I can't say a lot about Rincon because I don't know but Mayaguez is the most American like city here with the highest rate of english speaking people I have seen.
Living costs on most everything is a little expensive here except for service related items (car repairs, appliance repairs, etc). Expect a 5 - 10% increase in living expenses.
You will need a car to get around unless you live in Palmas del Mar and then you will need a golf cart, there is a car rental on site if you need to go further than the onsite.
Things to like. 1. The weather 2. Simpler Life 3. Tropical Fruits/Nuts everywhere 4. Less regulations on things I care about (homeschooling) 5. Tax system that is not the IRS 6. More community minded people, probably more like the states in the 70/80s. 7. I have a personal swimming pool, tennis court, basketball court and decent sized house for less than the one I left in Atlanta.
I've never had a problem here or felt in danger.
I'm in Atlanta now, but have definitely been mulling PR over.
Heard the same thing about east vs west sides of the island.
Can you list a few?
Some questions I have, if you don't mind: How do you like Rincón? Do you need a car if in SJ? How much is Spanish used over English? Are living costs cheaper? Thx
