For many Australian homeowners, high-interest credit cards, personal loans and buy-now-pay-later balances can quietly become a heavy monthly burden. One option often raised is using the equity built up in a home to consolidate that debt into a single, lower-rate facility. It can be a genuinely useful strategy in the right circumstances, but it changes the nature of the debt in an important way, so it deserves a clear-eyed explanation before anyone acts on it.
What “using equity to consolidate debt” actually means
Home equity is the difference between your property’s current market value and what you still owe on your mortgage. If your home is worth $700,000 and you owe $400,000, you have roughly $300,000 in equity, though lenders will only let you access a portion of that (commonly up to 80% of the property’s value minus what you owe, before lender’s mortgage insurance considerations apply).
Debt consolidation using that equity generally happens one of two ways:
- Refinancing your home loan for a larger amount (a “cash-out” refinance) and using the extra funds to pay off credit cards, personal loans or other unsecured debts.
- Establishing a line of credit or home equity loan secured against the property, then drawing on it to clear existing debts.
In both cases, debts that were previously unsecured — meaning a lender had no direct claim over an asset if you defaulted — become secured against your home. According to ASIC’s MoneySmart guidance on debt consolidation and refinancing, this is the central trade-off: you may get a lower interest rate, but if you cannot meet repayments, the home used as security can be sold by the lender to recover the money owed.
Why the interest rate isn’t the whole story
Credit card rates in Australia often sit well above home loan rates, so folding that debt into a mortgage can look like an immediate win. However, mortgages are typically repaid over much longer terms, often 25 to 30 years, than the original personal loan or credit card would have taken to clear. MoneySmart’s guidance is explicit that consolidation only tends to work when the new loan term isn’t longer than the terms of the debts being replaced, and when the borrower actually pays less overall once fees and interest are accounted for.
As a simple illustration: paying off a $20,000 credit card balance at a high interest rate over three years may cost less in total interest than spreading that same $20,000 across the remaining 25 years of a home loan, even at a much lower rate, because interest compounds over a longer period. This is arithmetic, not a guarantee that the actual outcome depends on your specific rate, term and repayment behaviour, and you should ask your broker or lender to model it against your numbers.
What ASIC’s review found
In its review of the debt consolidation sector, ASIC found inconsistent practices among some providers, including insufficient documentation of a consumer’s existing debts, inadequate discussion of the risks and costs involved, and cases where old credit facilities were left open — allowing consumers to redraw on them and accumulate new debt on top of the consolidated amount. ASIC’s Deputy Chairman at the time noted that while consolidation can be beneficial, it is not appropriate for every borrower, and any provider recommending it should be satisfied the strategy suits the consumer’s actual circumstances and is affordable long term.
The practical takeaway is that consolidation is a tool, not a fix. If underlying spending habits or income pressures aren’t addressed, moving debt onto the home can leave a person more exposed, not less, because more of their overall wealth is now tied to a single secured facility.
Questions worth asking before you proceed
- How much usable equity do you actually have once the lender’s maximum loan-to-value ratio is applied?
- What is the full new loan term, and how does the total interest compare with paying out your current debts on their existing terms?
- Will old credit cards or personal loan facilities be closed once consolidated, to avoid re-accumulating debt?
- What fees apply to refinancing or establishing a line of credit, and are they factored into the comparison?
- Can your income comfortably support the new repayments if interest rates rise?
Where a broker fits in
A finance broker can model these scenarios against your real numbers, compare lenders, and help identify whether refinancing, a line of credit, or another approach, such as negotiating directly with existing creditors or a structured repayment plan, better suits your situation. Because every household’s income, debts and goals differ, this article is general in nature and doesn’t replace tailored advice.

TL;DR
- Consolidating debt into your home loan can lower your interest rate, but it turns unsecured debts into debt secured against your home.
- A longer loan term can mean paying more total interest even if your monthly repayment feels smaller, so compare total cost, not just the rate.
- ASIC’s review found consolidation isn’t right for everyone; it works best when you close old accounts and stop taking on new unsecured debt.
- Accessing equity usually means refinancing or a line of credit, both of which require enough equity, serviceability and lender approval.
- Speak with a qualified broker or financial adviser about your specific numbers before using your home as security for other debts.
Frequently Asked Questions
It means borrowing against the value built up in your home, usually through refinancing or a line of, credit to pay off other debts like credit cards or personal loans, replacing several repayments with one loan secured against your property.
Yes, in an important way: credit card debt is usually unsecured, but once it’s rolled into a home loan or equity line, it becomes secured against your house. If you can’t keep up repayments, the lender may be able to sell your home to recover what’s owed.
It can, but not always. A lower interest rate can be offset by a much longer repayment term, so it’s important to compare total interest and fees over the full loan term, not just the monthly repayment or the headline rate.
Lenders typically cap borrowing at a percentage of your property’s value (commonly up to around 80%) minus what you still owe, and the exact amount depends on your income, existing debts and the lender’s serviceability assessment.
Generally yes. ASIC’s review of the sector found that leaving old credit cards or loan facilities open after consolidation lets some people redraw on them, accumulating new debt on top of the consolidated amount.
