Top tips to refinance and cut your interest rate

Switching to a lower interest rate through refinancing can put hundreds of dollars back in your pocket each month.

For homeowners in Merrylands, refinancing to reduce your rate is one of the most direct ways to build equity faster and free up cash flow. The suburb has seen steady property value growth over recent years, which means many locals are sitting on usable equity but still paying rates that were competitive two or three years ago but no longer reflect what's available today. If your current interest rate sits above what newer borrowers are getting, you're effectively handing money to your lender that could be working for you elsewhere.

Why your current rate probably isn't the sharpest anymore

Lenders typically reserve their most competitive rates for new customers, leaving existing borrowers on higher margins unless they actively push back. If you took out your home loan more than 12 to 18 months ago and haven't reviewed it since, there's a strong chance you're paying more than you need to. This is especially true if you were locked into a fixed rate that's now reverted to a standard variable rate, which often carries a higher margin than what the same lender offers to new applicants.

Consider a homeowner in Merrylands who locked in a fixed rate a few years back when rates were climbing. That fixed period has now ended, and they've rolled onto a variable rate sitting around 6.5%. Meanwhile, competitive variable rates for owner-occupiers with principal and interest repayments are hovering closer to 5.9% to 6.2%, depending on the lender and loan-to-value ratio. On a loan balance of $450,000, even a 0.4% reduction translates to roughly $150 less in monthly repayments. Over a year, that's $1,800 staying in your offset account or going toward extra repayments instead of interest.

How to work out what you could actually save

The difference between your current rate and what you could refinance to is the starting point, but the real savings depend on your loan balance, remaining loan term, and how you structure the new loan. A rate reduction matters most when your loan balance is still substantial, because that's when every fraction of a percentage point compounds over time.

If you're currently paying 6.3% on a $500,000 balance with 25 years remaining, dropping to 5.9% would reduce your monthly repayment by around $130. That might not sound like a fortune, but it's $130 that either reduces your principal faster or builds a buffer in your offset. The interest savings over the life of the loan add up, but the immediate impact on cash flow is what most people in Merrylands notice first, especially if they're managing a household budget alongside rising costs elsewhere.

You can run the numbers yourself, but a loan health check gives you a clearer picture of what's available based on your actual loan structure, equity position, and repayment history. It's worth doing before you assume your current lender is still the right fit.

What actually costs money when you refinance

Refinancing isn't completely without expense, and you need to know what you're paying upfront to make sure the rate reduction justifies the move. Discharge fees from your current lender typically sit between $300 and $500. Application fees with the new lender can range from zero to around $600, depending on the product and whether the lender is running a promotion. Valuation fees are sometimes waived, but when they're not, expect $200 to $300. Government fees for registration and discharge in New South Wales usually add another $150 to $200.

If you're coming out of a fixed rate early, break costs can be significant. These are calculated based on the difference between your fixed rate and the current wholesale rate, plus the time left on your fixed term. If rates have dropped since you fixed, break costs can run into thousands of dollars. If rates have risen, break costs might be minimal or even zero. Don't assume anything until your current lender gives you a written break cost figure.

In most cases, if you're switching for a rate reduction of 0.3% or more and your loan balance is above $300,000, the upfront costs are recovered within the first 12 to 18 months through lower repayments. But if your loan balance is small or you're planning to sell within the next two years, refinancing might not deliver enough value to justify the hassle.

The comparison rate trap that catches people out

Advertised interest rates can look sharp on paper, but the comparison rate is what tells you the true cost once fees are rolled in. A lender might promote a headline rate of 5.89%, but if the comparison rate is 6.15%, that gap reflects ongoing fees, annual charges, or a higher rate after an introductory period ends.

Comparison rates are calculated on a $150,000 loan over 25 years, which doesn't always reflect your situation. If your loan balance is $600,000 or you've only got 15 years left on your mortgage, the impact of annual fees becomes proportionally smaller or larger. A $395 annual fee matters less on a $700,000 loan than it does on a $200,000 one, so don't rely on comparison rates alone to compare products. Look at the actual interest rate, the fee structure, and how those combine based on your specific loan size and term.

When switching lenders makes sense versus staying put

Sometimes your current lender will drop your rate if you ask, especially if you've been a reliable borrower with a decent amount of equity. This is called a retention offer, and it can save you the time and cost of a full refinance. The catch is that retention offers are rarely as sharp as what the lender is offering new customers, and they're often temporary. You might get a 0.2% discount for 12 months, but unless it's locked in for longer, you'll be back in the same position next year.

Switching lenders gives you access to the sharpest rates and lets you reset your loan structure entirely. If your current lender won't budge or only offers a token reduction, moving to a new lender is usually the right call. You also get the chance to renegotiate features like offset accounts, redraw flexibility, and repayment options that might not have been available or prioritised when you first borrowed.

For Merrylands homeowners who've built up equity and improved their financial position since they first bought, switching lenders can also unlock lower loan-to-value pricing. If you started with a 90% LVR and you're now sitting at 70% or below, the rate you qualify for will reflect that lower risk.

How a broker handles the process differently than going direct

Applying directly to a lender means you're limited to whatever that lender offers, and you're doing the legwork yourself to compare products, submit documents, and follow up on approvals. A mortgage broker compares rates and features across multiple lenders, identifies which ones are likely to approve your application based on your income and credit profile, and manages the paperwork on your behalf.

Brokers also have access to rate discounts and product variations that aren't advertised publicly. Some lenders only work through brokers, so going direct means you're not even seeing the full market. If your income structure is slightly unusual or you've got a mix of PAYG and self-employed income, a broker knows which lenders assess those scenarios more favourably, which speeds up approval and reduces the chance of a decline.

For anyone refinancing in Merrylands, working with a local broker who understands the area and the types of properties that sit well with different lenders removes a lot of the guesswork. You're not trying to decode policy documents or second-guess whether your application will get knocked back halfway through.

What happens to your repayments when the rate drops

When you refinance to a lower rate, your minimum monthly repayment will drop unless you deliberately keep it at the same level. If you were paying $3,200 a month and your new repayment is $3,050, you can either pocket that $150 or keep paying $3,200 and clear your loan faster. The second option is how people use rate reductions to build wealth rather than just ease cash flow.

Keeping your repayment the same after refinancing means the extra amount goes straight onto your principal, which cuts years off your loan term and reduces the total interest you'll pay. If you've refinanced to a loan with an offset account, you could also redirect that $150 into the offset each month, which has the same effect on interest while keeping the cash accessible if you need it.

Some people in Merrylands refinance specifically to reduce monthly repayments so they can redirect that cash flow into an investment property deposit, a renovation, or paying down other debt. Both approaches work, but you need to decide upfront whether you're refinancing for breathing room or to accelerate equity growth. If it's the latter, set your repayment amount manually and don't let it drop just because the minimum has changed.

Fixed versus variable when you're chasing a rate cut

If you're refinancing to reduce your rate right now, you'll need to decide whether to lock in a fixed rate or move to a variable product. Fixed rates give you certainty, but they also lock you into that rate even if the market drops further. Variable rates move with the market, which means you benefit if rates fall but you're exposed if they rise again.

At the time of writing, variable rates are often sharper than fixed rates for owner-occupiers, which is the opposite of what was happening a couple of years ago. If your priority is locking in the lowest rate available today, variable is likely the better option. If you want predictable repayments and you're comfortable with the current fixed rate offerings, a fixed term of two or three years can make sense, especially if you think rates have bottomed out.

You can also split your loan between fixed and variable, which gives you some rate protection while still leaving part of your loan flexible. This works well if you want to make extra repayments without hitting fixed rate restrictions, but you still want a portion of your repayment locked in. Talk through the trade-offs with someone who can show you the numbers side by side rather than guessing which structure will age well.
