Everything You Need to Know About Refinancing & Rates

Can Refinancing Actually Lower Your Interest Rate?

Yes, refinancing can lower your interest rate if you switch to a loan with a lower advertised rate than your current home loan. The interest rate savings depend on the gap between what you're paying now and what's available, as well as how long you hold the new loan.

Consider someone across Melbourne's western suburbs who took out a fixed rate loan at 5.8% three years ago and is now coming off that fixed rate period onto a variable rate above 6%. Refinancing to a lender offering a variable rate around 5.9% with an offset account could reduce monthly repayments and provide access to features their current loan doesn't offer. The actual saving depends on the loan amount, but the monthly difference on a typical Victorian mortgage can be several hundred dollars.

The calculation isn't as direct as comparing two advertised rates. Lenders apply different comparison rates depending on your deposit size, property location, and whether you're switching from fixed to variable or the reverse. Fees for discharging your existing loan, settlement costs, and any break costs if you're exiting a fixed rate early all affect whether the switch delivers a genuine saving over the medium term.

Why Your Current Rate Might Be Higher Than You Think

Your current interest rate might not match what you signed up for originally. Many borrowers locked in fixed rates during the low-rate period and are now reverting to their lender's standard variable rate, which is typically higher than the rates offered to new customers. Lenders often reserve their most competitive rates for new borrowers, leaving existing customers on rates that haven't been reviewed in years.

In our experience, clients who haven't completed a loan health check in the past two years are often paying 0.5% to 1.5% more than they need to. That gap exists because they're still on a rate negotiated years ago or because they've reverted to a default variable rate after their fixed rate expired. A home loan health check compares your current loan structure and rate against what's available now, not just from your current lender but across the entire market.

If you're coming off a fixed rate, your lender may send you a letter outlining your new rate, but they're under no obligation to offer you their lowest available option. That's where a refinance application to another lender can make a tangible difference to your monthly repayments and overall loan costs.

When the Numbers Actually Work in Your Favour

Refinancing makes financial sense when the interest rate reduction is large enough to offset the costs of switching lenders within a reasonable timeframe. Most refinance applications involve discharge fees from your existing lender, application fees with the new lender, and valuation or settlement costs. These can total anywhere from a few hundred to several thousand dollars depending on your loan amount and property location.

A borrower across regional Victoria with a loan amount of around the state median and a rate gap of 0.8% would typically recover refinancing costs within 12 to 18 months through lower monthly repayments. If you plan to hold the loan for at least two years, the switch usually delivers a net saving. If you're planning to sell or pay down the loan significantly within the next 12 months, the upfront costs can outweigh the short-term interest rate benefit.

Another scenario where refinancing delivers clear value is when your fixed rate period is ending and your lender's revert rate sits well above the market. If your current lender offers you a variable rate above 6.2% and another lender is offering 5.9% with an offset account and redraw, the monthly saving on a typical Victorian loan can fund the switching costs within the first year. The key is comparing what you'll actually pay over the next two to three years, not just the headline rate.

What Happens to Your Loan Features When You Switch

Switching lenders to access a lower interest rate often means gaining or losing specific loan features. Some lenders offer offset accounts that reduce the interest charged on your loan balance by offsetting the balance in a linked transaction account. Others provide redraw facilities that let you access extra repayments you've made, but with conditions on how often you can redraw and whether fees apply.

If your current loan doesn't include an offset account and you're regularly keeping savings in a separate account, refinancing to a loan with offset could reduce the interest you're charged each month without requiring you to make extra repayments. On the other hand, if you're switching from a package loan with free redraw and no ongoing fees to a lower-rate loan that charges for redraw or limits access, you need to weigh whether the interest rate saving justifies the change in flexibility.

Some lenders also allow you to split your loan between fixed and variable portions, which can be useful if you want to lock in part of your rate while keeping access to offset on the variable portion. Not all lenders offer this, so if rate certainty and flexible repayments are both priorities, the lender comparison needs to account for structure as much as the advertised rate.

How Break Costs Affect Fixed Rate Refinancing

If you're still within a fixed rate period, exiting that loan early usually triggers break costs. These are calculated based on the difference between your fixed rate and the lender's current cost of funds for the remaining term. If rates have risen since you fixed, break costs are often minimal or zero. If rates have fallen, break costs can run into thousands of dollars.

Before applying to refinance out of a fixed rate loan, ask your current lender for a break cost estimate. This figure changes daily based on wholesale interest rate movements, so the quote is only valid for a short window. Compare that cost against the interest rate saving you'd achieve by switching lenders. If the break cost is several thousand dollars and the rate difference is only 0.3%, it's often worth waiting until the fixed rate period ends unless you're also refinancing to access equity or consolidate other debts.

If your fixed rate is expiring in the next few months, most lenders won't charge break costs once you're within 90 days of the end date. That's often the ideal time to start a refinance application so the new loan settles shortly after your fixed term ends, avoiding both break costs and the revert rate.

Refinancing to Access Equity Alongside a Rate Reduction

Many borrowers refinance not only to lower their interest rate but also to access equity that's built up in their property. This is common when buying an investment property, funding renovations, or consolidating other debts into the mortgage. Releasing equity while refinancing can be done in a single application, but it affects your loan amount and therefore your serviceability assessment.

Lenders assess your ability to service the new loan amount based on your current income, expenses, and other debts. If you're increasing your loan amount to access equity, the lender applies a buffer rate above the actual interest rate to ensure you can still afford repayments if rates rise. This means you might qualify for a lower interest rate on your existing balance but find the equity release portion attracts a slightly different rate or requires additional documentation.

If you're refinancing to access equity for an investment property deposit, some lenders will also assess the rental income from the new property when calculating your borrowing capacity. Structuring the loan correctly at application stage, particularly if you're setting up separate splits for owner-occupied and investment purposes, can affect both your interest rate and your tax position.

How Property Valuation Affects Your Refinance Rate

Your property valuation directly affects the interest rate a lender will offer. Lenders price loans based on loan-to-value ratio, meaning the lower your LVR, the lower your rate. If your property has increased in value since you bought it or you've paid down your loan significantly, your LVR may have dropped enough to qualify for a lower rate band.

Most lenders use desktop or automated valuations for refinance applications unless the property is unusual or in a regional area where recent sales data is limited. If the valuation comes in lower than expected, your LVR increases and you may be offered a higher rate than initially indicated. In some cases, particularly across growth corridors in Melbourne's west like Point Cook, Truganina, and Werribee, property values have shifted enough in recent years that borrowers who purchased several years ago now sit in a much lower LVR band purely due to capital growth.

If the valuation is borderline and you're close to dropping into a lower LVR tier, paying down a small portion of your loan before applying to refinance can sometimes push you into a lower rate bracket. The difference in rate between 80% LVR and 75% LVR, for example, can be 0.2% to 0.4% depending on the lender, which compounds into significant interest rate savings over the life of the loan.

Comparing Refinance Rates Across Lenders

Comparing refinance rates isn't just about finding the lowest advertised figure. Different lenders apply different criteria, and the rate you're offered depends on your deposit, income type, property location, and loan amount. A lender advertising a headline rate of 5.8% might only offer that rate to borrowers with an LVR below 70%, while another lender's 5.9% rate might be available up to 80% LVR with fewer restrictions.

Some lenders also offer ongoing rate discounts for customers who hold other products with them, such as transaction accounts or credit cards. These package discounts can reduce your rate by 0.1% to 0.3%, but they often come with annual package fees that need to be factored into the overall cost. The comparison rate, which includes most fees, gives a clearer picture of what you'll actually pay, but it's based on a standard loan amount and term, so it won't always reflect your specific situation.

Working through a broker lets you compare rates across multiple lenders in a single application process. Rather than applying to several lenders individually, which can affect your credit file, a broker can assess which lenders are likely to offer you the most competitive rate based on your circumstances and submit your application to the one that fits your needs. That includes accounting for features like offset, redraw, and split loan options alongside the interest rate itself.

Call one of our team or book an appointment at a time that works for you to review your current loan and compare what's available across the market. A loan review takes into account your property, your loan amount, and your plans for the next few years so you can see whether refinancing delivers a genuine saving or whether your current rate is already competitive.
