Once you leave the Bay Area, it becomes exponentially more difficult to come back, so the what-if scenario of this employment expiring becomes a real threat to financial viability.
So the pitch is: 1) De-locate to a more reasonable real-estate market where you can actually buy the house you want/need. 2) Rent-out your existing SFBay property if you own, and get additional income (even minus property management cut) 3) Get a bonus 4) Maybe move closer to family outside of SFBay.
What's not said: 1) Career mobility is limited to whatever market you move to and within Zapier. 2) Salary probably likely won't make same leaps as if you stayed 3) You might have family in the SFBay - could be a downside to move away
If you're career-stable and open to move it can be a good deal.
