This doesn't come across as convincing to me. This would require that in any given community of 10000 dwellings, literally every single unit is a rental property, and that every single unit is vacated and has a new tenant move in every year. That might be true in certain specific communities like university residences, but I very much doubt it's the case in any ordinary urban community. In the US home ownership numbers are around 65%[1] (not 0%), and people on average only move about 11 times in their life[2] (not once per year). It seems to me entirely reasonable to assume that in a community that touts its low vacancy rate of 3.5%, there must still be a not insignificant absolute number of properties that remain unoccupied for a month or more every year. If that number truly were near-zero, then nobody should have a problem with a vacancy tax, or a squatter's rule designed to grant rights to actual members of the community who want to use a property left vacant for longer than a couple of months.
