With Interest rates being at a 49 year low of 3.00%, and Australian house prices being the highest in the developed world, it doesn't take a genius to figure out what is going to happen soon. Are 6.00% interest rates out of the question? We had them last year!
Many first home buyers will not be prepared for a doubling of their interest bill, but the Govt will have no choice but to raise rates.
LL in answer to your question, the Liberal party probably did say that, but they are in good company.
