This hits it on the nail i.e. First of all there's all the money-printing that the Americans and the Europeans are doing, which will lead to inflation and therefore a potentially big rise in interest rates at a time when a lot of people are already struggling.
Second, our banks have to borrow dough from international markets to fund a good whack of their home loans. This year they'll need about $140 billion -- and if the European debt crisis blows up further, our banks may soon find it much more expensive to borrow.
The very best strategy for the next few years is save and collect the 7% - soon to be 10% - interest on your savings and at the same time watch house prices stand still or slide.
