This has been a thing in Vancouver for a while now. Scammers would rent fully furnished luxury apartments on airbnb for a couple of weeks, and "show" them to potential tenants as if they were the owner or a person needing to sublet, signing leases, collecting first month+deposit payments from like a dozen different people.

Of course this only duped the most gullible, since nobody should be paying rent+deposit for a $3000/month apartment in cash. Then of course when it came to be end of month and time to move in, the scammer would be long gone.
