Thanks for responding Mike. I appreciate your input.
As you pointed out, hard to give specifics with such a broad question. My intention is to gain a 10000 foot view to start with regards to legalities of ownership (example, Costa Rica allows fee simple ownership, but through a corporation owned by the investor), lending - will the country you wish to invest in have banks willing to fund or is it best to find funding within country of citizenship... Local issues like safety of market, economy, access, will be necessary as I focus down into specific markets, condos vs houses vs developments.
Overall, my intention is to STR the property, use for personal vacation a couple times per year. ROI minimum is 15% for my current US investments. 20% would be better. Looking around central America, there appears to be plenty of development and vacation home in the airbnb and VRBO market. Recent international travel has been diminished vs drive-to destinations in the US for STR's, so one of my questions is about the viability of out of country vacation rentals currently and projections going forward.
I hope that helps focus some perspective. Again, thanks for helping shape the direction I'm trying to gain perspective from.
