Reprice or Refinance Your Home Loan?

Quick answer: Ask the current lender to reprice first, but compare the whole loan rather than the headline rate. Refinance when the net savings, structure or features justify switching costs and effort.

This guide answers one decision: Stay with the current lender and negotiate, or switch lenders. The comparison should use the same amount, time horizon and purpose wherever possible. That prevents a lower repayment or headline rate from hiding a longer or less flexible structure.

Start with the decision, not the product

All questions compare the lowest-friction repricing path with a full refinance. The practical test is whether the structure improves total cost, liquidity, flexibility or future borrowing position enough to justify the trade-offs.

Decision framework

1. Current rate vs realistic repriced rate. Compare the rate on the same balance and time horizon. A lower rate can still lose if the term or fees expand.
2. competing refinance rate. Compare the rate on the same balance and time horizon. A lower rate can still lose if the term or fees expand.
3. switching costs. Turn this into a number, document or contractual term before comparing the options. Avoid relying on a headline repayment alone.
4. features/offset. Put a dollar value only on features you will actually use, such as offset, redraw or flexible repayments.
5. break-even. Turn this into a number, document or contractual term before comparing the options. Avoid relying on a headline repayment alone.
6. future plans. Turn this into a number, document or contractual term before comparing the options. Avoid relying on a headline repayment alone.

Put the options on the same basis

Compare	What to check
Amount	Use the amount that will actually be financed or removed from cash/offset.
Time	Compare over the period you genuinely expect the debt or facility to remain in place.
Cost	Include interest plus fees and any final balance, balloon or residual.
Liquidity	Show how much cash or working capital remains after the transaction.
Flexibility	Check early repayment, redraw, reviews, employer dependence or other exit constraints relevant to the product.

Scenarios to test

$650k loan: 0.20% repricing vs 0.45% refinance improvement

Use $650k loan: 0.20% repricing vs 0.45% refinance improvement as a controlled comparison. Hold the transaction amount and time horizon constant, then compare cash retained, scheduled repayments, fees, total financing cost and any final balance. Change one assumption at a time so the real driver of the result is visible.

Low-LVR borrower with offset needs

For Low-LVR borrower with offset needs, start with the exact purpose and repayment source. Compare the alternatives on total cost, liquidity, security, documentation and what happens if the plan changes earlier than expected.

Questions borrowers are actually asking

Should I ask my existing bank for a lower rate before refinancing?

Ask the current lender to reprice first, but compare the whole loan rather than the headline rate. Refinance when the net savings, structure or features justify switching costs and effort.

How much can you realistically negotiate off your home loan rate?

A lower mortgage rate can still cost more if the purchase remains embedded in the mortgage for much longer. Compare the options over the same repayment horizon.

Will my bank match another lender’s rate?

Ask the current lender to reprice first, but compare the whole loan rather than the headline rate. Refinance when the net savings, structure or features justify switching costs and effort.

Does low LVR help negotiate?

Ask the current lender to reprice first, but compare the whole loan rather than the headline rate. Refinance when the net savings, structure or features justify switching costs and effort.

What to have ready before comparing

• Current loan balance, rate, remaining term and repayment
• Any package, offset, annual, discharge and switching costs
• Property value estimate and existing limits
• Your expected holding period and near-term borrowing plans

Check whether refinancing stacks up

If you want the structure reviewed against the actual transaction rather than a generic product comparison, Check whether refinancing stacks up. An initial enquiry is not a lender application and does not itself trigger a lender credit enquiry.
