When to Refinance & How Much You Can Save

Refinancing becomes worthwhile when the rate reduction exceeds the cost of switching, typically at least 0.30% lower than your current rate, or when product features no longer match your circumstances.

Most Grange property owners sit on loans that were appropriate at settlement but have drifted away from current market pricing or their evolving needs. The question is whether moving lenders delivers enough benefit to justify the application process, valuation costs, and discharge fees. The answer depends on three factors: the rate differential, the loan balance remaining, and how long you intend to hold the property.

Calculating Whether the Rate Reduction Justifies the Cost

The saving from a lower interest rate compounds over time, so larger loan balances and longer hold periods amplify the benefit. On a loan balance of $500,000, a 0.40% rate reduction saves around $2,000 in the first year. If refinancing costs $1,200 in valuation and discharge fees, you recover that outlay within eight months and continue saving thereafter.

If your loan balance sits below $300,000 or you plan to sell within two years, the absolute saving shrinks and may not cover the switching cost. Run the numbers with your current rate, the rate you can access elsewhere, your remaining loan balance, and the fees involved. If the break-even point falls within the first 12 months, refinancing usually makes sense.

Coming Off a Fixed Rate Period Without a Plan

When a fixed rate period ends, most lenders revert borrowers to their standard variable rate, which often sits 0.50% to 0.80% higher than the discounted rates offered to new customers. If your fixed rate is expiring within the next 90 days, now is the time to compare what your current lender offers for retention against what you can access by switching.

Consider a Grange homeowner who fixed at 2.19% three years ago on a loan balance of $650,000. That rate expires next month, and the lender's reversion rate is 6.49%. A discounted variable rate elsewhere might be 5.89%. The difference is $3,900 in the first year. Waiting until after the fixed period ends to start the refinancing process means paying the higher reversion rate during the assessment period, which typically takes four to six weeks.

Accessing Equity Without Selling

Refinancing allows you to access equity that has accumulated through price growth or principal repayment without selling the property. This suits Grange owners looking to fund a deposit on an investment property, renovate, or consolidate other debts.

Lenders typically allow you to borrow up to 80% of the property's current value without incurring lender's mortgage insurance. If your property was purchased for $800,000 and is now valued at $950,000, and your remaining loan balance is $600,000, you could access up to $160,000 in equity at that threshold. The refinanced loan becomes $760,000, and the funds are available at mortgage rates rather than personal loan or credit card rates.

Equity release only makes financial sense when the purpose generates a return or replaces higher-cost debt. Using it to fund lifestyle spending adds to your loan balance without delivering a corresponding benefit. Structure it carefully, and consider splitting the loan so the portion used for investment remains separately identifiable for tax purposes.

Product Features That No Longer Suit Your Situation

Rate is not the only reason to move. Offset accounts, redraw facilities, and repayment flexibility vary significantly across lenders. If your current loan lacks an offset account and you maintain a buffer of $40,000 in savings, you are paying interest on that amount unnecessarily. Switching to a loan with a full offset saves interest equivalent to your mortgage rate on the offset balance.

Some lenders restrict additional repayments or charge for redraw access. Others cap offset balances or apply offsets only partially. If your income has increased or your financial situation has changed since you first borrowed, the product that suited you then may now be costing you more than it should. A loan health check identifies whether your current structure still aligns with how you manage money.

When Refinancing Costs More Than It Saves

Refinancing does not always deliver a net benefit. If you are within two years of paying off the loan, the interest saving over that short period may not cover the switching costs. Similarly, if you have a heavily discounted rate due to a package or employer arrangement, the rate available elsewhere may not be lower enough to justify the move.

Break costs on a fixed rate loan can also eliminate any saving. If you are midway through a fixed term and rates have fallen since you locked in, the lender calculates a break cost based on the difference between your fixed rate and the current wholesale cost of funding. That cost can run into tens of thousands of dollars on large loan balances. Always request a break cost estimate before assuming refinancing will save money.

Consolidating Debts Into Your Mortgage

If you carry personal loans, car loans, or credit card balances at rates above 8%, consolidating those debts into your mortgage reduces the interest rate and can improve cashflow. A $30,000 car loan at 9% and a $15,000 credit card balance at 18% cost around $5,400 per year in interest. Consolidating both into a mortgage at 6% reduces that to $2,700.

The downside is that you extend the repayment term from a few years to the remaining life of your mortgage, which increases the total interest paid unless you maintain the same repayment level. Structure the consolidation as a split loan and continue paying what you were paying on the original debts. That clears the consolidated portion faster and avoids turning short-term debt into a 30-year commitment.

Timing the Application to Match Your Property Plans

If you intend to sell your Grange property within 12 months, refinancing rarely makes sense unless you plan to port the loan to your next property. The upfront costs consume most of the short-term saving, and you will need to discharge the new loan shortly after settling it.

If you are planning a renovation or subdivision, refinance before starting the work. Lenders assess your borrowing capacity based on your current income and existing debts, and construction lending often requires a different assessment process. Securing a refinance with equity access while the property is in its current state simplifies the approval and avoids complications from incomplete building work affecting valuation.

Using a Broker to Compare More Than Rate

Lenders price loans differently depending on loan-to-value ratio, property type, and borrower profile. A rate advertised online may not be the rate you can access, and product features vary in ways that are not immediately obvious from a comparison table. Some lenders offer lower rates but charge higher ongoing fees, while others include offset accounts only on premium products.

A mortgage broker in Grange compares not just the rate but the structure, fees, and features across multiple lenders and matches them to your specific situation. That comparison identifies whether switching delivers a genuine benefit or whether negotiating a retention offer with your current lender achieves the same outcome with less effort.
