Or, keep your salary and work remotely for an SF co. Best of both worlds! But, you'll have to do without the longboards if you don't move to a properly hip location.
Assuming that elsewhere you would do 30/30/40 % split on rent/savings/spend, then as long as you're making 40%+ more income (than elsewhere) you're okay to spend 50% on rent because you can save just as much or more.
The amount of choice in employer I have as an individual is also much greater here.
Still, I'll probably head back to one of those "small" towns soon. Not really worth it here for me personally, despite the employer-choice and the $.
