If you're thinking of investing in overseas property don't exclude Mauritius from your research. According to many articles I've read it's a property hotspot - see http://www.guardianweekly.co.uk/?page=editorial&id=749&catID=13. Until recently the law prohibited overseas residential investors but all that has changed since the island's traditional industries have taken a downturn.
Take a look at http://www.emeraldheightsmauritius.com/index.php?p=249&pp=0&page=Life which gives some interesting facts about living in Mauritius and advice on how to buy.
