Should You Consolidate Debt Into Your Home Loan? What Australian Borrowers Need to Know
Credit cards, car loans and personal loans are getting more expensive to carry, and the RBA lifted the cash rate to 4.60% in September. Many Australians are now asking whether they should roll those debts into their home loan to cut the monthly squeeze.
Is putting your debts into your mortgage actually a good idea?
What debt consolidation into a home loan means
Debt consolidation means borrowing extra against your home, or refinancing to a bigger loan, and using the money to pay out other debts. Those debts then sit inside your mortgage.
Common debts people consolidate:
Credit cards
Personal loans
Car loans
Buy now pay later balances
Store cards and tax debts
The appeal is simple. A home loan rate is usually far lower than a credit card rate or a personal loan rate. One repayment replaces several, and your monthly cash flow often improves straight away.
Why the interest rate looks so good
Credit card rates often sit above 20%. Personal loans commonly sit well into the double digits. Home loan rates, even after recent rises, are a fraction of that.
Moving a $20,000 credit card balance from a rate near 20% to a home loan rate near 6% sounds like an easy win. And on paper, the interest saving is real.
But the rate is only half the story.
The catch: you pay it off over 30 years
This is where consolidation can go wrong. A car loan with three years left might cost you a few thousand dollars in interest. Move it into a 30 year mortgage and you pay interest on it for decades.
Here is a simple way to think about it:
Lower repayment now does not mean cheaper overall
A longer term means more total interest, even at a lower rate
Short debts turned into long debts can cost more in the end
If you consolidate, the smart move is to keep paying the extra amount as if it were still a separate loan. That way you get the lower rate without stretching the debt out.
Ways to consolidate debt through your mortgage
There is more than one route. The right one depends on your equity and your lender.
Refinance to a larger loan. You switch lenders, borrow more and pay out the debts at settlement. This can also let you pick up a sharper rate.
Top up your existing loan. Your current lender increases your limit. Quick, but you may stay on a higher rate.
Use a separate split. Put the consolidated debt in its own loan split so you can track it and pay it down faster.
Draw on an offset or redraw. If you have built up a buffer, using it may beat borrowing more.
Each option is assessed as new lending, so your lender will check your income, expenses and credit file again.
Will a lender approve it?
Lenders look at the same things as any home loan application. They want to see that you can afford the new, larger repayment under a higher test rate.
They will look at:
Your income and how stable it is
Your living expenses and spending patterns
Your equity, usually keeping your loan under 80% of your property's value to avoid LMI
Your credit history, including missed or late payments
Lenders also check why you are consolidating. If your statements show ongoing overspending, expect questions. Consolidation works best when it fixes a cost problem, not a spending habit.
Your borrowing power matters too. Closing a credit card limit before applying can help, because lenders count the full limit as a debt even if the balance is zero. Our guide on How to Increase Your Borrowing Capacity for a Home Loan in Australia explains how this works.
The risk of using your home to pay unsecured debt
Credit card debt and personal loans are unsecured. If you fall behind, the lender cannot take your house. Once that debt sits in your mortgage, it is secured against your home.
That is a real trade-off. If rates keep rising or your income drops, a missed repayment now puts your property at risk, not just your credit score.
Other risks to weigh:
Fees, such as discharge fees, application fees and valuation costs
Lenders Mortgage Insurance if you borrow above 80% of your property's value
Running the cards back up after paying them off, which leaves you with the mortgage debt and new card debt
If you cancel or lower the card limits when you consolidate, you protect yourself from the last one.
When consolidation makes sense
It often works well when:
You have high interest debts and real equity in your home
You can keep repaying at the old repayment level, or close to it
You have fixed the spending issue that caused the debt
Your current mortgage rate is competitive, or a refinance would improve it
It is a poor fit when the debts are nearly paid off, when you have little equity, or when you would only be moving the problem to a longer timeframe.
Alternatives to consider first
Before you add to your mortgage, ask whether another option fits better.
Call your lender and ask for a rate cut. A lower rate eases the pressure without new borrowing. See How to Negotiate a Lower Interest Rate on Your Home Loan.
Pay off the highest rate debt first, using any savings or offset balance.
Ask your card provider for a balance transfer offer or a hardship arrangement.
Check whether you are already feeling the pinch of rising repayments. Our guide to Mortgage Stress in Australia: What It Means and What You Can Do covers the warning signs.
If you are struggling to meet repayments, speak to your lender about hardship options early. They have more flexibility the sooner you ask.
How a broker can help
Consolidation is not one size fits all. A broker can compare lenders on policy, not just rate, because some treat top ups and cash out borrowing very differently. We can also model what you would pay in total interest, so you see the real cost over time rather than only the lower monthly figure.
We will tell you straight if consolidating is not the right move for you.
