I would be careful here. Laws like this are close to demonstrating a lack of respect for property rights and that is not a good direction for any democracy.<p>We have always had areas where the cost of housing was too high but the reactionary idea of taxing it to death is in effect the idea of that some property rights are important but others are not.<p>If any such idea was pushed then be sure that protection is applied to citizens of the country involved. Even this is dangerous as it tells foreigners that their money is welcome but their rights are subject to the whims of the times.<p>The real solution is, build more places to live. What is preventing  the building of affordable housing? Find that and fix that. The response is far more proper and rewarding than trying to force someone out of their property because you think they don&#x27;t deserve to own it if they don&#x27;t live in a set amount of time
