> People talk about taxing granny out of her house, but they conveniently forget to mention that granny is keeping half a dozen people homeless by hoarding an underutilized property

Where are you getting that from?

In most cases when granny sells her house and moves due to high taxes the buyer will be a single family that will live in the house. In the vast majority of cases that family will have less than half a dozen people, and in the vast majority of cases they will not have been homeless before.
