Quick answer
Business loans fall into three security groups. Unsecured loans rely on trading and a director's guarantee. Asset-backed finance uses the equipment, vehicle or invoices being funded. Property-backed loans use a home or commercial property through a mortgage or caveat. More security generally allows larger amounts and longer terms at lower cost, but raises what's at stake if the loan isn't repaid.
Key points
- Three groups: unsecured, asset-backed and property-backed.
- More security usually means more money, longer terms, lower cost.
- It also means more at stake if things go wrong.
- A personal guarantee is common even on unsecured loans.
- Unsecured
- Typically $5,000 to $500,000
- Property-backed
- $20,000 to $5,000,000
- Asset-backed
- Sized to the asset or invoices
- Common to all
- Director guarantees are usual
The security behind a loan shapes almost everything else about it: how much you can borrow, how long you get to repay, what it costs and what happens if things go badly. This page sets the three security groups side by side, so you can decide what you’re prepared to put behind the business.
What are the three security groups?
- Unsecured. Nothing specific is mortgaged. The lender relies on trading, credit history and, usually, a director’s personal guarantee.
- Asset-backed. The thing being funded is the security: a vehicle, machine or your unpaid invoices.
- Property-backed. A home or commercial property is used through a first mortgage, second mortgage or caveat.
How do they compare?
| Unsecured | Asset-backed | Property-backed | |
|---|---|---|---|
| Typical size | $5k to $500k | Matched to the asset or ledger | $20k to $5m |
| Term | Shorter | Matched to asset life | Longer |
| Relative cost | Higher | Moderate | Lower pricing, more upfront fees |
| Speed | Often quick | Moderate | Slower, except caveat loans |
| What’s at stake | Guarantee, sometimes business assets | The asset | The property |
| Credit tolerance | Moderate | Moderate | Highest |
When does each make sense?
Unsecured suits a smaller, shorter need when you’d rather not put property on the line, or don’t own any. See unsecured business loans.
Asset-backed suits buying something that holds value, like a vehicle or machine, or funding a sales ledger with reliable customers. See equipment finance and invoice finance.
Property-backed suits larger amounts, longer purposes, weaker credit files, or when repayments need to be lower. See secured business loans.
What does “unsecured” still put at risk?
Unsecured doesn’t mean nothing is at stake:
- Personal guarantees make directors personally liable.
- General security agreements can give a lender rights over business assets.
- Default can lead to legal action and a credit listing.
Our guarantees and security page explains what you’re signing in each case.
How do you decide how much security to offer?
Ask three questions:
- How much do I need, and for how long? Large or long needs point to property.
- What could go wrong? If the business had a bad year, could I keep paying?
- Who else is affected? A family home involves more than the borrower.
Illustrative example. Two Adelaide café owners each need $80,000. One owns her home outright and wants low repayments over five years; a property-backed loan suits her. The other rents and would rather keep his partner’s name off any loan; an unsecured loan over two years with higher repayments suits him better. Both are sensible. The right answer depends on what each is willing to put at stake.
What extra costs come with security?
Property-backed loans add valuation, legal, title search, registration and discharge costs. Asset-backed finance may require comprehensive insurance and PPSR registration. Include these when comparing; see fees.
Who else is affected by the security you offer?
Security decisions rarely affect only the borrower. Before offering property or signing guarantees, think about everyone involved:
- Co-owners of a property. Everyone on the title must agree and sign, and everyone shares the risk.
- A spouse or partner asked to guarantee, even if they’re not involved in the business.
- Family members offering their own property as security.
- Business partners, who may be jointly liable under guarantees.
- Future lenders, who will see existing registrations on the PPSR and title.
| Who | What they should know before signing |
|---|---|
| Co-owner of the property | The property can be sold if the loan isn’t repaid |
| Guarantor spouse | They can be pursued personally for the debt |
| Family member offering security | Their property is at risk; independent advice is essential |
| Business partner | Joint guarantees can make each liable for the whole debt |
Many lenders require third-party guarantors and security providers to get independent legal advice before signing. Even when they don’t insist, it’s wise. A conversation about risk before the loan is far easier than one after a missed payment.
Talk through what you’re comfortable putting forward
It helps to see the options with and without security priced side by side. Asking us won’t touch your credit file; a check only comes up once you decide to proceed. We don’t push your details out to a list of lenders. A real person compares an unsecured, asset-backed and property-backed route for your situation and is plain about the risks of each.
Please be accurate on the form about any property and what’s owed on it. Start your enquiry, or tell the comparison tool whether property is available and then see if you qualify.
Frequently asked questions
Should I use my house as security for a business loan?
It can unlock larger amounts and longer terms, but the home is at risk if the business can't repay. Many owners weigh that against the cost difference and get independent advice before deciding.
What is a general security agreement?
A GSA gives a lender a security interest over some or all of a business's assets, registered on the PPSR. Some unsecured lenders use them. Read the scope carefully.
Can I borrow without a personal guarantee?
It's uncommon for small businesses. Most lenders ask directors to guarantee company borrowing. Some asset-backed or property-backed structures may not need a separate guarantee from everyone.
Can I use someone else's property as security?
A family member can sometimes offer their property as security, but they take on real risk and should get independent legal advice first.
Does security always make a loan cheaper?
Usually the pricing is lower, but security adds valuation, legal and registration costs. On small, short loans those costs can outweigh the saving.
