Company directors in Sydney often accumulate debt across multiple facilities: business overdrafts, equipment finance, corporate credit cards, and personal loans.
The interest rate spread between these debts and a secured mortgage can be significant. Where your home loan might sit at a variable interest rate around 6-7%, business overdrafts and credit cards frequently charge 12-20%. Consolidating these debts into your mortgage through refinancing reduces the weighted average interest rate across all your borrowing, which directly improves monthly cashflow. For directors drawing income from their company, this can mean the difference between maintaining reserves and operating under constant pressure.
How Debt Consolidation Through Refinancing Works
Refinancing to consolidate debt involves replacing your current mortgage with a new loan that includes both your existing home loan amount and the debts you want to pay out. You access equity in your property to clear higher-interest obligations, then repay everything through a single monthly mortgage payment at a lower interest rate.
Consider a director who owns a property in Mosman valued at $2.1 million with a mortgage of $900,000. They also carry $150,000 in business debt: $80,000 on a commercial overdraft at 14%, $50,000 in equipment finance at 9%, and $20,000 on corporate cards at 18%. Their monthly repayments across these debts total around $8,200. By refinancing to a $1,050,000 mortgage and consolidating all debts, their single monthly payment drops to approximately $6,800. The monthly saving of $1,400 goes directly back into the business or personal reserves.
The equity required for this consolidation is the difference between the property value and the new loan amount. At $1,050,000 borrowed against $2.1 million, the loan-to-value ratio sits at 50%, well within most lender comfort zones for self-employed borrowers.
When Consolidation Makes Financial Sense
Consolidation through refinancing works when the cashflow improvement justifies the shift from unsecured to secured debt. The calculation comes down to monthly payment reduction versus the extended repayment period.
Unsecured business debt typically requires repayment within 1-5 years. A mortgage extends that to 25-30 years. While you reduce monthly pressure, you increase the total interest paid over time unless you maintain higher repayments once cashflow improves. Directors who consolidate should treat the mortgage payment as a floor, not a ceiling, and direct surplus cashflow toward paying down the principal faster.
Consolidation makes particular sense when business debt is constraining growth. If high monthly debt repayments prevent you from taking on new contracts, hiring staff, or holding adequate inventory, the immediate cashflow relief from consolidation can unlock revenue opportunities that outweigh the longer-term interest cost.
The Serviceability Challenge for Company Directors
Lenders assess self-employed borrowers differently to wage earners. Where an employee presents payslips, company directors must demonstrate income through tax returns, company financials, and accountant declarations. This becomes more complex when refinancing to increase your loan amount for debt consolidation.
Most lenders will add back the monthly payments you're consolidating when calculating your borrowing capacity. If you're currently paying $3,000 per month across business debts, and those debts will be cleared through the refinance, lenders typically allow that $3,000 to support the increased mortgage payment. However, they still require your current income to service the new loan amount at their assessment rates, which sit 2-3% above actual rates.
For directors in areas like the Lower North Shore or Eastern Suburbs, where property values support substantial equity release, the borrowing capacity calculation becomes the binding constraint more often than available equity. A director with $400,000 in accessible equity might only qualify to borrow an additional $200,000 based on their declared income, particularly if they've structured their affairs to minimise personal tax.
Structuring the Refinance Application
The refinance application for debt consolidation requires documentation that satisfies both the income assessment and the purpose of funds. Lenders want to see exactly which debts you're clearing and confirmation that those funds will be applied directly to those obligations.
You'll need statements for each debt showing current balances, the account details for payout, and an explanation of how the debts were used. Business debts incurred for equipment, stock, or operational expenses are viewed more favourably than personal spending. Lenders may question consolidating debts that appear to fund lifestyle rather than income-generating activity, particularly for self-employed borrowers whose income fluctuates.
Working with a mortgage broker who regularly structures applications for company directors helps here. The presentation of your income through the lens lenders prefer - whether that's individual tax returns, company distributions, or a combination - determines whether the application succeeds. Small changes in how income is documented can shift a declined application to approval.
Fixed Versus Variable After Consolidation
After consolidating debt into your mortgage, you'll need to choose between fixed and variable interest rates or a split between both. This decision affects your ability to make additional repayments and your exposure to rate movements.
Variable rates allow unlimited extra repayments and access to offset accounts. If your income as a company director varies seasonally or project-by-project, parking surplus funds in an offset account against a variable loan reduces interest daily without locking the funds away. You maintain liquidity while reducing interest costs. Fixed rates provide payment certainty but typically restrict additional repayments to $10,000-$30,000 per year. For directors expecting to generate surplus cashflow after consolidation, this can become restrictive.
Some directors coming off a fixed rate period use that refinance trigger to simultaneously consolidate debt. If your fixed term is ending and you're already engaging with the refinance process, incorporating debt consolidation adds minimal additional complexity while maximising the value of that single transaction.
Tax Implications of Consolidating Business Debt
Consolidating business debt into a mortgage secured by your personal residence changes the tax treatment of interest payments. Interest on debt used for business purposes is typically tax-deductible. When that debt moves into a home loan, you need to maintain clear separation between the portion used for investment or business purposes and the portion secured against your home.
Most lenders and accountants recommend splitting the loan into separate accounts: one for the original home loan, one for the consolidated business debt. This preserves the deductibility of interest on the business portion. Without this split, the entire loan becomes mixed-purpose, and untangling the deductible portion each financial year becomes complicated.
Your accountant should review the consolidation structure before you proceed. The cashflow improvement needs to exceed any additional tax payable from reduced deductions. In some cases, the monthly saving from lower rates outweighs the tax impact. In others, particularly where the director's marginal tax rate is high, maintaining separate business facilities may prove more cost-effective despite higher interest rates.
Property Valuation and Usable Equity
The amount you can consolidate depends on the lender's assessment of your property value and their maximum loan-to-value ratio. Most lenders cap refinances at 80% of property value without requiring mortgage insurance, though some will extend to 90% for well-qualified borrowers.
Sydney's property market creates substantial equity for long-term owners, particularly in established suburbs like Manly, Paddington, or Hunters Hill. A property purchased a decade ago for $1.2 million might now be valued at $2 million or more, creating accessible equity even with modest mortgage reduction over that period. However, lenders will commission their own valuation as part of the refinance application. That valuation may come in below recent sales or your expectation, particularly if comparable sales are limited or market conditions have softened.
If the valuation restricts how much you can borrow, you may need to prioritise which debts to consolidate. Clearing the highest-interest obligations first - typically credit cards and overdrafts - delivers the greatest monthly saving per dollar of equity used. Lower-rate debts like equipment finance might remain separate if equity is insufficient to consolidate everything.

Frequently Asked Questions
Can I consolidate business debts into my home loan as a company director?
You can consolidate business debts into your home loan by refinancing and accessing equity in your property. Lenders will assess your income as a company director through tax returns and company financials, and they typically add back the monthly payments you're consolidating when calculating your borrowing capacity.
Does consolidating business debt into a mortgage affect tax deductions?
Consolidating business debt into a home loan can affect the tax deductibility of interest payments. Most accountants recommend splitting the loan into separate accounts - one for the original home loan and one for consolidated business debt - to preserve the deductibility of interest on the business portion.
How much equity do I need to consolidate debt through refinancing?
The equity required depends on the total debts you want to consolidate and your property value. Most lenders cap refinances at 80% loan-to-value ratio without mortgage insurance, meaning you need at least 20% equity remaining after consolidation. The lender will commission a valuation to determine your available equity.
Should I choose fixed or variable rates after consolidating debt into my mortgage?
Variable rates suit company directors whose income fluctuates because they allow unlimited extra repayments and offset account access for parking surplus funds. Fixed rates provide payment certainty but restrict additional repayments to around $10,000-$30,000 annually, which can become limiting if you expect to generate surplus cashflow.
Will lenders approve a refinance to consolidate debt if I'm self-employed?
Lenders assess self-employed borrowers through tax returns, company financials, and accountant declarations rather than payslips. They typically add back the monthly payments you're consolidating when calculating serviceability, but your current income must still service the new loan amount at their assessment rates, which sit 2-3% above actual rates.
