If you own property in Australia and have built up equity, you can potentially use that equity to fund business activity at home loan interest rates — which are typically 3–4 times cheaper than unsecured business loans. But putting your family home on the line for a business venture carries real risk, and the structure matters for tax purposes too.
How Home Equity Business Lending Works
There are two main ways to access home equity for business:
1. Refinance with Cash-Out
You refinance your existing home loan for a higher amount and take the difference as cash. You then use those funds for your business. The loan is secured against the property and charged at home loan rates.
2. Home Equity Line of Credit (HELOC)
A line of credit secured against your property up to a set limit. You draw funds as needed and only pay interest on what you've drawn. This suits businesses that need flexible access to capital over time.
3. Split Loan Structure
Your lender splits the mortgage into a personal portion (home) and a business portion. This makes it easier to track tax deductibility, as only the business portion's interest is deductible.
Rate Comparison: Equity vs Unsecured
| Finance Type | Typical Rate | $200K over 5 years: Total Interest |
|---|---|---|
| Unsecured business loan | 15–30% p.a. | ~$85,000–$200,000 |
| Home equity (variable) | 6.0–7.0% p.a. | ~$33,000–$40,000 |
| Commercial property loan | 7.0–8.5% p.a. | ~$40,000–$50,000 |
The cost saving is dramatic. A $200,000 business investment funded through home equity rather than an unsecured lender could save $50,000–$160,000 in interest over 5 years.
The Risks of Using Home Equity for Business
The fundamental risk: If your business fails and you can't service the debt, the lender can enforce against your home. You're not just risking the business — you're risking where your family lives. This is the decision that requires the most careful thought.
- Property at risk: Business failure can mean losing your home
- Personal tax complications: Mixing business and personal debt requires careful record-keeping
- Impacts home loan refinancing later: Higher LVR may limit future refinancing options
- Partner/spouse exposure: If property is jointly owned, your partner is also exposed
Tax Considerations
This is where structure matters enormously. Interest on funds used for income-producing business purposes is generally tax-deductible. But:
- If the funds are mixed with personal use, only the business-use portion is deductible
- The ATO requires you to demonstrate a clear nexus between the borrowed funds and the business activity
- A split loan structure is strongly recommended to keep clear records
- Consult your accountant before drawing — the deductibility rules can be complex
When It Makes Sense
- Established business with stable cash flow — risk of default is low
- You have substantial equity (LVR will still be below 80% after the drawdown)
- The business investment has a clear, measurable return
- The cost saving over unsecured finance is material to the venture's success
When to Avoid It
- New or unproven business with uncertain cash flow
- Business is in a high-risk industry or early stage
- You can access other secured business finance at reasonable rates
- Your home is your only significant asset
Frequently Asked Questions
Generally yes, if the funds are used for business purposes and you maintain clear records. A split loan structure makes it easier to track and demonstrate to the ATO. Always confirm with your accountant before drawing.
Most lenders allow you to access equity up to 80% LVR without LMI. On a $1M property with a $400,000 mortgage, you could potentially access up to $400,000 in equity (bringing the loan to $800,000). Above 80% LVR, lenders mortgage insurance applies.
Yes — lenders ask about the purpose of equity access. Some lenders have restrictions on using residential equity for business purposes. A broker can identify lenders whose policies support this structure.
The home loan repayment obligation doesn't change if the business fails. If you can't service the debt, the lender can eventually enforce against the property. This is the core risk — and it must be factored into the decision.
Yes — if you own an investment property, using that as security for business finance protects the family home. Commercial property loans or equipment finance secured against business assets are also options that don't put your residence at risk.
