To expand on pelican’s post – as a general rule, overseas borrowing commitments should be met out of income in the same currency. So if your mortgage payments are in Japanese yen, and your rental income is in Aussie dollars, then you’ve got a mismatch which exposes you to exchange rate risk.
The big companies mitigate this risk by entering into some form of hedging arrangement (usually with or through a bank) to “swap” their income stream into Japanese yen, or their mortgage obligations into Aussie dollars. It’s a sophisticated form of insurance, and there’ll obviously be a premium. But at least you’ve capped your risk. Unfortunately, this product is unlikely to be available to you unless you’re working off a few million dollars in cashflow.
Think this is silly? You only have to dig up stories of all those poor sods back in the eighties who borrowed low interest money from Lichtenstein and other fashionably exotic places, and literally lost their homes (or came close to it) when the exchange rates turned against them in a big way.
