You've been managing your car loan, a couple of credit cards, and maybe an old personal loan for years.
Now that you're thinking about buying your first home together, those repayments feel like they're standing in the way. They eat into your savings capacity, reduce how much lenders think you can borrow, and make it harder to demonstrate the clean financial position that mortgage applications demand.
Debt consolidation refinancing can change that picture. It involves replacing your current home loan with a new one that includes enough to pay out those other debts, leaving you with a single repayment at a lower overall interest rate. For couples trying to position themselves as first home buyers, this can unlock borrowing capacity and monthly cashflow that otherwise wouldn't exist.
What debt consolidation refinancing actually does
It replaces multiple high-interest debts with a single home loan.
Consider a couple who own a small unit in Oakleigh, purchased four years ago. They have $320,000 remaining on their mortgage, a car loan with $18,000 outstanding at 9.5%, and a personal loan sitting at $12,000 with an interest rate around 13%. Between those three commitments, they're paying just over $3,400 per month. When they apply to borrow more to upgrade to a house, the lender assesses their ability to service another loan while those commitments are still active. Their borrowing capacity is capped before they even get close to what they need.
By refinancing their home loan to $350,000, they clear both the car and personal loan entirely. Their new mortgage repayment sits around $2,300 per month depending on the rate they secure. That's over $1,100 back in their budget every month, and it also removes two ongoing commitments from their credit file, which changes how much a lender will let them borrow for the next property.
How lenders assess your application differently after consolidation
Lenders calculate serviceability based on all your current commitments, not just your mortgage.
When you carry a personal loan or credit card with a $10,000 limit, the lender doesn't just look at your current balance. They assume you could max it out tomorrow and assess whether you'd still be able to afford the mortgage repayments. A $10,000 credit card limit can reduce your borrowing capacity by $50,000 or more, even if you never use it.
Once those debts are consolidated into your mortgage and the accounts are closed, your financial position looks completely different on paper. The lender sees one loan secured against property at a much lower rate than unsecured lending. Your monthly commitments drop, your disposable income increases, and suddenly the amount you can borrow for your first home moves up significantly.

When refinancing to consolidate makes sense and when it doesn't
This approach works when the interest you save outweighs the cost of refinancing and the extended repayment term.
If you're paying 12% on a personal loan and 20% on a credit card, moving that debt to a mortgage at 6% will save you money in interest every month. But because home loans run over 25 or 30 years, you'll be paying off that $12,000 personal loan for much longer unless you make extra repayments. The total interest paid can end up higher, even at a lower rate, purely because of the extended timeframe.
It makes sense if you're planning to use the improved cashflow to save a deposit, pay down the consolidated loan faster, or increase your borrowing capacity for a property purchase in the near term. It doesn't make sense if you're just trying to reduce monthly pressure without a clear plan, because you'll likely pay more over the life of the loan and you'll be using your home as security for what was previously unsecured debt.
Most lenders will also charge a discharge fee on your current loan, and there may be application or valuation fees on the new one. If your current loan has a fixed rate that hasn't expired yet, break costs can add thousands to the exercise. You need to weigh those upfront costs against the monthly savings and the benefit to your borrowing position.
The application process and what lenders want to see
You'll need to demonstrate that consolidating the debt improves your financial position, not just your comfort.
Lenders will ask for statements showing your current debts, and they'll want to see that you've been meeting your repayments consistently. If your credit file shows missed payments or defaults, consolidation becomes harder to justify because the lender sees you as higher risk. They'll also want evidence that you're not going to rack up those credit cards again once they're cleared. In our experience, lenders often ask for a letter confirming that cards and personal loan accounts will be closed once the refinance settles.
You'll also need a property valuation. If your home's value has increased since you bought it, you'll have more equity available to borrow against. If it's stayed flat or dropped, you may not be able to access enough to clear all your debts without paying lenders mortgage insurance again.
The refinance application itself takes a similar shape to your original mortgage. Income verification, living expenses, credit checks, and a full assessment of your financial position. The difference is that this time, the outcome should leave you in a stronger position to move forward with your first home purchase as a couple.
How this positions you for a first home purchase
Clearing your debts and improving your cashflow can bring forward your timeline by months or even years.
If you're currently saving $800 per month toward a deposit and you free up another $1,100 through consolidation, you're now putting away $1,900. That shortens the time it takes to reach your target. It also means that when you do apply for a home loan, your serviceability is calculated on a much cleaner base. The borrowing capacity you gain from removing those other commitments can be the difference between being able to afford a two-bedroom unit or a three-bedroom house in the same area.
For first home buyers using schemes like the First Home Guarantee, where a 5% deposit is acceptable, every month of improved savings velocity matters. The sooner you hit that deposit threshold, the sooner you can buy. And because those schemes have annual caps on how many applicants they accept, timing can determine whether you're in or waiting another year.
What happens to your offset and redraw after refinancing
You may lose access to any funds sitting in offset or redraw on your current loan when you refinance.
If you've been building up a buffer in an offset account or making extra repayments into a loan with redraw, moving to a new lender usually means starting fresh. Some lenders will let you transfer that balance across if your new loan includes an offset account, but it's not automatic. You need to structure the new loan with those features from the start, and not every loan product that suits debt consolidation will include them.
If maintaining access to those funds is important for your deposit or for upcoming costs, make sure the loan you refinance to has an offset account or redraw facility that works the way you need it to. Otherwise, that money gets absorbed into your loan balance and you'll need to re-borrow or withdraw it, which can trigger additional assessments or fees.

Frequently Asked Questions
Does refinancing to consolidate debt improve my borrowing capacity?
Yes, consolidating high-interest debts into your mortgage removes those commitments from your serviceability assessment. Lenders will see one loan at a lower rate instead of multiple debts, which can increase how much they're willing to lend you for a property purchase.
Will I pay more interest overall if I consolidate debt into my mortgage?
You'll pay a lower interest rate, but because home loans run for 25 or 30 years, you may pay more total interest unless you make extra repayments. The benefit comes from improved monthly cashflow and borrowing capacity, not necessarily from paying less interest over the life of the loan.
What happens to my credit cards after I refinance to consolidate them?
Lenders will typically ask you to close the accounts once the refinance settles. Keeping them open can reduce your borrowing capacity for future purchases because lenders assume you could max them out again, even if the balance is zero.
Can I still refinance if my property value hasn't increased?
You can, but you may not have enough equity to consolidate all your debts without paying lenders mortgage insurance again. A property valuation will determine how much you can borrow, and if your equity hasn't grown, your options may be limited.
How long does the refinance process take when consolidating debt?
The process usually takes three to six weeks depending on the lender and how quickly you can provide documentation. You'll need to supply statements for all debts being consolidated, proof of income, and go through a full credit assessment before the new loan settles.
