This is already true for those in silicon valley, where you'll see a single family home with 6-8 cars parked in front -- each room rented out, garage split in two to rent out to two people, a tool shack in the garden rented out to another person, and so on. And the cost of rent for one of these rooms still costs an arm and a leg.

And to make matters worse is california's tenant laws. You just pay 2 months of rent and stop paying after, and tenant law kicks in guaranteeing you protection from eviction -- it's how friends I know running airbnb lost their house to grifters
