only one small point if you're a USC. When you buy your house, you have to calculate the purchase price at that day's exchange rate. When you sell it, you may have capital gains. The selling price, and hence gain, is calculated at that day's rate of exchange. So if you buy when the exchange rate is, eg, $1.50 and sell when it's $2.00, you'll not only have the 'real' gain, but also have the 'extra' gain because of the exchange rate. (and there's something complicated about it not working in your favor in the event that you sell at a loss). All this is just to say that with the rate fluctuating, as it is right now, and is expected to be for the rest of the year, you might want to think a little about timing your transfer and purchase (admittedly this is difficult given the already difficult hassle of house buying). These rules also apply when you re-mortgage - it's like a sale for purposes of figuring capital gain.
