I have a friend whose employer let her be remote, so she and her husband moved to Austin and bought a gorgeous house, dependent on her bay area salary. 8 months go by, employer changed their mind, didn't want remote workers any more. Gave her the option to come back, she was pregnant and they liked their big house, so they said no, thinking she would have no problem finding remote work.
6 months later she's still unemployed, considering giving up her career and just being a stay at home mom. They'll sell their austin house and downsize.
Point is: remote workers are always the first to get let go, and the income is not dependable.
Try getting one :) Remote job listing also means that there is an entire world of competition out there, much of which makes less than half of SFBA dev wages.
The parent said at SF Bay Area pay. The easiest way to get that is start in Bay Area, do a great job and then move. Once you've moved and want a new remote job with that salary it's much harder.
Why is that? The web is full of remote job offers.
