Can I refinance to get a lower interest rate?

If your home loan rate is sitting above what new borrowers are getting, you're probably paying more than you need to.

Refinancing to reduce your rate isn't just about chasing the lowest number on a comparison site. It's about understanding what you're paying now, what's actually available to you based on your equity and income, and whether the switch makes financial sense after you factor in the costs of moving. For Carnegie residents who've been in their homes for a few years and watched property values climb along Dandenong Road and around Koornang Road, this calculation often tilts heavily in favour of making the move.

What Refinancing to a Lower Rate Actually Means

Refinancing for a lower rate means replacing your current home loan with a new one that charges less interest. You're not adding debt or extending your loan term unless you choose to. You're simply paying less interest on the amount you still owe. If you're on a variable rate that hasn't dropped in line with what new customers are being offered, or if your fixed rate expired and rolled to a higher variable rate, you might be paying anywhere from 0.3% to 1% or more above current market rates.

Consider someone who bought a two-bedroom unit near Carnegie station three years ago with a $550,000 loan. They locked in a fixed rate that seemed fine at the time, but when it expired six months ago, they rolled onto their lender's standard variable rate at 6.5%. Meanwhile, new customers at other lenders are getting variable rates closer to 5.8% with the same loan-to-value ratio. On a $480,000 remaining balance, that 0.7% difference costs them around $280 extra each month, or $3,360 a year. If they stay put for another five years without acting, that's over $16,000 in unnecessary interest.

How Much You Could Save by Switching Lenders

The amount you'll save depends on the gap between your current rate and what you can secure elsewhere, your remaining loan balance, and how long you plan to stay in the property. A rate reduction of even half a percent can mean significant savings over time, particularly if you still have a large balance and many years left on your loan.

In our experience, Carnegie homeowners who refinanced after their fixed rate expiry often see monthly repayment reductions between $200 and $400, depending on their loan size. That's money that can go toward offset accounts, renovations, or simply breathing room in the monthly budget. The key is running the numbers properly before you commit. A loan health check gives you a clear picture of where you stand and whether the savings justify the effort.

What It Costs to Refinance and When It's Worth It

Refinancing isn't without cost, and you need to know what you're up against before you start the process. Discharge fees from your current lender typically run between $150 and $400. If you're on a fixed rate and breaking early, the exit costs can be much higher, sometimes thousands of dollars depending on how much time is left and how rates have moved since you locked in. Application fees, valuation costs, and settlement fees from the new lender can add another $600 to $1,200.

The calculation is straightforward: total cost of switching versus total interest savings over the period you plan to stay with the new loan. If you're saving $300 a month and the total cost to refinance is $1,500, you're ahead after five months. If you're planning to sell within a year, the math gets tighter. Most people underestimate how quickly the savings stack up once you're on the other side of the switch. Working with a mortgage broker who can compare lenders without charging you search fees often gets you to the right answer faster than shopping around yourself.

Carnegie's Property Market and Your Refinancing Position

Carnegie's median property values have climbed steadily over the past few years, particularly for well-located units near the station and period homes around the tree-lined streets off Koornang Road. If you bought before the most recent growth cycle, your equity position has likely improved, which directly affects the rate you can access. Lenders price loans based on loan-to-value ratio, and the lower yours is, the sharper the rate you'll be offered.

Someone who bought a three-bedroom Edwardian cottage in Carnegie five years ago for $850,000 and borrowed $680,000 might now own a property worth $1.1 million with a remaining loan balance of $620,000. That drops their LVR from 80% to around 56%, moving them into a pricing tier that unlocks rates typically reserved for borrowers with larger deposits. Refinancing at this point isn't just about rate shopping, it's about leveraging the equity you've built. That same shift in LVR can also open up access to offset accounts and redraw facilities that weren't available on your original loan.

Variable or Fixed: Which Rate Should You Target?

You're not locked into the same rate structure you had before. If you've been on a variable rate and want stability, you can refinance to a fixed rate. If your fixed term just ended and you want flexibility, you can move to a variable product. Each has trade-offs, and the right choice depends on what you value more: certainty or the ability to make extra repayments without penalty.

Variable rates tend to sit slightly below fixed rates right now, and they let you pay off your loan faster if your cashflow allows. Fixed rates lock in your repayment amount for a set period, which can be helpful if you're budgeting tightly or expect your income to change. Split loans, where part of your balance is fixed and part is variable, give you some of both. There's no universal answer, but refinancing is the right moment to reassess what structure actually suits your situation instead of just rolling with what you had.

How Long Refinance Approval Takes and What You'll Need

Once you decide to move forward, the approval process typically takes between two and four weeks, depending on how quickly you can provide documentation and how busy lenders are. You'll need recent payslips, tax returns if you're self-employed, bank statements showing your income and expenses, and proof of identity. Lenders will also revalue your property, either with a desktop assessment or a physical inspection.

If your income or employment situation has changed since you first borrowed, that can affect your borrowing capacity and the rate you're offered. A reduction in income or a switch to contract work doesn't automatically disqualify you, but it does mean you need to present your position clearly and work with someone who knows which lenders are more flexible in that space. Most refinances settle within six weeks from application to final funding, assuming there are no title issues or unexpected valuation surprises.

Refinancing to cut your interest rate is one of the most direct ways to reduce what you're paying without changing your lifestyle or selling your home. If you've been in your Carnegie property for a few years and haven't reviewed your rate recently, the gap between what you're paying and what's available has likely widened.
