I would require more information as to the definition of "occupied". I used to live in Vancouver, a city struggling with that definition. Unless you are willing to send unannounced inspectors it is very difficult to determine whether the owner is actually living in an apartment. In most cities "occupied" simply means owned by an individual. Whether that person actually resides in the unit is another matter.

Take a look at this pic to see vancouver's problem: https://images.app.goo.gl/uGmMJcwyNvXQUWdQ6

What do you think the real occupancy rate is of those buildings? 60? 70% at best? (They are all residential except for the few commercial ones, those with entire floors lit.)
