Hi Isa,
Thanks for visiting the forum.
You can read about Coronado and other beach areas (around Coronado, like Farallon…and in other regions, such as Pedasi) here on your Panama Insider website. I suspect in places like Coronado and Pedasi you can get a rental return of 6 or even 7% (samples from expats in Pedasi: https://internationalliving.com/magazine-issues/2015/january-2015/) but for specific real estate questions such as yours we recommend contacting an expert at Pathfinder International, IL’s exclusive real estate advertiser:
