I'm well over a year to living abroad but since I've set up a photographic company name I'll be able to get a self-employed insurance deal. Another option I have is joining a photo association and joining their group plan.
From what I understand it's difficult for a single individual not working to get insurance - could be wrong there though. I researched the whole thing a couple of years ago. So you might want to go with your company's insurance when you retire.
I estimated ~ $400/mo for my self-employed insurance. Don't have any company names though.
