The biggest problem would be the American dollar....and btw, there is more stability in certain Central American countries than you suspect. This is not a new industry. There’s been stability in Costa Rica in the past 30 years than we can look forward to here in the next 30 - THAT THE POINT.
Panama used to be the ex-pat destination until Noriega blew up. There is always going to be something. Belize is nice but it’s already been discovered.
I’ve heard good things about Costa Rica. The real question is whether they allow you to have guns.
