Have a ton of cash and come on down. It ain t cheap in Key West. Jobs are virtually zilch, highly-prized, and low-paying. Also suggest that you closely monitor the Key West websites that provide news, weather, sports...and jobs...and rentals.
just do it.. i moved out of the state not knowing anyone in the area at 17 and i made it work. Just make sure you have a good amount of money to start out until u get a job... good luck
Do it if you really want to
