Consolidating debt into your home loan through refinancing can reduce your monthly repayments significantly, but only if the numbers work and you change the behaviour that created the debt.
Many McKinnon residents carry a mix of personal loans, car finance, and credit card debt alongside their mortgage. When these debts carry interest rates between 8% and 22%, rolling them into a home loan at a lower interest rate can free up hundreds of dollars each month. The question is whether extending short-term debt over 25 or 30 years makes sense for your situation, and whether you'll end up paying more interest overall.
What Debt Consolidation Through Refinancing Actually Means
You're replacing your existing home loan with a new one that has a higher loan amount, using the additional funds to pay out other debts. The lender assesses whether you can service the new loan amount and whether your property has sufficient equity to support the increase. Most lenders require you to retain at least 20% equity after consolidation to avoid lenders mortgage insurance, though some will lend up to 90% of your property's value depending on your income and credit profile.
Consider a McKinnon homeowner with a $450,000 mortgage, a $25,000 car loan at 9%, and $15,000 in credit card debt at 18%. They're paying roughly $2,800 per month on the mortgage, $650 on the car, and $400 minimum on the cards. By refinancing to a single $490,000 home loan, their monthly commitment drops to around $3,100. That's $750 per month back in their cashflow, which can be redirected toward an offset account or other financial goals.
How Equity Requirements Affect Your Consolidation Options
Your available equity determines how much debt you can consolidate. Lenders calculate usable equity as 80% of your property's current value, minus your existing mortgage. If your McKinnon home is valued at $1.1 million and you owe $450,000, your usable equity sits at $430,000. That's more than enough to absorb $40,000 in consumer debt and cover refinancing costs.
If your equity is tighter, you may need to accept a higher interest rate or pay lenders mortgage insurance to proceed. Some lenders will go to 90% or even 95% loan-to-value ratio for debt consolidation, but the cost of insurance often erodes the benefit of consolidating in the first place. Running a detailed loan health check before applying helps you understand whether your equity position supports consolidation without adding unnecessary costs.

The Real Cost of Extending Debt Over Your Loan Term
Consolidating short-term debt into a 30-year mortgage reduces your monthly repayments, but it also means you're paying interest on that debt for decades unless you make extra repayments. A $15,000 credit card paid off over three years at 18% costs roughly $6,500 in interest. Roll that same $15,000 into a 30-year mortgage at 6%, and you'll pay over $17,000 in interest if you only make minimum repayments.
This doesn't mean consolidation is a poor choice. It means you need a plan to pay down the consolidated amount faster than the loan term. Setting up an offset account and depositing your freed-up cashflow into it reduces the interest charged on your loan without locking those funds away. Alternatively, increasing your repayment amount by even $200 per month can shave years off your loan and thousands in interest.
When Consolidation Makes Sense and When It Doesn't
Consolidation works when your primary issue is cashflow, not spending. If you've accumulated debt due to a one-off expense like medical bills, a vehicle purchase, or covering costs during parental leave, and you're now in a stable income position, consolidating into your mortgage gives you breathing room while you rebuild savings.
It doesn't work if the debt stems from ongoing overspending. Rolling $20,000 of credit card debt into your mortgage only to run up another $20,000 over the next two years leaves you worse off than when you started. Lenders will assess your credit history and spending patterns during the refinance application, and multiple instances of consolidation followed by re-accumulation can make approval difficult.
How Lenders Assess Your Debt Consolidation Application
Lenders calculate serviceability by comparing your income to your total monthly commitments, including the new loan amount. They'll also review your credit file for missed payments, defaults, or patterns that suggest financial stress. If you've been making only minimum payments on multiple debts for an extended period, some lenders may decline the application or offer a higher rate.
McKinnon's proximity to Southland Shopping Centre and the retail precincts along North Road means many residents work in professional or healthcare roles with stable income, which lenders view favourably. If you're self-employed or have a variable income, expect to provide additional documentation such as tax returns and business financials. Some lenders are more flexible with debt consolidation for self-employed borrowers, while others apply stricter criteria.
Fixed or Variable Rate After Consolidation
Once you've consolidated, you'll need to choose between a fixed rate, variable rate, or split. A variable rate gives you flexibility to make extra repayments without penalty and access features like offset and redraw. A fixed rate locks in certainty but typically restricts additional repayments to $10,000 or $20,000 per year.
If your priority is paying down the consolidated debt quickly, a variable rate with offset makes sense. If you need predictable repayments and aren't planning to make extra payments in the short term, a fixed rate or split structure might suit. Many McKinnon borrowers coming off a fixed rate period use the opportunity to consolidate debt and reassess their rate structure at the same time.
Refinancing Costs and How They Affect the Outcome
Refinancing to consolidate debt typically costs between $1,500 and $3,000, covering discharge fees from your current lender, application fees, valuation, and legal costs. Some lenders will capitalise these costs into the new loan, but that increases your loan amount further. If your monthly saving from consolidation is $750 and your costs are $2,500, you break even in under four months. Beyond that, the benefit is tangible.
If you're already planning to refinance for another reason, such as accessing a lower interest rate or switching lenders, consolidating debt at the same time adds minimal extra cost. The property valuation and application process are the same whether you're refinancing your existing balance or increasing the loan amount.

Frequently Asked Questions
How much equity do I need to consolidate debt into my home loan?
Most lenders require you to retain at least 20% equity after consolidation to avoid lenders mortgage insurance. If your property is valued at $1 million and you owe $400,000, you could consolidate up to $400,000 in debt while staying within this threshold.
Will consolidating debt into my mortgage save me money?
It depends on how quickly you repay the consolidated amount. Consolidation reduces your monthly repayments by replacing high-interest debt with a lower home loan rate, but extending that debt over 30 years can cost more in total interest unless you make extra repayments or use an offset account.
What costs are involved in refinancing to consolidate debt?
Refinancing typically costs between $1,500 and $3,000, including discharge fees, application fees, valuation, and legal costs. Some lenders allow you to add these costs to your new loan amount, though this increases the total amount you'll repay.
Can I refinance to consolidate debt if I'm self-employed?
Yes, though you'll need to provide additional documentation such as tax returns and business financials. Some lenders are more flexible with self-employed borrowers for debt consolidation, while others apply stricter serviceability criteria.
Should I choose a fixed or variable rate after consolidating debt?
A variable rate offers flexibility for extra repayments and access to offset, which helps you reduce interest faster. A fixed rate provides repayment certainty but typically limits additional repayments to a set amount per year.
