I thought you said without much work or stress?
I'd buy a vacation condo someplace that has a rental management service who keeps the place rented out and provides guest/maid service.
Rental income, zero work, go there yourself and relax anytime; and the place should appreciate in value should you ever want to sell it. That's no work and zero stress.
Perhaps someplace in Costa Rica (e.g. Los Sueños) or Panamá. You'd need mid-six figures. Return just via rental income may not be huge, but it's almost risk-free.
