If you’re juggling a personal loan, a credit card and maybe a car repayment on top of your mortgage, rolling everything into one home loan payment can sound appealing. A debt consolidation home loan is one of the most common strategies Perth homeowners look into, and it’s easy to see why. It’s also not a one-size-fits-all solution.
This isn’t about general debt consolidation, the kind you’d look at with a personal loan or a balance transfer. This guide is specifically about using the equity in your home, through a refinance or loan increase, to consolidate other debts. Understanding the benefits and the trade-offs before you do it can help you make a more informed decision and avoid a costly mismatch.
A debt consolidation home loan works by increasing your existing mortgage, or refinancing to a new one, to pay out other debts. This can include credit cards, personal loans or car loans. The result is a single monthly repayment, often at a lower interest rate than what you were paying across those separate debts, depending on your lender, credit profile and market conditions.
A home loan typically runs over 25 to 30 years. Spreading short-term debt over that timeframe can lower your monthly repayments, but it can also increase the total interest paid over the life of the loan. Whether it makes sense depends on your equity position, the interest rates on your existing debts, and how much of that longer-term cost you’re comfortable taking on. This is not right for everyone, and it is a decision worth modelling properly rather than judging on the headline rate alone.
How a Debt Consolidation Home Loan Works
When you consolidate debt into your mortgage, you’re increasing your home loan balance to pay out other debts. Your current lender, or a new one if you refinance, rolls those balances, credit cards, personal loans, buy-now-pay-later accounts, into your home loan.
The result is one monthly repayment, at what may be a lower rate than you were paying across your various debts. Instead of tracking several due dates with several lenders, you have one payment and one lender.
A mortgage broker can assess whether your current lender offers a competitive option, or whether switching lenders gives you better terms for consolidating debt into your home loan.
Why Homeowners Consider It
A debt consolidation home loan can attract attention for a few reasons:
- Lower interest rate. Credit cards and personal loans generally carry higher interest rates than home loans, though exact rates depend on your lender, your credit profile and market conditions at the time. MoneySmart’s guide to debt consolidation and refinancing has more on how this comparison typically plays out.
- Simplified finances. One payment replaces several. For homeowners feeling stretched managing multiple debts, this alone can reduce financial stress.
- Improved monthly cash flow. Rolling higher-rate debts into a lower-rate mortgage may reduce total monthly outgoings, freeing up cash each month, but it can increase the total interest paid over the life of the home loan.
For some borrowers, refinancing to pay off debt in one move may improve their financial position. The full picture is more nuanced than the headline rate suggests.
The Trade-Offs You Need to Understand
A lower interest rate doesn’t always mean you pay less overall, and this is where many borrowers are caught off guard.
When you consolidate short-term debt into a 25 or 30-year mortgage, that debt is stretched over decades. Even at a lower rate, the total interest paid over the life of the loan can end up higher. That’s because the original debts would have been cleared in a much shorter timeframe.
There’s also the shift from unsecured to secured debt to consider. Credit cards and personal loans are unsecured, meaning a lender can’t automatically claim your home if you fall behind. Once those debts are rolled into your mortgage, they become secured against your property. That’s a meaningful change in risk.
Other things to factor in:
- Discharge and refinancing fees from your current lender.
- Lenders Mortgage Insurance, a one-off premium some lenders require if the new loan pushes your loan-to-value ratio above the lender’s threshold, commonly around 80%. Thresholds vary and can change. It protects the lender, not you, if the loan defaults.
- The chance of re-accumulating debt. Consolidating doesn’t address the spending habits that created the debt in the first place, and some borrowers find themselves in a similar position again within a few years.
When It Tends to Make Sense
Whether this makes sense largely comes down to your equity position, and that’s changed for a lot of Perth homeowners in recent years. Recent REIWA market data has pointed to a strong Perth Metro market, but exact median figures move as new sales settle. If you bought several years ago, property value growth across Perth and the wider Western Australia market may mean you have more usable equity than you’d expect. It’s worth checking with a Perth mortgage broker before ruling consolidation in or out.
A debt consolidation home loan may be worth exploring when:
- You have sufficient equity in your home, typically a reasonable equity buffer remaining after consolidation, often around 20%, though lender requirements vary and can change.
- The debts you’re rolling in carry high interest rates and would otherwise take years to clear.
- You have stable income and can comfortably service the larger mortgage.
- You have a realistic plan to avoid re-accumulating consumer debt afterwards.
- The monthly cash flow saving is meaningful and goes toward strengthening your financial position, not just easier spending elsewhere.
A broker can model the true cost of consolidation in these situations and compare it against other ways of tackling the same debts.
When It’s Worth Avoiding
Refinancing to consolidate debt isn’t right for everyone. It’s worth pausing if:
- You have minimal equity, since consolidating could push you into Lenders Mortgage Insurance territory or leave little buffer.
- The debts are relatively small or short-term, where clearing them directly may cost less overall.
- Your spending habits haven’t changed, since consolidating without addressing the cause can mean new debt building on top of a larger mortgage.
- You’re close to paying off your home, because extending the loan term to clear consumer debt can significantly delay that milestone.
- Your income or employment is unstable, since consolidation increases your secured debt at a time when certainty matters most.
A broker who’s being straight with you will say when consolidation isn’t the right move, even if that means less business for them.
A Worked Example (Illustrative Only)
Say a Perth homeowner has $20,000 in credit card debt at 19% interest, currently being repaid at $500 a month. At that rate, it would take just over five years to clear, and cost roughly $12,000 in interest.
If that $20,000 is rolled into a home loan at 6% over the remaining 25 years of the mortgage, the monthly repayment might increase by only around $129. Over the full 25 years, that same $20,000 could accumulate approximately $18,600 in interest, around 56% more than tackling the credit card debt directly in its original timeframe.
The monthly cash flow benefit may be real. So can the longer-term cost. Weighing both is what leads to a properly informed decision. The right answer depends on your equity position, your current interest rates, your loan term, and what you’d do with the freed-up cash each month.
This example is illustrative only. Actual figures depend on your specific rates, loan terms and financial circumstances, and a broker can model your real numbers rather than a general example.

Frequently Asked Questions
What is a debt consolidation home loan?
A debt consolidation home loan is when you increase your existing mortgage, or refinance to a new one, to pay out other debts such as credit cards or personal loans. It replaces multiple repayments with a single one, often at a lower interest rate, but spreads the debt over your home loan’s longer term.
Is a debt consolidation home loan the same as a personal loan for debt consolidation?
No. A personal loan for debt consolidation is a separate, unsecured loan. A debt consolidation home loan uses the equity in your property and increases your existing mortgage, which means the consolidated debt becomes secured against your home.
Will consolidating debt into my home loan save me money?
It may lower your monthly repayments, but spreading debt over a longer loan term can increase the total interest paid over time. Whether it saves you money overall depends on your interest rates, your remaining loan term and how much equity you have. We recommend having a broker model your specific numbers.
How much equity do I need to consolidate debt into my mortgage?
This varies by lender, but you will usually need a reasonable equity buffer remaining in your home after the consolidation to avoid Lenders Mortgage Insurance and keep a margin of safety. Requirements commonly sit around 20%, but they vary and can change. This is closely related to how much you could borrow with a home equity loan more broadly, and a broker can assess your specific equity position. If your goal is buying before selling rather than paying out debts, our bridging loan guide covers that scenario separately.
Can I consolidate any type of debt into my home loan?
Most lenders will consider credit cards, personal loans and car loans. Some debts or circumstances may not be suitable for consolidation, and a broker can talk through which of your debts make sense to roll in and which don’t.
