Hi Char, first of all the good news: you are in the USA and things are pretty similar to life and standards of living in a small costal, beach town in anywhere USA only better ;-)
the bad news is that the economy is just as bad as everywhere else. I'm not too familiar with the COL in RIncon but I do know that this is the season to be here: winter birds, tourists, surfers, etc. the place is jumping. can you come down for the season to give it a try?? there are great short term rentals in the area and i am sure an english speaking clerk would be a great help even in a Walgreens, Dunkin Donuts or Marshalls in the area(we have tons of those.) if you are looking for a nice warm winter, then this is the place. AND it's USA!!!! that's the best part!!
Suerte!!
