I think you need $13 million to become resident in Singapore, so it’s for the super rich. Malaysia next door is much bigger, and much cheaper, but humidity is infernal. I believe residency isn’t too hard to obtain though. Asheville seems nice from the online brochure. I think it is a great shame that Mexico, with it’s rich cultural heritage and beauty doesn’t do more to cash in on the large number of US retirees. On the other hand if you see what the British have done to Spain, perhaps it wouldn’t be such a good idea. Anyway here are a few useful links.

My dream would be a place in somewhere like Chamonix, Lake Como, or Cap D’Antibe for part of the year and perhaps Bermuda or Hawaii for the other part.
