If you were faced with that situation, I'd encourage you to do thorough research on it before making that decision. I have a number of people I can get you in contact with who could give you a realistic view of what the island will cost (ex PR controllers who returned stateside after realizing the true cost of living in PR). For instance, you'll pay far more in taxes in PR then the vast majority of the US. A 33% tax bracket starts once you hit 61k for PR income tax. On top of that, their 11.5% sales tax ranks #1 when compared to the rest of the US (there's talk of raising it to 16%). Given that it's a US Commonwealth, most non-food/medicine items are also subject to an 11.5% import tax.
I'd encourage anyone to do the same in terms of getting in contact with current/former controllers whether it be, Puerto Rico, California, New York, Alaska, Hawaii, etc to get a complete picture of taxes, cost of living, etc.
