens if legislation is passed that more or less prevents people from owning property that&#x27;s not their primary residence? Like: if you don&#x27;t live in it more than 190 days a year, you pay a really high property tax on it.<p>That already exists in a way - there&#x27;s the concept of a primary residence tax deduction, which is (more or less) what the name sounds like.<p>It varies widely by jurisdiction, (not just country, but state and local government as well), but the idea of trying to differentiate residents from landlords in tax policy is nothing new.
