Quick answer

A secured business loan uses property, usually a home or commercial premises, as security through a first mortgage, second mortgage or caveat. Because the lender's risk is lower, property-backed loans can run from $20,000 to $5,000,000 over longer terms with smaller repayments than unsecured lending. The trade-offs are valuation and legal costs, a slower settlement and the property being at risk if the loan isn't repaid.

Key points

  • Property-backed loans run from $20,000 to $5,000,000.
  • Three main forms: first mortgage, second mortgage and caveat.
  • Longer terms and lower repayments than unsecured, but more upfront cost.
  • Everyone on the property title has to agree and sign.

Putting property behind a business loan changes almost everything about the deal: how much you can borrow, how long you have to repay it, how long it takes to arrange and what’s at stake if things go wrong. This page compares the three main property-backed structures with each other and with unsecured lending, so you can decide whether the trade is worth making.

What counts as a secured business loan?

In everyday use, “secured” means secured by real property. The three common forms are:

  • First mortgage. The lender is first on the title. This usually allows the largest amounts and the longest terms.
  • Second mortgage. Sits behind an existing home loan or first mortgage and relies on the equity left over.
  • Caveat loan. A short-term loan where the lender lodges a caveat on the title instead of a full mortgage. Quick to arrange, built for short periods.

Property-backed business loans through our network run from $20,000 to $5,000,000 over residential or commercial security.

How do the property-backed options compare?

First mortgage Second mortgage Caveat loan Unsecured loan
Position on title First Behind existing loan Caveat lodged None
Usual term Longest Medium Short, often months Short to medium
Speed Slowest Moderate Quickest secured option Often quick
Upfront costs Valuation, legal, registration Similar, plus first lender consent in some cases Legal and establishment Mostly establishment fees
Typical use Large or long-term needs Equity release without refinancing Urgent, short-term gaps Smaller, shorter needs
Main risk Property at risk over a long period Two lenders on one property Cost if it runs past the planned exit Personal guarantee

A caveat loan is not a cheap way to borrow for a long time. It is a bridge with a clear exit, such as a sale settling, a refinance going through or a large invoice being paid. If the exit is uncertain, a longer structure is safer.

When is property security worth it?

Using property tends to make sense when:

  1. The amount is larger than trading alone supports. Unsecured options generally top out around $500,000.
  2. The purpose is long-lived. Buying premises, a large fit-out or a business acquisition shouldn’t sit on a short repayment schedule.
  3. Cash flow can’t carry short-term repayments. A longer term spreads the cost.
  4. Credit history has issues. Strong security can offset a patchy file; see bad credit business loans.

It’s harder to justify when the need is small and short, when the property has little equity, or when the risk to a family home outweighs the saving. Our compare by security page sets these situations out side by side.

What does a lender need for a secured loan?

  • Property address, estimated value and what’s currently owing on it.
  • Consent and signatures from everyone on the title.
  • ID for all borrowers and guarantors.
  • Details of the business and the purpose of the loan.
  • For larger amounts: financial statements, tax returns or an accountant’s letter.
  • A clear exit strategy for short-term loans.

What extra costs come with security?

Secured loans carry costs that unsecured loans often don’t:

  • Valuation of the property.
  • Legal and documentation fees, sometimes for both sides.
  • Title searches and registration of the mortgage or caveat.
  • Discharge fees when the loan is repaid.
  • Lender’s mortgage-style fees or line fees on some products.

These can make a secured loan cost more than expected on a small amount over a short period. Our fees page lists them, and the total cost guide shows how to add them into a fair comparison.

Illustrative example. A Geelong builder needs $350,000 to fund materials and wages on a large commercial job. His turnover supports about half that unsecured. He owns an investment unit with solid equity. A second mortgage over the unit, over three years, provides the full amount with monthly repayments that fit the job’s progress claims. He compares it with a caveat loan, which could settle faster but would need refinancing within months. Because the job runs for 14 months, he picks the second mortgage.

Secured or unsecured: a quick test

Ask yourself three questions:

  • Is the amount more than about $500,000, or more than my turnover would support?
  • Will it take more than two or three years for the purpose to pay for itself?
  • Am I comfortable with the property being at risk for the whole term?

Two “yes” answers to the first questions and a confident “yes” to the third usually point to property. Otherwise, compare unsecured business loans first.

Find out what your property could support

If you’re weighing up whether to use property, a short conversation will tell you a lot. Enquiring doesn’t touch your credit file; a check only comes up once you decide to proceed. We don’t send your details to a pile of lenders. A real person looks at the property, the purpose and the exit, and compares a secured option with the alternatives before you commit to anything.

Please give accurate figures on the form for the property value and what’s owing, so the comparison is grounded from the start. Check your options, or use the comparison tool to rank the loan types first and then send your enquiry.

Frequently asked questions

What's the difference between a first and second mortgage?

A first mortgage is the main loan registered on the title and gets paid first if the property is sold. A second mortgage sits behind an existing first mortgage, so it relies on the equity left over. Second mortgages are usually shorter and cost more because the lender is second in line.

What is a caveat loan?

A caveat loan is a short-term loan where the lender lodges a caveat on the property's title rather than registering a full mortgage. It can be arranged quickly, which suits urgent needs, but it is normally expensive and meant to be repaid or refinanced within months.

Can I use my home to secure a business loan?

Yes, residential property is commonly used. Everyone on the title must agree, and the home is at risk if the business can't repay. Many owners get independent advice before using the family home.

How long does a secured business loan take?

Longer than unsecured, because the property needs to be assessed and security documents prepared and registered. Caveat loans are the quickest form; full first mortgages generally take the longest.

Will I need financials for a secured loan?

It depends on the amount and lender. Some property-backed loans lean heavily on the security and accept lighter documents; larger or longer loans usually want financial statements or tax returns.
