Debt consolidation into your home loan
A credit card, a car loan, an afterthought personal loan, each with its own rate, its own due date, each priced higher than your mortgage. Rolling them into the home loan can genuinely simplify your month and cut what you pay. It can also quietly convert five years of car debt into thirty years of interest. Both outcomes come from the same product; the difference is entirely in how it's structured.
How consolidating debt into your home loan works
Consolidation is a refinance with a purpose: your home loan is increased (or moved to a new lender at a higher amount), and the released funds pay out the other debts at settlement. You emerge with one repayment at home-loan pricing instead of several at card and personal-loan pricing. The lender assesses the enlarged loan against your income and your property's value, so equity and serviceability both need to support it, the equity calculator shows the first half of that equation.
The honest arithmetic
Here is the part the glossy versions of this page omit: a mortgage rate is lower per year, but a mortgage runs for decades. Debt that would have been extinguished in four years, spread across a thirty-year term, can accrue more total interest than it ever would have at the higher rate, while feeling cheaper every single month. The monthly relief is real; so is the long-term cost. Any consolidation we arrange comes with both numbers in front of you.
The structure that keeps it honest
The fix is simple and almost never advertised: keep paying the consolidated portion at the old pace. Direct the repayments you were already making, the card payment, the car payment, into the mortgage as extra repayments, or structure the consolidated slice as a separate split with its own shorter term. The debts die on something like their original schedule, at the lower rate, and the mortgage doesn't absorb them into its decades.
When it genuinely helps
When high-rate debts are straining an otherwise sound budget. When repayment clutter is causing missed payments that damage your credit file. When a single lender assessment beats juggling five. When it's paired with a refinance that was worth doing anyway, one application, one settlement, a cleaner position and often a sharper rate at the same time.
Same product. Two outcomes.
Everything on this page comes down to which of these columns you end up in, and that's decided by structure and habit, not by the loan.

When it hurts, said plainly
Consolidation clears the cards; it doesn't change what filled them. If spending continues at the old pattern, the cards refill on top of the enlarged mortgage, and the position eighteen months later is worse than the starting one, now with the debt secured against your home. That last clause deserves weight: unsecured debt becomes secured debt. A card company can chase you; a mortgagee can sell the house. Consolidation converts nuisance into stakes.
It also isn't a tool for a budget that's already failing. If repayments are being missed and the direction is downward, adding debt to the home is the wrong instrument, a financial counsellor is the right first call, and the National Debt Helpline (1800 007 007) is free. We say this on the record because a broker who'd rather write a loan than say it is one of the red flags on our choosing a broker page.

OpenConsolidation questions
What debts can be consolidated into a home loan?
Commonly credit cards, personal loans and car loans; some lenders will include tax debt or buy-now-pay-later balances, with policies varying widely. Each debt appears on the application with a payout figure, and the lender confirms the debts are actually closed at settlement, not just paid down and left open.
Will consolidating hurt my credit score?
The application itself adds an enquiry, as any application does. Beyond that, consolidation often helps the file over time: fewer accounts, no juggled due dates, cleaner repayment history. Closing the paid-out cards matters, open cards with zero balances still count their limits against your future borrowing power.
How much equity do I need?
The enlarged loan generally needs to stay within 80% of your property's lender-assessed value to avoid lenders mortgage insurance, so the room available is 80% of value, minus your current balance. Serviceability is assessed alongside: the lender must be satisfied your income carries the new total at a buffered rate.
Can I consolidate if my repayments are already behind?
Arrears narrow the field but don't always close it, some lenders will consider a consolidation that demonstrably improves your position, and specialist lenders exist for harder files. Be honest with yourself about direction first: if the budget doesn't work even after consolidation, a financial counsellor is the right call before any application, and we'll say so if that's what your numbers show.
Is it better to consolidate or just refinance?
They're the same transaction at different sizes, consolidation is a refinance that also clears other debts. If your other debts are small and well-managed, a straight refinance for a sharper rate may be all you need. If they're expensive and cluttering the budget, folding them in while you're refinancing anyway costs one application instead of two. We price both versions side by side.
