But is this not an hospitality buisness too that you don't recommend in a post before? And how many millons (dollars of course) you need to invest in such a buisness?
Not exactly. It's more of a healthcare / housing project with hospitality services bolted on, but the trick here is that you have a captive audience. And as far as investment goes, there are many many housing projects which are struggling here and many millions of dollars available for investment in property.
Market a real estate project as strictly for English-speaking expat over 50's, with a medical service managed and staffed by a large international healthcare company, hospitality services provided by someone like Radisson or Hilton, all staff 100% fluent in English, community center, activities and groups. And maybe even a sports bar. I think you'd get buy-in from some of the snow-birds. I was in Cabarete and I was surprised to see how many old and often single people were there.
