Common Mistakes When Refinancing for Lower Rates

Refinancing your mortgage to access a lower interest rate can reduce your monthly repayments and the total cost of your loan over time. The decision to refinance depends on the rate difference between your current loan and what's available, the costs involved in switching, and how long you plan to keep the new loan.

Many Kew homeowners refinance when their fixed rate period ends and they're automatically moved to a higher revert rate. Others refinance because their existing lender hasn't adjusted their rate in line with market movements, leaving them on a rate that no longer reflects what's available to new borrowers.

How Much Rate Difference Justifies Refinancing

A rate reduction of 0.50% or more typically justifies the cost and effort of refinancing, though the exact threshold depends on your loan amount and how much you'll pay in discharge and application fees. Consider a borrower in Kew with a $600,000 loan balance who refinances from a 6.20% variable rate to a 5.60% rate. The monthly repayment would drop by approximately $230, which over a year represents $2,760 in savings. If refinancing costs total $1,500 in discharge, application, and valuation fees, the borrower recovers those costs in under seven months and continues to save beyond that point.

The calculation changes if you're only a few years into a 30-year loan term versus nearing the end of your mortgage. A larger loan balance amplifies the benefit of even a modest rate reduction, while a smaller remaining balance may not generate enough savings to offset the switching costs.

Fixed Rate Expiry and Revert Rates

When a fixed rate period ends, your loan typically reverts to your lender's standard variable rate, which is often 1.00% to 1.50% higher than the rates offered to new customers. This revert rate is where many borrowers find themselves paying more than necessary. If your fixed rate is expiring soon, you have three options: negotiate with your current lender for a lower rate, switch to a different product with the same lender, or refinance to a new lender.

Some lenders will reduce your rate if you request it, particularly if you have a solid repayment history and equity in your property. Others hold firm on their pricing, especially if they're not actively competing for refinance business. In those cases, switching lenders becomes the only way to access current market rates. The application process for refinancing is similar to applying for a new loan, which means you'll need to provide income verification, undergo a credit assessment, and have your property revalued.

Comparing Loan Features Beyond the Interest Rate

The advertised rate is not the only factor that determines whether a refinance makes sense. Loan features such as offset accounts, redraw facilities, and the ability to make extra repayments without penalty all affect how a loan performs for your circumstances. An offset account links to your loan and reduces the interest charged on the balance by the amount held in the account. If you maintain a balance of $20,000 in an offset account against a $500,000 loan, you only pay interest on $480,000.

Some low-rate loans exclude offset accounts or charge a higher fee to include one. If you regularly hold surplus funds that could sit in an offset, a slightly higher rate with full offset functionality may deliver more value than a lower rate without it. Redraw facilities allow you to access extra repayments you've made, but some lenders restrict how often you can redraw or charge fees for doing so. If you're refinancing to access equity or plan to make lump sum payments, confirm the loan structure supports that without penalties.

Application Costs and Settlement Timeline

Refinancing involves several upfront costs that reduce the net benefit of a lower rate. Discharge fees from your current lender typically range from $300 to $500. The new lender may charge an application fee of $600 to $800, though some lenders waive this for refinance customers. A property valuation is required in most cases, which costs between $200 and $400 depending on the property type and location. In Kew, where property values are higher than many outer suburbs, lenders may request a full valuation rather than relying on automated estimates.

Settlement takes four to six weeks on average, though delays can occur if the property valuation comes in below the lender's expectation or if there are complications with the title. During this period, you continue paying your existing loan. Some borrowers time their refinance to coincide with their current loan's redraw or offset balance so they can transfer those funds into the new loan structure immediately after settlement.

When Refinancing Doesn't Make Sense

Refinancing is not always the right move, even when a lower rate is available. If you plan to sell your property within the next 12 to 18 months, the time and cost of refinancing may exceed the savings you'd achieve. Similarly, if your loan balance is below $200,000 and the rate difference is modest, the dollar value of the savings may not justify the administrative effort.

Borrowers who have recently changed employment or become self-employed may find it harder to refinance because lenders require stable income evidence. If your financial situation has changed since you first borrowed, it's worth reviewing your borrowing capacity before starting the refinance process. Some borrowers also overlook the exit fees or break costs on their current loan, particularly if they're still within a fixed rate period. Breaking a fixed rate early can result in costs that eliminate any benefit from refinancing.

Refinancing to Consolidate Debt or Access Equity

Some Kew homeowners refinance not only to reduce their rate but also to consolidate other debts or access equity for investment purposes. Consolidating personal loans or credit card debt into your mortgage can reduce your overall interest cost, as mortgage rates are typically lower than unsecured lending rates. The trade-off is that you're converting short-term debt into a loan secured against your property with a longer repayment period.

Accessing equity through refinancing allows you to borrow against the value you've built in your property without selling it. This is common among property investors who want to use equity from one property as a deposit for another. The amount you can access depends on the lender's loan-to-value ratio requirements and your ability to service the higher loan amount. A loan health check can clarify how much equity you have and whether your current loan structure is competitive before you move forward with a refinance.

Switching Between Variable and Fixed Rates

Refinancing also provides an opportunity to switch between variable and fixed interest rates depending on your outlook and risk tolerance. Variable rates fluctuate with market conditions, which means your repayments can increase or decrease over time. Fixed rates lock in your repayment amount for a set period, typically one to five years, which provides certainty but removes the benefit if variable rates fall during that period.

If you're coming off a fixed rate and expect rates to remain stable or decline, moving to a variable loan with a competitive rate and offset account may offer more flexibility. If you prefer repayment certainty and believe rates will rise, fixing part or all of your loan can protect you from future increases. Some borrowers split their loan between fixed and variable portions to balance certainty with flexibility. Your decision should reflect your financial goals, cash flow requirements, and how long you plan to hold the property.

Refinancing to a lower rate is one of the most direct ways to reduce the cost of your mortgage, but the decision involves more than comparing advertised rates. The right loan structure depends on your property, your income, and how you use your mortgage as part of your broader financial position.
