Quick answer
Choose a secured business loan when you need a larger amount, a longer term or the lowest total cost, and you're comfortable pledging property or equipment. Choose unsecured when the amount is modest, speed matters and you'd rather keep your home out of it. Most unsecured loans still need a director guarantee, so the real decision is which assets you're prepared to put at risk, and for how long.
Key points
- Four questions decide most cases: how much, how long, how fast, and what you're willing to risk
- Unsecured lending is typically sized on turnover and runs from about $5k to $500k; property can support $20k to $5m
- There's a middle ground: loans secured only by the equipment they buy, or by business assets rather than your home
- Unsecured rarely means risk-free, because a director guarantee can still reach personal assets
- You can start unsecured and refinance onto security later, or the reverse, as the business changes
Here’s the decision most owners face. You need money for the business. One lender says yes without touching the house, but the repayments are steep and the term is short. Another offers a lower total cost and a longer term, as long as you let them register a mortgage over your home. Which should you take?
There isn’t a universal right answer, but there is a reliable way to reach yours. It comes down to four questions, a clear view of the in-between options, and an honest look at what happens to you if the business hits a rough patch.

The four questions that settle it
1. How much do you need?
Unsecured lending is sized on your trading. Lenders look at turnover and average deposits, then lend a fraction of that. In practice that usually means somewhere from $5k up to around $500k, with the top end reserved for established businesses with strong statements.
If you need $750k to buy premises or a competitor, unsecured simply won’t stretch. If you need $30k for stock before Christmas, offering property is probably overkill. The unsecured business loan calculator gives a rough sense of what your turnover could support.
2. How long will repayment take?
Match the loan’s life to the life of what it’s paying for. Unsecured loans tend to run from a few months to three years or so. Secured facilities can run much longer, and some property-backed loans are interest-only with the balance repaid from a sale or refinance.
Squeezing a five-year project into a 12-month unsecured loan creates repayments that strain cash flow from week one. Using a 15-year secured loan for a two-month stock gap means paying for time you don’t need, and keeping your property encumbered long after the stock has sold.
3. How quickly do you need it?
Unsecured is usually faster because there’s no valuation, no title search and nothing to register on a land title. Many online lenders approve within a day and fund within two.
Secured loans traditionally take longer, but the gap has narrowed. Some private and caveat lenders can settle in days where the security is clear. Our guide on how caveat loans get approved shows why they can move quickly.
4. What are you prepared to put at risk?
This is the question that matters most and gets discussed least. Write down, honestly, what you’d lose in a worst case under each option:
- Unsecured with a director guarantee: the lender can sue you personally for the shortfall. If you can’t pay a judgment, it can ultimately lead to bankruptcy proceedings, which could reach your home anyway, but through a slower and more contested route.
- Secured over business equipment: the lender can repossess that equipment. Your home isn’t directly in the frame, unless you’ve also signed a guarantee.
- Secured over your home: the lender holds a direct claim on the property and can, after the required steps, take possession and sell it to recover the debt.
If you share the home with a partner who isn’t in the business, their view matters too, and they may need to sign.
The middle ground most owners miss
“Secured or unsecured” sounds like a binary choice. In practice there are several steps between the two, and the right answer often sits in one of them.
| Option | What the lender holds | Typical use |
|---|---|---|
| Unsecured, guarantee only | A director’s personal promise | Smaller, short-term working capital |
| Unsecured with a GSA | A security interest over all company assets, registered on the PPSR | Larger unsecured loans to companies |
| Equipment or vehicle finance | The asset being bought | Machinery, trucks, utes, fit-out items |
| Invoice finance | Your outstanding customer invoices | Businesses with slow-paying trade customers |
| Commercial property security | Premises or land the business or owners hold | Larger, longer facilities |
| Home as security (mortgage or caveat) | Residential property | When the amount or price needs it, or speed via a caveat |
The equipment line is the one people overlook. If you’re buying a $180k excavator, financing it against itself through equipment finance is often cheaper than an unsecured loan and leaves your home completely untouched. Similarly, a business with $400k of debtors on 60-day terms may unlock more through invoice finance than it could ever borrow unsecured.
The second line deserves a word too. A general security agreement lets a lender register an interest over the company’s present and future assets. You might hear it called an “all present and after-acquired property” security. It isn’t the same as a mortgage over your house, but it does mean that loan ranks ahead of unsecured creditors if the company fails. Our glossary entry on the general security agreement explains how it works.
What does each option cost when things go wrong?
Most comparisons stop at the price. It’s worth thinking one step further, because the trouble scenario is when the difference really shows.
If you miss a few payments on an unsecured loan, expect default fees, collection calls and, eventually, a default listing on your credit file and a demand to the guarantors. It’s stressful and damaging, but there’s usually time to negotiate, refinance or set up a hardship arrangement.
If you default on equipment finance, the lender can repossess the asset, sell it and pursue you for any shortfall. You lose the machine, which might also stop you earning.
If you default on a loan secured over property, the consequences are the most serious. After formal notices and the steps the loan contract and state law require, the lender can take possession and sell. Selling under pressure rarely achieves the best price.
None of this is a reason to avoid security. A secured loan you can comfortably afford is far safer than an unsecured loan whose repayments you can’t. The point is to choose the structure with your eyes open, and to borrow an amount that leaves room for a bad quarter. Our guide on how to protect your home when borrowing for business sets out practical safeguards.

Three scenarios, three different answers
These are illustrative examples rather than real cases.
The café that needs $40k fast. A two-year-old café in Hobart needs new refrigeration after the old unit fails in January. Turnover is steady, and the owner rents. Unsecured is the natural fit: the amount is modest, speed matters, and there’s no property to offer. A short term keeps the total cost down, and an early payout option would let her clear it once the busy season ends.
The builder who needs $350k for six months. A Gold Coast builder has two jobs starting and needs working capital until progress claims flow. Unsecured might stretch to part of it, but at a high cost over that size. The director has strong equity in an investment property. A short secured facility over that property, sized to the progress claim schedule, costs far less in total and can be repaid as claims arrive. See business loans against your home for how lenders look at this kind of security.
The transport company buying two prime movers. An established Adelaide freight business wants $420k for two trucks. The owners could offer their home, but there’s no need: the trucks secure themselves under a chattel mortgage, at a cost closer to secured lending than unsecured. Their home stays out of it entirely.
The pattern: the right answer depends far more on the purpose and the timeline than on a general preference for one type.
Where do banks fit in?
Banks are often the cheapest place to borrow, particularly with property security, and if your business fits their criteria a bank offer deserves a serious look. They tend to prefer secured lending and full financials, and they’re generally less comfortable with very short trading histories, recent credit problems or ATO debt.
If your bank has said no, or wants more security than you have, there are well-established alternatives on both sides of the line. Our page on what to do when the bank wants more security than you have walks through them, and the business loans without property page covers unsecured and asset-backed routes.
Can you change your mind later?
Yes, and plenty of owners do. A common path is to start unsecured to move quickly, then refinance onto a secured facility once a valuation is done or the business has a longer track record. Others move the opposite way: they release their home from a mortgage once the business is strong enough to borrow on its own figures.
Two things to check before you plan on switching:
- Early payout terms on the first loan. Some short-term unsecured products charge most of their cost regardless of when you repay. Others only charge interest to the payout date.
- Release costs on the secured loan. Discharging a mortgage or withdrawing a caveat involves a small registry fee and the lender’s discharge charges.
Our deeper explainer on business loan security and guarantees covers how each type of security is registered and released.
Not sure which side of the line you’re on?
Plenty of owners know roughly how much they need but haven’t worked out whether security would change the answer. That’s exactly the conversation we’re set up for: whether you have property, equipment, invoices or simply a solid run of trading.

Frequently asked questions
Is an unsecured business loan really unsecured?
Not in the way most people assume. There's no mortgage or caveat over a named property, but most lenders ask directors for a personal guarantee, and many register a general security interest over the company's assets on the PPSR. If the loan isn't repaid, the lender can pursue the guarantor personally through the courts.
Why are secured business loans cheaper?
Because the lender's loss is limited if things go wrong. With property or equipment it can sell, the lender carries less risk, so it can charge less, lend more and allow longer terms. The total dollar cost on a secured loan is often far lower than on an unsecured loan of the same size.
Can I get a secured business loan without owning a home?
Yes. Equipment and vehicles can secure themselves through equipment finance or a chattel mortgage. Commercial property, vacant land, rural property and outstanding invoices can all act as security. Some lenders will also accept a property owned by a guarantor, such as a family member, though that carries real risk for them.
How much can I borrow unsecured?
It depends mainly on your turnover, how long you've traded and what your bank statements show. As a broad guide, unsecured business lending in Australia typically runs from about $5k up to around $500k, with the larger amounts reserved for established businesses with strong, steady deposits.
Is it faster to get an unsecured loan?
Usually. With no property valuation or title work, many online lenders can approve and fund unsecured loans within a day or two. Secured loans need a valuation, title searches and documents registered against the asset, which often adds days or weeks, although some private and caveat lenders move quickly.
Can I switch from an unsecured to a secured loan later?
Yes, by refinancing. Owners often take a short unsecured loan to act quickly, then refinance onto a cheaper, longer secured facility once a valuation is done or the business has more history. Check the unsecured loan's early payout terms first, because some products charge most of the cost even if repaid early.
