Consolidating Business and Personal Debts Before Your Next Home Loan

If you’re a small business owner or self‑employed, consolidating business and personal debts before a home loan can help or hurt you. Consolidation usually means refinancing car loans, credit cards, personal loans and sometimes business facilities into your home loan or a new mortgage split. Done well, it can lift borrowing power and tidy your story for lenders. Done badly, it can increase long‑term interest and put your home on the line for business risk.

In plain terms: consolidate debts before a home loan if it 1) clearly improves serviceability, 2) doesn’t starve your business of cash, and 3) doesn’t stretch short‑term debts over decades. Often the best move is to consolidate some personal debts only, and leave core business facilities separate.

Start by mapping every personal and business debt before you decide what to consolidate.

1. What consolidating business and personal debts really means

1.1 The types of debts we’re talking about

For most business owners looking at a home loan, the list of debts usually includes:

• Personal and business credit cards
• Car and equipment finance (sometimes in the business name)
• Personal loans
• Business overdrafts and unsecured business loans
• Tax debts to the ATO (personal or company)
• Trade accounts with suppliers

Consolidation means paying these out with a new or existing home loan, generally secured against your property. This might be:

• A refinance of your current mortgage with a higher limit
• A new loan split dedicated to debt consolidation
• A new home loan if you’re buying, with extra funds to clear old debts

In exchange, you get one larger home loan, usually at a lower rate than most of those smaller debts.

1.2 How lenders really see personal vs business debts

Many business owners assume “that’s a business loan, so lenders won’t count it against me”. In practice, most Australian lenders:

1. Treat any facility with a personal guarantee as a personal commitment, even if the repayments come from the business account. This includes company car loans, overdrafts and some equipment finance.
2. Count vehicle finance as a personal commitment in many cases, even where the loan is in the business name.
3. Look through mixed accounts: if personal and business spending run through the same bank or credit cards, they’ll often take a more conservative view of your income and expenses.

That’s why getting across your full debt picture is so important before you apply. Our broader guide on tidying debts, Tidy Your Debts So Lenders Say Yes To Your Home Loan, walks through that mapping process step by step.

1.3 What consolidation changes (and what it doesn’t)

Consolidating debts into a home loan usually:

• Reduces your minimum monthly repayments (thanks to lower interest rates and a longer term)
• Simplifies your commitments to 1–2 main repayments
• Changes how lenders see your risk, because you’re now putting more on the family home

It does not:

• Make the debt disappear
• Fix overspending habits
• Automatically improve your borrowing power if the new repayments aren’t clearly lower

The question isn’t just “Can I consolidate?” but “Will consolidating leave me safer and closer to my goals in 3–5 years?”

Only some debts should be consolidated into a home loan; others are safer left separate.

2. How consolidation affects home loan approval

2.1 Serviceability: why monthly repayments matter more than balances

Australian lenders don’t just look at how much you owe; they focus on the monthly repayments they must plug into their calculators, plus a buffer.

• Under APRA guidance, banks typically assess your home loan at 3% above the actual interest rate.
• They also use assessed repayments for your other debts, which are often higher than what you pay in practice (especially for credit cards and interest‑only facilities).

Example – before consolidation
You have:

• $15,000 credit card, limit $20,000 (lenders may assume 3% of limit = $600/month)
• $30,000 car loan over 5 years at 9% p.a. (about $622/month)
• $10,000 business overdraft limit – treated as a commitment, say $300/month

Total assessed monthly commitments: $1,522.

If you roll all three into a home loan split at, say, 6.5% over 10 years, the repayment is around $693/month. That’s a reduction of roughly $829/month on paper, which can significantly boost your borrowing capacity.

This is why consolidation can be powerful for self‑employed borrowers: it cuts the assessed monthly load that’s strangling your serviceability.

2.2 Credit score and conduct

Lenders also review how you’ve handled debts over the last 6–12 months:

• Are repayments on time?
• Have you exceeded limits?
• Are there arrears, defaults or hardship flags?

Consolidating after a run of missed payments doesn’t erase that history, but:

• It can stop further late payments from building up.
• A cleaner structure with fewer accounts is easier to manage and keep current.

If your credit file is messy, consolidation might be part of your clean‑up, but you’ll usually want at least 3–6 months of spotless conduct before lodging a home loan application.

2.3 ATO debts, tax returns and business stability

Tax is a big one for business owners:

• Mainstream lenders prefer you to have no ATO debt, or be on a formal payment plan with several months of on‑time payments.
• Consolidating ATO debt into a home loan is often possible but triggers extra scrutiny of your business performance and tax compliance.

Lenders also expect to see:

• Two years of stable or rising business income under the same ABN for stronger approvals
• All recent tax returns lodged

If you’re behind on tax or relying on unpaid BAS to fund working capital, consolidating debt won’t solve the root problem. That’s a red flag you should fix before you go near a big new mortgage.
