What Not to Refinance For and Why It Matters

Refinancing often gets promoted as a cure-all for any mortgage problem. It can deliver genuine value when applied to the right situation, but it can also cost you thousands if you refinance for the wrong reason or at the wrong time.

The most dependable reason to refinance is to reduce your interest rate when lenders have dropped their rates or your current lender no longer offers competitive terms. That said, not every rate drop is worth acting on, and several other commonly marketed refinancing benefits either fail to stack up financially or create problems down the line.

Refinancing to Access Equity Without a Specific Purpose

Releasing equity from your property to fund an investment, renovation, or debt consolidation can be a sound financial move if the purpose is income-generating or reduces higher-interest debt. Refinancing to access equity for investment works when the funds go toward an asset that will grow or generate rental income. If the equity is being withdrawn without a defined purpose or to fund lifestyle spending, you are increasing your loan amount and extending the time it will take to own your home outright.

In our experience with ADF members posted to RAAF Base Pearce or Campbell Barracks, equity release works when it is part of a broader plan, such as purchasing a second property before a posting or funding a renovation that increases the home's resale value. Withdrawing equity to cover general expenses or holidays means you are borrowing against your future to fund your present, and that debt carries interest every month until it is repaid.

Consolidating Debt That Will Reappear

Consolidating credit card debt or personal loans into your mortgage can reduce your monthly repayments and lower your overall interest rate, but only if the behaviour that created the debt has changed. If you consolidate a $15,000 credit card balance into your mortgage and then rebuild that credit card debt over the next two years, you now have both the consolidated debt on your mortgage and a new balance on the card.

The monthly cashflow improvement from debt consolidation is real, and the interest rate on a mortgage is far lower than a credit card or car loan. The problem is not the consolidation itself but the assumption that refinancing solves the underlying spending or budgeting issue. If you are considering refinancing to consolidate debt, work out what will change after the refinance to prevent the debt from returning. If nothing changes, the refinance simply delays the problem and makes it larger.

Switching From Variable to Fixed Because Rates Might Rise

Locking in a fixed rate because you are worried about future rate increases can provide certainty, but it can also leave you stuck on a higher rate if variable rates drop or remain flat. Fixed rates are typically priced above current variable rates because lenders factor in the risk of rate movements over the fixed period. If you lock in a fixed rate and rates do not rise as much as expected, you will pay more interest than you would have on a variable loan.

Consider a member refinancing a $500,000 loan in Perth and choosing a three-year fixed rate to avoid potential increases. If variable rates remain steady or drop during that fixed period, the member is paying more than necessary and cannot access offset accounts or make extra repayments without hitting strict limits. When the fixed rate period ends, the loan reverts to a variable rate anyway, so the protection is temporary. Fixed rates work when you need payment certainty for budgeting, not as a hedge against uncertain rate movements.

Refinancing to a Lender With One Attractive Feature but Poor Overall Terms

A lender might advertise a loan with an offset account, redraw facility, or rate discount that looks appealing in isolation, but the overall loan structure could cost you more than your current arrangement. An offset account only delivers value if you maintain a balance in it. A redraw facility is useful if you make extra repayments, but if the loan's base rate is higher than what you currently pay, the feature does not compensate for the additional interest.

Before refinancing based on a single product feature, compare the total cost over the life of the loan. If your current loan is at a lower rate and you rarely use redraw or offset, switching to a loan with a higher rate just to access those features will cost more than it saves. ADF members in WA often have access to loans with no lender's mortgage insurance, which can offset other features. Do not give up that benefit unless the new loan delivers measurable savings.

Refinancing Too Soon After Your Last Refinance or Purchase

Each time you refinance, you pay discharge fees to your current lender, application fees to the new lender, and potentially valuation or legal costs. If you refinance within 12 to 18 months of your last refinance or purchase, those costs may exceed any interest savings you achieve. The break-even point on a refinance typically sits between 12 and 24 months, depending on the fees and the rate reduction.

If you refinanced recently and rates have dropped further, calculate whether the interest saving over the remaining loan term justifies the upfront costs. If your current loan already includes an offset account or allows unlimited extra repayments, you might achieve a similar outcome by increasing your repayments rather than refinancing again. A loan health check can clarify whether refinancing now makes financial sense or whether waiting another year will deliver a stronger outcome.

Refinancing Without Comparing Total Loan Costs

A lower advertised rate does not always mean a lower total cost. Some lenders offset a low rate with higher fees, limited features, or restrictions on extra repayments. Others offer a discounted rate for the first year, then revert to a higher standard rate. If you refinance based on the headline rate without reviewing the comparison rate, ongoing fees, or revert rate, you may end up paying more over the loan term.

When comparing refinance options, look at the comparison rate, which includes most fees and charges. Check whether the rate is fixed for a set period or subject to change. Confirm whether offset, redraw, and extra repayments are available without restrictions. ADF members in WA should also confirm whether the lender applies the no-LMI policy consistently across refinances, as some lenders limit this benefit to new purchases. If you are unsure which loan structure suits your situation, speaking with a broker who understands ADF-specific loan features will save you from refinancing into a product that costs more than your current loan.

Refinancing works when the reason is clear, the numbers support it, and the new loan aligns with your financial priorities. If the primary motivation is a vague sense that you should be doing something or a single feature that looks attractive without examining the full cost, wait until the case for refinancing is stronger.
