I would agree with Conormc, why not just rent for a year, what is the big hurry with having to buy a house down there when you are not even sure if it will work out?. Especially if you already own 2 properties!. You will also put added stress onto your finances and health if your borrowings are sky high. The rent down the west is significantly cheaper than up here so if I were in you shoes I would definatly rent for the first year anyway and see how it goes, while renting you can still try to sell your apartment and if you are successful put the profit away and knock it off purchasing a house down there if it's all working out this time next year.
