What costs are involved in refinancing?
Typically: discharge fee ($200–$400), new application fee ($0–$600), legal/conveyancing ($500–$1,000), and sometimes lenders mortgage insurance if your LVR has changed.
How much rate reduction makes refinancing worthwhile?
A reduction of 0.5% or more is generally worth investigating. With a $500k loan, 0.5% = ~$180/mo saving. Run the numbers with your specific situation.
How often should I review my rate?
At least every 2 years. The Reserve Bank of Australia sets the cash rate and lenders adjust; loyal customers often pay more than new customers.
