Takes 15 days where I live to fully evict someone.
I was going to buy a house when I lived in SF and rent out the other 2 floors (to make it both reasonable to me and renters). After reading up on the laws I noped the fuck out of that.
This is why people rent to techies among other things.
The housing crisis is that there is less housing than people who want housing. Whether the homes are rented or owner-occupied has nothing to do with it.
