You’re Putting a Lot on the Line – So Protect It
Buying an existing business can be a shortcut into being your own boss – the customers, systems and income are already there. But if you’re using a secured business loan, you’re not just buying a business. You’re potentially putting your home or other assets on the line as security.
That’s a big call. You’re the one taking the risk, doing the long hours and backing yourself. Here’s a guide to ask the right questions, so you’re not buying a lemon.
Government and small business agencies across Australia all say the same thing: do thorough due diligence before you sign anything. That means carefully checking the financial, legal and operational health of the business so you know what you’re really buying, not just what’s in the sales brochure.
1. Start With Your Own Game Plan, Not the Lender’s Brochure
Before you look at any numbers, get clear on your own goals:
- What kind of lifestyle do you want this business to support?
- How many hours are you willing (or able) to work?
- Are you buying yourself a job, or building something you can grow and eventually sell?
State and federal government guides on buying a business all stress this: does the business actually match your goals and skills?2 A great café on paper might be a nightmare if you hate weekends and public holidays. A trade business might be brilliant if you’re a tradie – or a headache if you’re not.
Once you know what success looks like for you, you’re in a stronger position to walk away from deals that don’t fit – no matter how shiny the sales pitch.
2. Understand What a Secured Business Loan Really Puts at Risk
A secured business loan usually means the lender takes security over:
- Your residential property (family home or investment), and/or
- Business assets like vehicles, equipment, or commercial property.
If the business struggles and you can’t meet repayments, the lender can enforce that security. In plain English: the business might fail, but you still owe the money, and the lender can come after the secured assets.
So before you sign:
- Be crystal clear on what security the lender is taking.
- Stress test your cash flow – what if sales drop 20%? What if rates rise?
- Talk to your accountant and (if using your home) your partner or family about the downside.
We can help you compare business loan options and understand the structure, but you’re the hero here – you decide how much risk you’re willing to carry.
3. Go Deep on the Financials – Not Just Last Month’s Numbers
Due diligence checklists from accountants, banks and government agencies all start with the same core items:
- Profit & loss statements (3–5 years).
- Balance sheets and tax returns.
- BAS statements and GST records.
- Debtors and creditors – who owes the business money and who the business owes.
- Any existing loans or leases attached to the business.
Get your accountant (not the seller’s) to:
- Check whether profits are stable, growing, or patchy.
- Normalise the numbers – remove one-off items so you can see the underlying performance.
- Look for red flags like sudden spikes in revenue, unexplained expenses, or poor record-keeping.
Remember: the lender will look at these numbers too when deciding whether to approve your secured business loan. You want to see what they’ll see – and more.
4. Check the Legal Skeleton: Contracts, Leases, Licences and Liabilities
Legal due diligence is where your lawyer earns their keep. Government and professional guides highlight the importance of reviewing:
- Business structure and ownership – who are you actually buying from? Company? Trust? Sole trader?
- Key contracts – suppliers, major customers, distributors, franchisors.
- Property leases – rent, options to renew, landlord consent to transfer.
- Licences and permits – food safety, liquor, trade licences, council approvals.
- Intellectual property – business name, trademarks, website domain, social media accounts.
- Pending disputes, ATO debts or legal claims.
Your lawyer should also run searches (ASIC, PPSR, ABN, etc.) to confirm the seller actually has the right to sell the business and that you’re not inheriting hidden charges or court actions.
This isn’t just legal box-ticking. If you’re backing the purchase with a secured business loan, unexpected legal or tax problems can smash your cash flow – and put your security at risk.
5. Look Beyond the Numbers: Customers, Suppliers and Staff
Healthy financial statements are great – but you’re buying a living, breathing operation, not just a spreadsheet. Good due diligence digs into the “people side” of the business too.
Questions to work through with your advisors:
- Customers – Is revenue concentrated in a few large clients? What happens if one leaves?
- Suppliers – Are there any exclusive supply agreements or reliance on one key supplier?
- Staff – Who are the key people? Will they stay on after the sale? Are there any underpayment risks or unresolved HR issues?
- Owner dependence – Does everything rely on the current owner’s relationships and know-how, or is there a system you can step into?
If you’re borrowing against your house to buy this business, you want to know whether the income is resilient or fragile. This is where talking to customers, staff and suppliers (with the seller’s okay) can tell you more than any brochure.
6. Stress Test the Business Against Your Loan Repayments
A lot of buyers look at the business and the loan separately. You’re better off viewing them as a single ecosystem: can this business comfortably support a secured business loan, with room for bumps?
With your accountant, map out:
- Projected profit and cash flow for the next 12–24 months.
- Your expected loan repayments (principal + interest) at current rates.
- A “what if” scenario – for example, if revenue drops by 10–20% or costs rise.
If the business only looks okay on paper when everything goes perfectly, that’s a concern. Borrowing against your home or other assets is serious – you want a margin for error.
This is where talking to lenders and brokers about different business loan structures (term loans, equipment finance, working capital) can help you choose a mix that suits the way the business actually runs, not just the purchase price.
7. Build Your “Deal Team” – You Don’t Have to Do This Alone
Every government and professional guide on buying a business says the same thing: don’t try to do all the due diligence on your own.
Your “deal team” might include:
- An accountant to test the financials and tax position.
- A lawyer to review contracts, leases and legal risk.
- A finance broker or lender who understands secured business loans and your industry.
- A trusted mentor or advisor who has bought or run similar businesses before.

Moving Forward With Confidence
Buying a business with a secured business loan can be a powerful way to step up – but it also raises the stakes. You’re tying your personal assets to the future of that business, so it’s worth taking the time to:
- Align the business with your goals and skills.
- Interrogate the financials, not just glance at them.
- Check the legal, tax and operational “plumbing” behind the scenes.
- Stress test the deal against real-world bumps.
- Surround yourself with professionals who’ve done this before.
