Quick answer
A secured business loan is usually the better choice for larger amounts, longer terms and owners with property equity, because security lets the lender offer more over a longer period. An unsecured loan is better for smaller, shorter needs where speed of setup and keeping property out of it matter more. Most unsecured business loans still need a director guarantee, so they aren't risk-free.
Key points
- Secured lending suits larger amounts and longer terms.
- Unsecured lending suits smaller, shorter needs and is sized on turnover and bank statements.

- RBA data shows the unsecured share of SME credit has stayed below 5% in recent years.
- Larger, longer
- Secured wins
- Smaller, shorter
- Unsecured wins

It’s the first fork in almost every business borrowing decision: put something up as security, or don’t. The answer shapes how much you can borrow, for how long, how much paperwork is involved and what you stand to lose if things go wrong.
How do secured and unsecured loans actually differ?
A secured loan is backed by a specific asset the lender can claim if repayments stop. For business lending that’s most often residential or commercial property, or the vehicle or equipment being bought.
An unsecured loan has no specific asset behind it. The lender assesses your trading, mainly your turnover and bank statements, and almost always asks the directors for a personal guarantee.
Property still dominates. The Reserve Bank’s October 2025 Bulletin on small business conditions notes that the share of SME credit that is unsecured has remained below 5% in recent years, with residential property securing most small business loans, even as lenders report expanding their unsecured offerings.
How do they compare on the five tests?
| Test | Secured | Unsecured |
|---|---|---|
| Security | Property or the asset being bought | Usually a director guarantee only |
| Typical amount | Property-secured: $20,000 to $5,000,000 | Typically $5,000 to $500,000, sized on turnover |
| Term | Longer terms available | Shorter terms |
| Paperwork | Valuation, title and legal steps | Bank statements, ID, business details |
| Repayments | Often monthly | Can be weekly or daily |
| Total cost | Usually lower relative to the amount | Usually higher relative to the amount |
| Biggest risk | The security itself | Personal guarantee and tight repayments |
Our verdict
Our verdict: secured for big and long, unsecured for small and short
- Secured is best for
- Larger amounts, multi-year needs such as buying a business or refinancing, and owners comfortable using property equity.
- Unsecured is best for
- Smaller, defined needs: stock, a hire, a deposit, a short gap, especially for businesses with steady bank deposits and no property to offer.
- Check before you sign
- Total repayable in dollars, repayment frequency, what the guarantee covers, and the costs of discharging any mortgage early.
Secured lending wins on scale and term. If you need a large amount, or the money will be working for years, security lets a lender go further and longer. The cost relative to the amount borrowed is generally lower, and monthly repayments are often gentler on cash flow.
Unsecured lending wins on simplicity and keeping property out of it. No valuation, no mortgage registration, and your home isn’t tied to the business’s fortunes in the same direct way. For a smaller sum with a clear payback, that’s often the right trade.
The middle ground is asset finance: the equipment or vehicle is the security, so property stays out of it but you still get a longer term. See the best way to fund equipment.

Illustrative examples: two owners, two verdicts
Illustrative only.
A landscaping business with three years of trading needs a modest amount for a trailer, tools and a spring stock-up. The owner rents and doesn’t want a long commitment. Verdict: unsecured, with the trailer on asset finance if the lender prefers.
A wholesale distributor wants to buy out a retiring partner, a large sum to be repaid over many years. The remaining owner has substantial equity in her home. Verdict: secured, because the amount and term are beyond what unsecured lending comfortably offers.
What’s the catch with each?
With secured loans: your property is on the line. If the business can’t repay, the lender can recover from the security. There are also setup costs such as valuation and legal fees, and costs to discharge the mortgage when you’re done.
With unsecured loans: the personal guarantee means your personal assets may still be exposed. Repayments can be weekly or daily, which needs careful matching to your cash cycle. And the total cost relative to the amount is usually higher.
Neither is “cheap” or “dear” in the abstract. Run real offers through the total cost comparer and decide on dollars.

Is there a middle path?
Yes, and it’s often overlooked. A few options sit between full property security and nothing at all:
- Asset finance, where the equipment or vehicle being bought is the security.
- A smaller secured facility combined with a smaller unsecured one, so property secures the long-term part and the short-term part stays unsecured.
- Security over business assets rather than personal property, offered by some lenders for some facilities.
Each changes what’s at stake and what you can borrow. If the choice feels like all or nothing, ask about these before deciding.
Which side are you on?

No credit check happens at the enquiry stage, and we keep your details with one specialist rather than spreading them around. The more honestly you describe your trading and security, the more useful the verdict you’ll get back.
Frequently asked questions
What is the difference between a secured and an unsecured business loan?
A secured loan is backed by an asset the lender can claim if you don't repay, commonly property or the equipment being bought. An unsecured loan has no specific asset as security and is assessed mainly on your trading, though a personal guarantee is usually required.
Is an unsecured business loan more expensive?
It often costs more in total relative to the amount borrowed, because the lender carries more risk. Compare actual offers on total cost in dollars rather than assuming.
How much can I borrow unsecured?
Unsecured, cash flow and line-of-credit options for trading businesses typically range from $5,000 to $500,000, sized on turnover and bank statements. Property-secured business loans range from $20,000 to $5,000,000.
What happens if I can't repay a secured loan?
The lender can take steps to recover the debt from the security, which may mean selling the property or asset. That's why secured borrowing should always come with a realistic repayment plan.
Does a personal guarantee make an unsecured loan secured?
Not technically, but it makes you personally responsible for the debt if the business can't pay. In practice, that can put your personal assets at risk, so read the guarantee carefully.
