Refinancing Traps: 10 Home Loan Mistakes to Avoid

Refinancing can reduce interest, change loan features or consolidate debts, but a lower advertised rate does not automatically produce a better result. The key test is whether the expected benefit exceeds the switching costs and remains suitable after considering the new term, valuation, fees and risks.

Use the following refinancing traps as a practical checklist before authorising an application or closing your existing loan.

1. Comparing the headline rate instead of total cost

A lower interest rate can be offset by application, valuation, settlement, discharge, package and ongoing fees. Fixed loans may also have break costs. Compare the repayment, total interest, fees and retained features over a realistic period, not only the first month.

A comparison rate can assist, but it is based on a standard example and may not reflect your balance, term, features or loan package. Request a documented comparison using your expected loan amount and term.

2. Ignoring the break-even period

The break-even period is the time required for expected savings to recover the switching costs. If you plan to sell, repay the loan, refinance again or move before that point, the change may not deliver the expected benefit.

Include all known switching costs and use conservative savings assumptions. Interest rates, repayments and personal circumstances can change, so the result is an estimate rather than a guarantee.

3. Resetting the loan to a longer term

Extending a loan with 18 years remaining back to 25 or 30 years may reduce the scheduled repayment while increasing the time interest is charged. This can raise total interest even when the new rate is lower.

Compare the new loan using a term close to the remaining term of your current loan. If a longer term is needed for cash-flow relief, document the trade-off and consider whether voluntary extra repayments are available and affordable.

4. Treating cashback as a saving without testing the loan

A cashback offer is not a substitute for comparing rate, fees, features and total cost. Eligibility conditions, minimum loan sizes, settlement deadlines, clawbacks or package requirements may apply. A one-off benefit can be outweighed by a higher ongoing cost.

Compare the proposed loan both with and without the cashback and read the offer terms before relying on it.

5. Underestimating valuation and equity risk

The new lender normally assesses the property offered as security. If the valuation is lower than expected, the LVR may rise and change the available rate, loan amount or lender’s mortgage insurance position. The application could require more evidence or may not proceed.

Do not commit cashback, debt payout or renovation funds until the valuation and formal approval conditions are understood.

6. Refinancing fixed-rate debt without obtaining a payout figure

Fixed-rate loans can have break costs that change with market conditions and the time remaining. Ask the existing lender for a current payout figure and confirm how long it is valid. Also check discharge timing, package changes and any linked accounts.

7. Consolidating short-term debts over a home-loan term

Moving credit-card, personal-loan or car debt into a mortgage can reduce the immediate repayment, but the debt may then be secured against your home and repaid over much longer. Total interest can increase if the balance is not cleared sooner, and continued use of cleared credit limits can recreate the debt.

Use a separate loan split where available, set a repayment period appropriate to the consolidated debt, and consider reducing or closing facilities that are no longer needed. If repayments are already difficult, contact the lender’s hardship team or a free financial counsellor before taking on new credit.

8. Losing useful features or flexibility

Check whether you will lose an offset account, redraw access, additional-repayment flexibility, portability, split-loan options or package benefits. Features have value only when you will use them, but losing a suitable feature may cost more than a small rate difference.

9. Making multiple applications without a coordinated strategy

Each lender has different policy, documentation and valuation requirements. Several applications in a short period can create unnecessary enquiries and inconsistent information. Compare likely policy fit first, then proceed with a deliberate application supported by complete documents.

10. Closing the existing loan too early

Do not cancel direct debits, close linked accounts or assume the refinance is complete before settlement is confirmed. Keep making required repayments and maintain insurance. Review the final settlement and payout figures and confirm that old facilities have been closed as intended.

A practical refinance comparison

• Current balance, rate, repayment and remaining term.
• Current payout figure, discharge fee and any fixed-rate break cost.
• Proposed rate, comparison rate, fees and loan term.
• Estimated repayment and total interest over the comparison period.
• Break-even time after all switching costs.
• Valuation, LVR and possible mortgage-insurance impact.
• Features gained or lost.
• Debt-consolidation term and security consequences.
• What happens if rates rise or income and expenses change.

Should you ask your existing lender first?

Often, yes. Your current lender may offer a lower rate or another product without a full external refinance. Compare any retention offer with external options and include internal switching fees, features and the remaining term. Staying is not automatically better, but it can avoid some switching costs.

Frequently asked questions

How do I know whether refinancing will save money?

Compare the current loan with the proposed loan over the same period, including all fees and the remaining term. Estimate the break-even period and test different rate scenarios.

Can refinancing lower repayments but cost more overall?

Yes. A longer term can reduce scheduled repayments while increasing total interest. Compare both cash flow and lifetime cost.

Do I need a new property valuation?

Usually the new lender will assess the security, although the method varies. The accepted value can affect the LVR, available product and approval.

What if I am struggling with repayments now?

Contact your lender’s hardship team promptly. Refinancing may not be available or suitable, and delaying can reduce your options. Free financial counselling is available through the National Debt Helpline.

Can I refinance with bad credit?

It may be possible depending on the credit events, recent conduct, equity, serviceability, property and lender policy. Specialist options can cost more, so compare the total cost and the alternative of waiting and improving the position.
