Quick answer
Using home equity for business means borrowing against your home to fund the business, through a refinance, a second mortgage, a caveat loan or a guarantee secured by the home. It can unlock larger amounts, longer terms and lower costs than unsecured finance, and help when trading history or credit is limited. The trade-off is serious: if the business cannot repay, your home is at risk.
Key points
- Home equity can unlock larger amounts and longer terms.
- Options include refinancing, second mortgages and caveat loans.
- Your family home is genuinely at risk if the business fails.
- Independent legal advice is strongly recommended, and often required.
Checklist
- Realistic home value and current mortgage balance
- Usable equity calculated
- Repayment plan from business income
- Exit plan for short-term loans
- Family members informed and advised
- Independent legal advice obtained
For many Australian business owners, the family home is their largest asset and the equity in it is the most powerful source of business funding available. It can turn a decline into an approval, a small facility into a meaningful one, and an expensive short-term loan into a cheaper long-term one. It also ties the business’s fate to the place your family lives. This guide covers both sides honestly.
The ways home equity can fund a business
| Option | How it works | Typical use |
|---|---|---|
| Refinance and top-up | Replace your home loan with a larger one, releasing equity | Long-term business needs |
| Second mortgage | A new mortgage behind your home loan | Medium-term needs without disturbing the first loan |
| Caveat loan | A caveat on title, often short-term and fast | Urgent needs with a clear exit |
| Secured guarantee | A guarantee for a business loan, backed by your house | Company borrowing supported by the director’s property |
Our reviews of second mortgage business loans and caveat loans explain each in detail. Property-secured business loans typically range from $20,000 to $5,000,000.
Why lenders like residential property as security
Residential property is familiar, relatively easy to value and has a broad resale market. That reduces the lender’s risk, which can mean larger amounts, longer terms, lower costs and more flexibility on trading history or credit blemishes.
Working out usable equity
Start with a realistic value, subtract what you owe and apply the lender’s maximum loan-to-value ratio. The difference is your usable equity, which is usually much less than total equity. The property LVR and equity calculator does the arithmetic, and our LVR guide explains how lenders apply it.
The risk, plainly
If the business cannot repay and the problem cannot be fixed, the lender can enforce its security, which can ultimately mean the sale of your home. That risk exists even if it never materialises, and it affects your partner, children and anyone else who lives there. Questions worth asking honestly:
- If the business failed, could we survive the loss of this equity?
- Does everyone on the title understand and agree?
- Is there a cheaper or less risky way to fund this?
Make it safer
- Borrow only what the purpose needs, not the maximum available.
- Keep business borrowing separate from your home loan, with its own repayment plan.
- Set a clear end date and exit plan, especially for short-term loans.
- Get independent legal advice, separately for each owner. Many lenders require it.
- Keep a cash buffer so a slow month does not threaten the home.
- Review regularly and pay down the business portion when you can.
Tax and records
Deductibility of interest generally follows the use of the funds, not what secures them, so interest on the business portion may be deductible. Mixing business and private borrowing in one loan complicates this; keep it separate and keep records. Check the ATO’s deductions guidance and your accountant.
Alternatives to consider first
Before using your home, consider whether equipment finance (secured by the asset), invoice finance (secured by receivables) or an unsecured loan could meet the need. They may cost more but keep the home out of it.
Talking to your family
The home belongs to everyone who lives in it, in a practical sense if not a legal one. Talk openly with your partner about the purpose, the amount, the risk and the plan to repay before approaching a lender. Decisions made together tend to hold up better when times get hard.
An illustrative example
A made-up couple want to expand their bakery into a second site. The fit-out is beyond unsecured limits. They consider a second mortgage over their home, borrowing less than the maximum, with a five-year term and a plan to pay extra from the second site’s profits. Each gets independent legal advice. They proceed, keep a three-month buffer and pay the loan down ahead of schedule as the new site performs.
Questions to ask the lender
- Will the loan be a refinance, a second mortgage, a caveat or a secured guarantee?
- What is the maximum combined LVR, and how will the property be valued?
- Is interest paid monthly, prepaid or added to the loan?
- What happens at the end of the term if the business has not repaid?
- Can the security be released once the loan is reduced or the business is stronger?
Considering using your home?
If you are thinking about using home equity for your business, it helps to understand all the options first. Make one enquiry to explore them. There is no credit check when you first enquire, a real person reviews it and your details go to one lending partner rather than a crowd. Please give an honest property value and what you owe in your enquiry, and tell us if you would prefer to avoid using the home.
Frequently asked questions
How much of my home equity can I use?
Lenders lend up to a maximum loan-to-value ratio across all loans secured on the property. Usable equity is usually much less than total equity. The property LVR and equity calculator gives an estimate.
Is it better to refinance my home loan or take a second mortgage?
A full refinance may be cheaper over the long term but takes longer and replaces your existing loan. A second mortgage or caveat keeps your home loan and can be faster. It depends on cost, timing and how long you need the funds.
Is interest on home equity used for business deductible?
Generally, deductibility follows the use of the funds, so interest on the portion used for business may be deductible. Keep records and confirm with your accountant.
What happens if my business fails?
The lender can enforce its security over your home if the debt is not repaid, which can ultimately mean selling the property. That is why careful thought and advice are essential.
Do co-owners need to agree?
Yes. Everyone on the title must agree to the security, and lenders usually require them to receive independent advice.
Can I limit how much of my home is at risk?
You can borrow less than the maximum, choose a limited guarantee where available, and keep business borrowing in a separate facility with a clear end date.
Can I release my home from the security later?
Often yes, once the business loan is repaid or refinanced, or sometimes when the balance falls and other security is available. Ask how release works before signing.
