Quick answer
It's usually unwise to borrow against your home for a business when the money would cover ongoing losses, when the amount would leave little or no equity cushion, when there is no specific exit, when a co-owner is reluctant, when the amount is small enough for unsecured finance, or when the business may be insolvent. In those cases, fixing the underlying problem or using a different kind of funding is generally safer.
Key points
- Equity can't fix a business that loses money every month.
- No named exit means the loan has no natural end.
- A reluctant co-owner is a warning about the plan, not an obstacle to manage.
- Small amounts rarely justify a mortgage on the title.
- If insolvency is a real possibility, get advice before borrowing more.
A site about second mortgages telling you when not to take one may seem odd. It’s deliberate. A loan that shouldn’t have been written helps nobody: not you, not your family, and not the people who arranged it. Knowing the warning signs also makes it easier to recognise when a second mortgage genuinely is the right call.
Here are the seven situations where we’d usually suggest slowing down or looking elsewhere.
1. Is the money covering losses rather than fixing them?
This is the big one. If the business spends more than it earns each month and nothing specific is about to change that, borrowing against the home buys time but not a solution. Every month the loan runs, the gap keeps growing, and the debt sits on the house rather than the business.
business.gov.au describes poor profitability, including relying on borrowed funds to keep operating and being unable to pay yourself, as a sign of financial trouble. If that sounds familiar, the first job is the business model: pricing, costs, customers. Money may help later, once the leak is fixed.
Instead: work through costs and pricing with your accountant, look at funding from cash flow options such as collecting debtors faster, and consider whether a smaller, temporary facility would bridge the change.
2. Would it leave almost no equity cushion?
If the only way to raise the amount is to push combined LVR (all the debt on the property divided by its value) to the top of what anyone would lend, the plan has no room for error. A lower valuation, a slower sale or a refinance that falls through can all leave you stuck.
Instead: borrow less, use a different property with more equity, or combine a smaller loan with another source. The equity decision helper shows the cushion at different amounts.
3. Is there no specific way out?
“We’ll pay it back when things improve” is not an exit. A second mortgage should be repaid by a named event: a sale, a refinance, or trading profits that already exist. Without one, the loan drifts towards its end date, and extensions get expensive.
Instead: write down an exit and a fallback first. If you can’t, it may be a sign the need is ongoing and needs a longer-term solution. See planning the exit.
4. Is a co-owner signing reluctantly?
If your spouse, partner or a family member co-owns the property and isn’t comfortable, take that seriously. They’re putting their home on the line for a business they may not run. Pressure now can damage more than finances later, and a guarantee or mortgage signed under pressure can create its own problems.
Instead: give them the full picture, offer time and independent legal advice, and be open to their answer being no. See talking it through with a co-owner.
5. Is the amount small?
Property-secured lending starts at $20,000, and every mortgage involves valuation, legal work and registration on the title. For smaller needs, an unsecured or cash-flow facility sized on turnover is usually more proportionate, and it keeps the home out of it.
Instead: compare unsecured business finance.
6. Could the business already be insolvent?
If the company can’t pay its debts as they fall due, directors have serious duties. ASIC’s information sheet on insolvency for directors lists warning signs including continuing losses, cash-flow problems, unpaid creditors and overdue tax or superannuation, and it points to options such as small business restructuring, voluntary administration and safe harbour protections.
Putting the family home behind a company that may be insolvent can turn a company problem into a personal one.
Instead: speak to your accountant or a registered insolvency practitioner before borrowing. The Small Business Debt Helpline, listed on business.gov.au, is another starting point.
7. Are you under pressure to decide today?
Urgency is real. Tax deadlines, settlement dates and supplier terms don’t move. But if someone is pushing you to sign before you’ve understood the costs, the term and the exit, step back. A good second mortgage still makes sense tomorrow.
Instead: ask for the full costs, the term and what happens at maturity in writing. Take the night. Talk to whoever shares the title.
A quick self-check
| Question | If the answer is “yes”… |
|---|---|
| Is the business losing money every month? | Fix the cause before borrowing |
| Would combined LVR sit at the very top of the range? | Borrow less or use another property |
| Is the exit vague? | Define it, with a fallback |
| Is a co-owner unsure? | Pause and give them the full picture |
| Is the need under $20,000? | Look at unsecured options |
| Are creditors and tax going unpaid? | Get insolvency advice first |
None of these is an absolute rule, and real situations are rarely clean. If you’re unsure where you sit, a conversation can help, and you can ask a specialist to look at it without a credit check.
When the answer is still yes
If you’ve worked through this list and none of it really applies, that’s reassuring. It usually means the need is specific, the cushion is reasonable and the exit is real. Read the pros and cons next, then test your numbers.
A straight answer, either way
Send a short enquiry and one specialist will look at it properly. You won’t be credit-checked for asking, your details won’t be shopped around, and if we think a second mortgage is the wrong move, we’ll say so and suggest what might suit better. The more accurately you describe the property, what’s owed, the amount and your exit, the more useful that conversation will be.
Frequently asked questions
Is it wrong to use home equity to save a struggling business?
Not always, but it's risky. If the struggle has a specific cause that the money fixes, such as a one-off tax debt or a delayed payment, it can be sensible. If the business is losing money month after month with no change in sight, borrowing against the home usually deepens the problem.
How do I know if my business might be insolvent?
ASIC lists warning signs such as ongoing losses, poor cash flow, unpaid creditors and overdue tax or super. If several apply, speak to your accountant or a registered insolvency practitioner before taking on more debt.
What should I do instead?
It depends on the reason. For small amounts, consider an unsecured facility. For tax debts, compare an ATO payment plan. For an ongoing shortfall, look hard at costs and pricing first. For growth, consider an investor or a smaller first step.
Can I still enquire if one of these applies?
Yes. A specialist can tell you which option is realistic, and there's no credit check when you first enquire. Sometimes the best outcome of a conversation is a reason not to borrow.
