Our verdict Often, yes
The short answer
Often, yes. If your home has equity above what's owed on the existing mortgage, a business loan can be secured behind it — commonly as a second mortgage or a caveat — without refinancing your home loan. The lender assesses the remaining equity, the business purpose and how you'll repay. Your first mortgage lender's consent may be needed depending on the loan type and their terms.
Key points
- A second mortgage or caveat can sit behind your existing home loan — no need to refinance it.
- The lender looks at the equity left after the first mortgage.
- Your existing home loan stays in place, with its own repayments.
- Check your home loan terms — some first mortgage lenders need to consent to a second mortgage.
Can my home help my business even with a home loan on it?
Very often, yes. This is one of the most common situations we see.
Most business owners who own a home still have a mortgage on it. But after years of repayments and rising values, many have a lot of equity — the gap between what the home is worth and what’s owed. That equity can secure a business loan without touching your existing home loan.
The RBA’s October 2025 Bulletin noted that most SME lending in Australia is secured, much of it by residential property. Using the family home for the business is how a great many Australian businesses are funded.
How does a loan sit behind my existing mortgage?
Think of your property title as a queue.
| Position | Who | What it means |
|---|---|---|
| First | Your home loan lender | Paid first if the property is ever sold |
| Second | Your business lender (second mortgage) | Paid from what’s left after the first |
| Caveat | A lender with a registered interest | Notice on title that stops dealings without their involvement |
Property-secured business loans — $20,000 to $5,000,000 through first mortgages, second mortgages and caveat loans over residential or commercial property — can take either the second-mortgage or caveat position when a first mortgage already exists. Your home loan stays exactly as it is.
Land Use Victoria describes a caveat as a document lodged by someone with a legal interest in a property, which puts a note on the title telling others that a third party might have rights over it. Caveat loans tend to suit shorter-term needs, while second mortgages suit a broader range.
What does the lender assess?
- Available equity. The property’s value, less what’s owed on the first mortgage.
- Property type and location. Some are easier to lend against than others.
- Purpose. A genuine business use.
- Repayment plan. From trading, a refinance or an asset sale.
- Your existing commitments. Your home loan repayments are part of the picture.
Credit history and time in business still count, but equity and a sensible plan carry most of the weight. That’s why this route works for new businesses too — see three months trading.

Do I need my bank’s permission?
Sometimes. Some home loan contracts require the first mortgage lender to consent before a second mortgage is registered. Others don’t. Check your loan documents or ask your bank. We’ll talk through what applies to your situation on the call.
Why not just top up my home loan?
Sometimes that’s the right answer — if your bank will do it and the purpose fits. But business owners often find:
- the bank won’t top up for business purposes without full business financials;
- the business doesn’t yet meet the bank’s criteria;
- timing matters and the bank process is slow;
- they’d rather keep business debt separate from the home loan.
A separate business loan behind the home loan avoids refinancing, and keeps the business debt distinct.
An illustrative example
Illustrative only; no real people or business.
A dental technician runs a small lab. She wants $140,000 for a digital milling machine and scanner. Her home is worth around $950,000 and has $420,000 owing on the home loan.
- Her bank won’t top up her home loan because her lab’s latest return shows a loss after a big depreciation claim.
- A second mortgage behind her home loan funds the equipment, assessed on the remaining equity and the lab’s steady bank statements.
- Her home loan repayments don’t change. The plan is to refinance the business loan once the new equipment lifts the lab’s figures.
What should I think about first?
Your home is at stake if the business loan isn’t repaid. Be clear on the purpose, the repayment plan and what you’d do if trade slowed. If a partner co-owns the home, see using a partner’s property. If you already have several business loans, already have loans explains how consolidation can work.
Second mortgage or caveat — which suits me?
Both are ways a business loan can sit behind your existing home loan. Which fits depends on your purpose and timeline.
| Second mortgage | Caveat loan | |
|---|---|---|
| How it’s recorded | Registered mortgage on title, behind the first | A caveat lodged on title |
| Typical use | Broader range of terms and purposes | Often shorter-term needs |
| First lender’s consent | May be needed, depending on your home loan terms | Depends on the circumstances |
| Paperwork | Mortgage documents registered with the land titles office | Caveat lodged with the land titles office |
A real person will explain which option suits your situation and why, in plain English, before you commit to anything. Neither changes your existing home loan or its repayments.
Whichever route fits, the same questions apply: how much equity is there, what’s the money for and how will it be repaid? If a partner co-owns the home, see partner’s property. If your equity is in business premises instead, read commercial property. And if you’re asset-rich but income-light on paper, equity with low income is worth a look.
Let’s look at your equity
Your home’s equity can be a powerful way to fund growth — used carefully, with a clear plan.
When you enquire, there’s no credit check, and your details stay with one person rather than being pushed out to a stack of lenders. A real person reads your situation and calls you. Please be accurate on the form about your home’s approximate value and what’s owed, so the first answer you get is the right one. See if you qualify.
Frequently asked questions
What's the difference between a second mortgage and a caveat loan?
A second mortgage is registered on the title behind your first mortgage. A caveat is a notice on the title that the lender has an interest in the property. Caveat loans are often used for shorter-term needs; both are types of property-secured lending.
Do I have to tell my home loan lender?
Sometimes. Some first mortgage lenders require their consent before a second mortgage is registered. Your existing loan contract will say, and we can talk it through.
Will a business loan change my home loan?
No. Your home loan stays exactly as it is, with its own repayments. The business loan is separate, with its own terms and repayments.
How much equity do I need?
Enough that, after the first mortgage, there's a meaningful buffer for the lender. The exact amount depends on the property, its location and the lender. A real person can give you a realistic view once they know the details.
What if the home is jointly owned?
Every owner on the title needs to agree and sign. If a co-owner isn't involved in the business, they'll usually be asked to get independent advice.
