Refinancing

How often can you refinance a home loan?

There is no universal waiting period, but frequent refinancing can create costs and approval problems.

Short answer

You can technically refinance whenever another lender approves the application and the current loan can be discharged. There is no standard Australian rule requiring you to wait a set number of years. In practice, refinancing too frequently can produce repeated fees, credit enquiries and short-lived loans that need a convincing explanation.

Review regularly, refinance selectively

Checking your rate every six to twelve months is sensible. That does not mean moving every time. First ask the existing lender to review its pricing, then compare the net benefit of suitable alternatives. A refinance should solve a real issue such as excessive cost, unsuitable features, cash-out needs or a policy mismatch.

Calculate switching costs and the break-even period.
Keep the remaining loan term consistent in comparisons.
Check cashback and broker clawback conditions.
Avoid multiple speculative applications at once.

Why lenders notice short loan histories

A new lender may ask why a recently settled loan is already being replaced. Frequent moves can suggest that the applicant is chasing incentives, experiencing cash-flow difficulty or repeatedly changing the loan purpose. A clear financial benefit and clean repayment record make the reason easier to understand.

The break-even period should guide timing

If refinancing costs $1,000 and saves $100 each month, the simple break-even period is ten months. Moving again after six months would normally leave the first change behind on costs unless a cashback or other benefit genuinely covers them. Repeat the calculation each time using discharge fees, registration charges, valuation or application fees, package costs, break costs and any LMI. Do not count an incentive until its eligibility and payment conditions are confirmed.

Credit enquiries are not the only issue

A credit enquiry does not automatically prevent approval, but several applications in a short period can prompt questions. More importantly, every refinance requires updated income, expense and debt verification. Your borrowing position may weaken if rates, policy, property value, employment or business income changes. Approval from six months ago is not transferable. Apply only after a comparison identifies a suitable lender, rather than submitting several applications to test possible outcomes.

A practical review cycle

Review the loan after material rate changes, at the end of a fixed period, when your property value or LVR improves, or when your needs change. Start with a pricing request to the current lender. If the offer remains uncompetitive, calculate external options using the same balance and remaining term. Refinancing every few years can be reasonable when the savings are clear. Refinancing several times a year is harder to justify and can create more work and cost than value.

Questions to ask before you proceed

What is the net saving after every discharge, application, valuation and ongoing fee?
How long is the break-even period if the remaining loan term stays the same?
Which valuation, income or policy issue could still change the approval or pricing?

Key takeaway

There is no fixed schedule. Refinance when the measurable benefit comfortably exceeds the cost and disruption.
