Can I Consolidate Credit Cards, Car Loans or Personal Debt Into My Mortgage?
If you've got a mortgage, car loan, credit card and maybe a personal loan, it can start to feel like money is disappearing in every direction.
Different repayments. Different interest rates. Different due dates.
And sometimes the problem isn't that you've been irresponsible with money. Life just gets expensive. The car needed replacing. School costs increased. A credit card helped get you through a tighter period. Income temporarily dropped. One expense became another and suddenly you're managing several debts every month.
For homeowners with enough equity and borrowing capacity, one option may be to consolidate some of those debts into your home loan. Done properly, this can simplify your finances and potentially reduce the amount you need to find each month. But timing and structure matter.
What does debt consolidation through your home loan actually mean?
Debt consolidation means replacing several existing debts with a new lending structure.
Rather than continuing to make separate repayments on your mortgage, car loan, credit card and personal loan, you may be able to refinance or restructure your home lending and use available equity in your property to pay out some of those debts.
Because home-loan rates are generally lower than rates on unsecured debts such as credit cards and some personal loans, this can potentially reduce interest costs and improve monthly cash flow.
But a lower repayment doesn't automatically mean cheaper debt. The way the new lending is structured matters enormously.
Why timing matters: speak to your broker before you start missing repayments
This is probably the most important thing I want homeowners to understand.
If you can already see that your finances are getting difficult to manage, don't wait until repayments start being missed before asking for help.
When repayments are up to date and your credit conduct remains strong, your broker will generally have a broader range of lenders and options to compare. That gives us a better chance of finding a competitive interest rate and lending structure.
Once repayments have started falling behind, there can still be refinance options available - but it gets harder. Fewer lenders may accept recent adverse credit history or missed repayments, and those options can come with higher interest rates, fees or other costs than standard lending.
So if you're thinking, "I don't know how we're going to keep doing this," that is the time to talk to your broker.
The earlier we understand what's happening, the more options we usually have.
Do I have to roll all of the debt into a 30-year mortgage?
No - and this is something a lot of our clients are surprised to learn.
One of the biggest risks with debt consolidation is taking a debt that may originally have been repaid over three, five or seven years and spreading it across a 25- or 30-year home loan.
The required repayment might look much lower, but if you then spend 30 years paying that debt back, you could pay much more interest overall.
That's why the consolidated debt can often be kept in a separate loan split.
A simple way to picture it
Home loan split 1: your existing mortgage, continuing over its appropriate remaining term.
Home loan split 2: the consolidated debt, set up over a shorter period such as five, seven or ten years.
That second split is still lending secured against your home and may be with the same bank as your main mortgage, but keeping it separate makes it easier to see exactly what that debt is doing and create a clear plan to pay it off.
The goal isn't simply, "How low can we make the repayment?" It should be, "How can we create breathing room now while still having a sensible plan to get this debt gone?"
Your broker should look at more than just the interest rate…
Some car loans, personal loans and other finance products may have payout fees, early repayment fees, discharge fees or other costs for closing the loan early. There may also be costs involved in setting up the new lending.
This is why looking at the interest rate alone can be misleading.
You could find a much lower rate elsewhere, but if an existing loan has a large payout fee, some or all of that benefit may disappear.
Your broker can help collect the payout figures, compare the cost of changing and work through whether the proposed refinance actually leaves you better off overall.
At Rockett Finance, we look at the whole outcome: rates, repayments, loan terms, costs of changing, cash flow, equity and your longer-term plan for getting the debt paid down.
When can debt consolidation genuinely help?
It may be worth exploring when several debts are creating high combined monthly repayments, you're paying higher interest on consumer debts, you want fewer repayments to manage, or the debt accumulated during a temporary period such as parental leave, reduced hours or unusually high expenses.
There can be real value in being able to see: this is the home loan, this is the debt we're clearing, and this is when we expect it to be gone.
When might debt consolidation not solve the problem?
Debt consolidation can tidy up an existing problem. It doesn't necessarily fix the reason the debt accumulated.
If a household is consistently spending more than it earns, consolidating everything and then starting to use the credit cards again can leave someone in a worse position.
That's why part of the conversation should be: what created the debt in the first place? Was it temporary, a one-off expense, higher rates, reduced income - or an ongoing monthly shortfall?
If credit cards are paid out as part of the refinance, it may also be appropriate to reduce or close those limits so the same debt doesn't slowly build back up again.
Do a 10-minute debt snapshot before speaking to your broker
You don't need a perfect spreadsheet. Write down each debt's balance, interest rate and monthly repayment. Then total your debt outside the mortgage and your monthly repayments outside the mortgage.
That alone can be eye-opening. Send the information to your broker and let them help work through the options. You don't need to know whether debt consolidation is the answer before you ask. That's what the review is for.
Ready to see what your debts could be doing better?
If your debts are starting to feel like they're pulling money in every direction, you don't need to solve it all yourself.
If you can see repayments getting harder to manage, talk to us before you fall behind if you can.
At Rockett Finance, we can look at your current home loan, other debts and repayments, available equity, repayment history, payout costs, lender options and what you want your finances to look like next.
We can then help work through whether refinancing or restructuring could simplify things, reduce the pressure on monthly cash flow and create a clearer plan for getting the debt paid off.
Most importantly, the aim isn't just to move debt from one place to another. It's to help you tidy things up, create breathing room and build a better path toward becoming debt free.

Frequently Asked Questions (FAQs)
-
Potentially. Some lenders may consider applications with recent adverse credit history or missed repayments, but the lender pool may be smaller and rates or fees may be higher. It is worth speaking to your broker as early as possible.
-
Potentially, yes. Available equity, borrowing capacity, credit history, the existing debts and lender policy will all matter. Your broker should also check any payout costs before recommending a refinance.
