You're only looking at very cheap places though and I'd argue it's not going to be a very exciting lifestyle. Those rates seem a bit low - to me. I'm used to places charging $200+/night in the bay area. I'd hate to have to go through a check-in process and what not just to sleep with someone! I'd not bother. You're also not accounting for the fact that the children are "renting" a room from their parents - not an apartment. So, you need to look up the median cost of a room in SF. It's closer to $1200-2000/month. Back in the not worth living with your parents money. I think people who live with their parents probably just aren't having much sex unless their respective partners don't live with their parents. And - honestly - that's about what I've heard from people I know who live with their parents. They might get laid but it's not happening at their parent's place much at all. Btw, there is no cost saving in this equation - the children are merely taking advantage of their parent's wealth. Seems the privileged and celibate will reap some weird financial rewards at some point... at the cost of not getting laid and having a limited set of partners.
