What Not to Refinance Without Checking First

Refinancing to cut your monthly payments works when you check what you're actually gaining against what you might be giving up.

A mortgage refinance can reduce your monthly outgoings by hundreds of dollars, but not every refinance delivers the outcome you're expecting. The difference between a refinance that improves your cashflow and one that costs you more in the long run comes down to understanding exactly what changes when you switch loans.

Consider someone paying $3,200 a month on a variable interest rate who finds a lender offering a lower rate that drops their repayment to $2,850. That's $350 a month back in their pocket, which over a year adds up to $4,200. But if the new loan extends the loan term by five years or removes the offset account they've been using to park $40,000 in savings, the monthly saving might not reflect the actual cost.

We regularly see this when clients come to us after their fixed rate period has ended and they're suddenly paying significantly more each month. The instinct is to find the lowest rate available and move across, but the loan that offers the lowest monthly payment isn't always the one that saves the most money or supports your longer-term plans.

What Changes When You Refinance Your Home Loan

Refinancing replaces your current home loan with a new one, usually with a different lender. The new loan pays out your existing mortgage, and you start making repayments under the new terms. Your monthly payment changes based on the interest rate, loan amount, and remaining loan term.

If you're refinancing to reduce monthly payments, the rate you're moving to matters, but so does the loan structure. Extending your loan term from 25 years remaining to 30 years will lower your monthly repayment even if the interest rate stays the same, but you'll pay more interest overall. Shifting from a variable interest rate to a fixed interest rate can lock in predictable repayments, but you lose the flexibility to make extra repayments without penalty on most fixed loan products.

The refinance process typically takes two to four weeks once you've submitted your refinance application, depending on how quickly the property valuation is completed and how responsive your current lender is with the discharge process. During that time, your current loan continues as normal.

Why Your Loan Amount Matters More Than the Rate Alone

Your loan amount directly affects how much you'll save by accessing a lower interest rate. A 0.5% rate reduction on a $400,000 loan saves around $170 a month. The same rate reduction on a $600,000 loan saves closer to $255 a month.

If you're releasing equity as part of the refinance, your loan amount increases, which means your repayment might not drop as much as you expect even with a lower rate. Accessing equity for investment purposes or to consolidate debt into your mortgage can improve cashflow in other areas, but it's worth running the numbers to see whether the overall repayment still gives you the breathing room you're after.

In our experience, clients who consolidate personal loans or car debt into their mortgage often see a significant drop in total monthly commitments, even if the home loan repayment itself doesn't fall dramatically. The key is understanding where the cashflow improvement is actually coming from.

Fixed Rate Periods Ending and What Happens Next

When your fixed rate period ends, your loan typically reverts to the lender's standard variable rate, which is almost always higher than the rate you were locked into. If your monthly repayment jumps from $2,400 to $3,100 overnight, refinancing to a lower rate elsewhere can bring that repayment back down to something closer to what you were paying, or even lower.

But not every lender's variable interest rate is the same, and the features attached to the loan vary. Some variable loans come with a refinance offset account, which reduces the interest you're charged without requiring you to pay down the loan directly. Others offer redraw facilities that let you access extra repayments you've made, but with conditions around how quickly you can withdraw and whether fees apply.

If you're coming off a fixed rate and want to lock in certainty again, switching to another fixed interest rate can stabilise your repayments, but you'll need to weigh that against the likelihood of rates falling further and whether you want the option to make extra repayments. A loan health check before your fixed rate expires gives you time to compare what's available and move across without the pressure of a sudden repayment increase.

When Refinancing to a Lower Rate Still Costs You

Refinancing to access a better interest rate doesn't always mean you'll pay less overall. If your current loan has 22 years remaining and you refinance to a 30-year term, your monthly repayment drops, but you're paying interest for an extra eight years. On a $500,000 loan, that can add tens of thousands of dollars in interest charges, even at a lower rate.

Some lenders also charge higher upfront fees for refinance applications, including valuation fees, application fees, and settlement costs. If those fees are capitalised into the loan amount rather than paid upfront, they increase what you owe and reduce the impact of the rate saving.

You also need to check whether your current lender charges exit fees or break costs if you're still within a fixed rate period. Break costs can run into the thousands of dollars if you're leaving a fixed loan early, and in some cases they'll wipe out the first year or two of savings from the new loan. Our role is to calculate whether the switch still makes sense once those costs are factored in, or whether you're ahead by staying put and waiting until the fixed rate expiry date.

What to Check Before You Submit a Refinance Application

Before you move ahead with a mortgage refinance, check what features you're currently using and whether the new loan offers the same functionality. If you've been making extra repayments into a redraw facility or using an offset account to reduce interest, losing that feature might cost you more than the rate saving delivers.

Check the loan term on the new loan and whether it resets to 30 years or matches your remaining term. If you want to keep your loan on the same timeline, ask the lender to match the remaining term so you're not extending how long you'll be paying off the property.

Check the comparison rate, which includes most fees and gives you a closer picture of the true cost of the loan. A loan with a lower advertised rate but higher ongoing fees can end up costing more than a loan with a slightly higher rate and lower fees.

Finally, check whether the lender will require a new property valuation and what happens if the valuation comes in lower than expected. If you're relying on a certain amount of equity to make the refinance work, a low valuation can derail the application or force you to accept a smaller loan amount.

How Refinancing Improves Cashflow Without Extending Your Loan

If reducing your monthly payment is the goal but you don't want to add years to your mortgage, you can refinance to a lower rate and keep the same loan term. The repayment drops because of the rate, not because you're stretching out the loan.

As an example, someone with 23 years remaining on a $450,000 loan at a variable interest rate could refinance to a loan with the same 23-year term but a rate that's 0.6% lower. The monthly repayment falls by around $200, and the loan is still paid off at the same time. Over the remaining term, that rate difference saves a significant amount in interest without requiring any change to the repayment schedule.

If you want to go further, you can keep making the same repayment you were making before the refinance, but direct the extra amount into an offset account or as additional repayments. That way you're not locked into a higher repayment, but you're still reducing the interest and paying the loan down faster when cashflow allows.

Refinancing in Queensland and What Local Clients Should Know

Queensland property owners refinancing their home loan go through the same refinance process as clients in other states, but there are a few local factors worth noting. Queensland doesn't charge stamp duty on mortgage refinancing, which removes one cost that can apply in other circumstances.

Property valuations in regional Queensland can sometimes take longer to arrange than in Brisbane or the Gold Coast, which can add a week or two to the refinance timeline. If you're refinancing a property in a smaller town or rural area, it's worth factoring in that delay when planning your switch.

For clients with investment properties in high-demand Queensland markets, a recent valuation might show equity growth that opens up options for accessing equity or negotiating a lower rate based on a reduced loan-to-value ratio. If you purchased a few years ago and the property has increased in value, that equity can work in your favour when you apply to refinance your mortgage.
