Here is a great video provided by Chris from PanamaForReal.com. No where in Panama is without problems, just as no where in the world, but Chris has done a nice job of showing some of the reality of the town of Coronado, and has painted a great picture of where the pretty beach town is headed.
Prices are still very affordable here when you consider other beachfront communities around the world, especially that are being developed and modernized at a pace as quicly as Coronado. If it were me spending my hard earned dollars, both from an investment standpoint, and a quality of life in Panama standpoint, Coronado is #1 on my list!
As Chris mentioned in the video, you don't have to buy inside the gates of Coronado to enjoy it's charm either. Pretty much every popular beach development selling today is within 30 minutes of Coronado, so prices and lifestyles vary greatly. It's something that has to be seen to be appreciated.
