You can’t even rent an apartment in Key West if you’re making $19-22/hr unless you’re living with 1-2+ roommates and have NO debt whatsoever. Otherwise, you’d need to live further up. I don’t think you could live in Marathon (1 hour away) on that and then you’re talking about needing a car, gas, etc on AT MOST $3500/mo before taxes, health insurance (if they even offer it), and retirement (ha). The Upper Keys are might be more “affordable” (relatively 😂) but even further.
