Simple hacks to refinance and consolidate debt

Refinancing to consolidate debt can cut your monthly repayments in half

If you're paying 20% interest on a credit card and 12% on a personal loan, rolling those debts into your mortgage at 6% sounds like an obvious win. It usually is, but only if you commit to clearing the debt faster than the mortgage term and avoid racking up new balances once the cards are paid off.

Consider a scenario where someone is carrying $30,000 across two credit cards and a car loan. Monthly repayments total around $1,200. After consolidating into their mortgage, the repayment drops to roughly $400 a month. That frees up $800 in cashflow immediately. The catch is that $30,000 is now secured against the home and stretched over 25 years unless they make extra repayments. Without discipline, they've swapped short-term debt for long-term debt and will end up paying more interest over time, not less.

This is why a loan health check matters before you refinance. It's not just about accessing a lower rate on the mortgage. It's about building a repayment plan that clears the consolidated debt within a set period, usually two to five years, while keeping the mortgage separate.

How refinancing to consolidate debt actually works

You're not just switching lenders. You're borrowing additional funds against your home's equity to pay out unsecured debts in full, then repaying that amount as part of your home loan. The new loan amount becomes your old mortgage balance plus the debts you've cleared.

Lenders assess this differently than a standard refinance. They'll review your credit file, look at what the debts were used for, and calculate your new serviceability based on the higher loan amount. If your borrowing capacity is tight, the consolidation might reduce how much equity you can access later. That's worth knowing upfront, especially if you're planning to buy an investment property or upgrade in the next few years.

Some lenders also prefer that consolidated debt is held in a split or sub-account with a shorter term or higher repayment structure. That keeps it separate from the main mortgage and forces faster repayment. Others allow it to blend into the total loan. The structure you choose changes the outcome.

When the numbers actually stack up on the Gold Coast

Property values across the Gold Coast have held solid, meaning most homeowners who bought more than three years ago are sitting on usable equity. If your home is worth $750,000 and you owe $450,000, you've got around $150,000 in accessible equity at 80% leverage. That's more than enough to clear typical consumer debt and still keep a buffer.

In our experience, clients around Southport and Robina often consolidate debt when refinancing off a fixed rate that's about to expire. They're already reviewing their loan, and it's the right time to restructure everything at once. Rolling a $25,000 personal loan and $15,000 in credit card debt into a refinance while also locking in a lower variable rate can drop total monthly repayments by $900 or more, depending on the rate differential.

That kind of cashflow improvement matters if you're self-employed, commission-based, or managing irregular income. It also matters if you want to redirect funds toward offset accounts or investment contributions instead of servicing high-interest debt.

The offset account strategy that keeps you honest

One of the most underused structures after a debt consolidation refinance is the offset account. Instead of just making minimum repayments on the new loan amount, you park your surplus cash in an offset and let it reduce the interest charged daily. If you've consolidated $40,000 in debt and you're serious about clearing it quickly, you can treat that $40,000 as a mental sub-loan and commit to building your offset balance until it matches that figure.

This gives you the flexibility of access to your cash if something goes wrong, while still cutting interest as if you'd made a lump sum repayment. It's a middle ground between locking funds into the loan via redraw and leaving them in a transaction account earning nothing. The key is discipline. If the offset becomes a spending account, the strategy falls apart.

What lenders actually look at when you apply

Serviceability is the main hurdle. Lenders calculate whether you can afford the new loan amount based on your income, existing commitments, and living expenses. If you're consolidating $50,000 in debt, they won't just add $50,000 to your loan and approve it. They'll assess whether your income can service the higher mortgage repayment and whether you've demonstrated responsible credit behaviour.

If your credit file shows multiple missed payments or defaults, some lenders won't approve a consolidation refinance at all. Others will, but at a higher rate or with a lower loan-to-value ratio. That's where working with a broker makes a difference. We know which lenders are open to consolidation scenarios and which ones will decline based on credit history or debt type.

You'll also need a current valuation. If your property hasn't increased in value or if you've already borrowed heavily against it, you might not have enough equity to consolidate everything. In that case, prioritising which debts to roll in and which to keep separate becomes the conversation.

The risks no one talks about until it's too late

Consolidating debt into your mortgage turns unsecured debt into secured debt. If you default on a credit card, the bank can chase you for the money and damage your credit file. If you default on a mortgage, they can force the sale of your home. That's a significant shift in risk.

It also extends the repayment term unless you actively counteract it. A $20,000 personal loan over five years becomes a $20,000 chunk of a 30-year mortgage unless you structure it differently or make extra repayments. Over the life of the loan, you'll pay far more interest, even at a lower rate, because of the extended term.

Another risk is reloading the debt. We regularly see scenarios where someone refinances to clear $35,000 in credit cards, then 18 months later they've run up another $15,000 in new debt because the cards are still open and the spending habits haven't changed. If you're refinancing to consolidate debt, the first step after settlement is closing those accounts or at least reducing the limits to something manageable.

How much you can actually borrow depends on equity and income

Most lenders will let you borrow up to 80% of your property's value without paying lenders mortgage insurance. If your home is valued at $800,000, that's $640,000. If you currently owe $500,000, you can access up to $140,000 in equity for debt consolidation, renovations, or investment. That's the theory. In practice, your income needs to service the higher loan amount, and the lender will apply a buffer rate when calculating serviceability.

If your income is $120,000 and you're already close to your maximum borrowing capacity, adding another $40,000 in consolidated debt might push you over the limit. That's when the conversation shifts to whether consolidating everything is the right move, or whether paying down some of the debt first and refinancing later makes more sense.

Your borrowing capacity isn't just about equity. It's about income, existing commitments, dependents, and the lender's assessment rate. All of those factors change the amount you can access.

Refinancing while coming off a fixed rate gives you leverage

If your fixed rate period is ending, you're in a strong position to negotiate. Lenders know you're reviewing your loan anyway, and they'll compete for your business. That's the time to consolidate debt, restructure your loan, and lock in a lower rate if one's available. You're already going through the application process, so adding a debt consolidation component doesn't add much friction.

Clients coming off fixed rates around the Gold Coast often find their repayments are about to jump by $400 to $600 a month when they revert to the lender's standard variable rate. Refinancing to a lower rate while also clearing high-interest debt can offset that increase entirely and still improve monthly cashflow.

That's not a small shift. It's the difference between cutting back on discretionary spending and maintaining your current lifestyle while clearing debt faster.
