The lease terms would be important. Not all leases let you out whenever you want.

Plus, if a sizable portion of that household income is in the form of stock or a bonus, that isn’t showing up each month in the paycheck, lowering the monthly cash flow. If there is a layoff early in the year before the bonus pays out, and you can’t exit the lease, that would be a bad spot to be in.

There is still risk on the table, depending on how some of this is structured.

With the numbers I had it only takes 1-2 years to save 1 year of runway, so just do that first (presumably you've had a chance to save before getting your 250-300k income anyway). I suppose that the type of people to spend 6k on rent probably aren't saving much, but they could if that were their goal for some reason.
