One can rent a perfectly decent home in Cupertino with 3 bedrooms and 3 bathrooms for under $4,500 [1]. Price to rent ratios are very high for most SFH properties, so renting is often the right move. This will allow families to send their kids to public schools ranked among the best private schools in the nation for free, without any charter or magnet lotteries. I don't think rent for any comparable home in, say, Austin is more than $2,000/mo cheaper, or $40,000 before tax. That's a much narrower gap to justify than most of the hyperbole in this thread and especially narrow if both partners are working: job opportunities in the Bay Area are strong for almost all kinds of professions.
