It will be interesting to know what you learn from others here. In my experience, Latin American countries that have lower costs also have few facilities like these because families live in multi-generational households, and family are the primary caretakers. We also observed this in Yugoslavia and Germany (not the low cost - just the multiple generations) - grandparents on the ground floor, married child and family upstairs, sometimes even a third flat in the home with young adult children or other relatives.
We also have a number of acquaintances who have moved to Costa Rica or Mexico in their younger senior years, but return to the US as their health fails and they need more help with appointments, daily activities, etc.

I believe only Mexico has established this type of elderly care, while Panama recently started to build one.
