...another retirement location? If anyone can offer any information on Costa Rica, Panama, or another retirement destination (outside the U.S) it would be greatly appreciated. We would be interested in the following:
1) the cost of a modest place to live
2) Relative closeness to conveniences such as groceries, hospitals, banks, etc.
3) climate
4) proximity to the beach
5) overall cost of living
6) Approximate population of americans in that area
Any information given would be deeply appreciated. Thankyou!
