Joel,
Loke I have mentionned before I recommend the Caribbean also as the prices here are still very low comparing to the Pacific, which is overdeveloped and in the dry season to hot and dusty.
The Caribbean had beed forgotten by the Josefinos (the Costa Ricians from San Jose) who have been throughout Costa Rican history - there is no other way to put it- racist towards the vlack community in CR. So there had not been much development going on this side. It's been only since few years that people have started to discover the Caribbean. And let me tell you it is a paradise. The ocean front properties here go for a fraction of what same costs on the Pacific.

Good Luck,
