Raising multiple young children with their own individual bedrooms in one of the most expensive cities in the country is an edge case.

That said, it's entirely doable, especially in an age where FAANG companies are paying huge compensation in that area anyway.

Obviously, it doesn't make sense for someone with a median non-tech salary to try to raise multiple kids in one of the most expensive areas in the country. For tech people working tech jobs, it still works out fine though.
