I say you have to decide on whether or not your happy to pay circa $46kAUD for a $50k US property.
There is a higher chance of the AUD to drop than there is of the AUD riding higher.
Ie. How much higher do you think the AUD can go up to? VS
How low can the AUD drop?

People are now starting to say that the AUD can run up to the 1.50 and. Parity against the Euro…
Is this possible? Definitely… If China is still strong and Europe doesn’t fail.

But if The Eurozone collapses (which is what I believe will eventually happen) than Chinas export will reduce as Europe is one of Chinas largest trading partner, if China slows down than their appetite for commodities will reduce and if commodity demend reduces so will the Aussie dollar. This is because the AUD is know as a risky currency and has a strong correlation with commodities.

If it drops where will it go down to? During the peak of the GFC, the AUD just below $0.60.
If Euro collapses, it’s going to hit the world hard.

So this comes back to your thoughts in the present, the right here right now situation.

My thoughts… It’s a good time to get your first capital investment/deposit transferred from AUD to USD.
$1 for $1 isn’t bad.
If AUD rises, great buy some more properties – transfer more AUD or borrow in the US at lower rates.
If AUD drops, great transfer some money back OR borrow in the US and use the rental return to buy more.

At the end end of the day if the AUD drops that $50k property is goin to cost you $90-100k – how you going to feel about that?

If you find a property now:
A) do it now rather than trying to pick the high
lets me know where this property is so I can look into properties in the suburb

Bit long winded but hope that helps!
