Any advice on taking out a home loan in Singapore for a house in Australia?

Yes, if you look in the loan docs for S$ loans for Sg property, there is a clause enabling the bank to call for additional cash, but I've never personally heard of a case when it has been used. I have however heard of a number of cases where banks lending S$ to fund A$ purchases have called for more cash

There must have been an awful lot of loans made in 2007, where the LTV was well under 80% in 2008/9.Had the banks called for additional margin they would have killed an already very weak property market and made the problem even worse
