Quick answer

Caveat loans and second mortgages let a business borrow against the equity in a property that already has a first mortgage. A second mortgage is registered behind the first lender; a caveat is a faster, short-term interest lodged on the title. Both are used for urgent business needs, with property-secured amounts from $20,000 to $5,000,000 possible, subject to available equity.

Key points

  • Both options use equity above what you owe the first lender.
  • A caveat is typically the fastest property-secured structure, used for short terms.
  • A second mortgage is a registered mortgage that ranks behind your first.
  • Your first lender may need to consent, depending on its mortgage terms.

Many business owners have built significant equity in a home or commercial property, yet their main lender is slow, conservative or simply not set up for urgent business needs. Refinancing the whole mortgage to release equity can take weeks. Caveat loans and second mortgages offer another route: leave the first mortgage exactly where it is and borrow against the equity sitting above it.

These are specialist products. Used well, they solve a short, sharp problem quickly. Used badly — for long-term needs, without an exit — they get expensive. This page explains the difference and how the online process works.

How does borrowing “behind” a first mortgage work?

Say a property is worth $1,200,000 and the first mortgage balance is $600,000 (illustrative figures). The equity is $600,000. A second-ranking lender will set a maximum combined loan-to-value ratio — the total of both loans as a share of the property value — and lend within the gap that leaves.

If the property is ever sold or the loans enforced, the first lender is repaid first, then the second. That ranking is why second-tier lenders price for more risk, and why they care so much about the property’s realistic value and your plan for repayment.

Caveat loan or second mortgage — which fits?

Speed to put in placeTypically the fastestFast, with more steps
Typical termShort — weeks to a few monthsMonths, sometimes longer
Best forUrgent, short needs with a near exitLarger or slightly longer needs
First lender consentNot always requiredMay be required

Both are business-purpose loans. Property-secured amounts from $20,000 to $5,000,000 are possible depending on equity, and speeds such as $20k to $250k possible same day apply only when the title, valuation and documents are all straightforward.

When do businesses use these structures?

  • An ATO garnishee notice or enforcement letter that needs to be resolved quickly — see ATO debt in applications
  • A supplier offering a significant discount for immediate payment on a large order
  • A short gap before a property sale or refinance settles, where full bridging finance isn’t needed
  • A one-off opportunity — stock, equipment or an acquisition — that won’t wait for the main bank
  • Covering a cash crunch while the business restructures debts or collects a large receivable

If the need is ongoing working capital, a second-ranking property loan is usually the wrong tool. A line of credit or a full refinance is often better.

What does the online application look like?

You can begin online in about 60 seconds. The enquiry asks about the amount, the purpose, the property and the existing mortgage. A specialist then calls to confirm:

  1. who owns the property and whether all owners will sign
  2. the current balance and lender on the first mortgage
  3. any other caveats, arrears or interests on the title
  4. the exit — how and when the loan will be repaid

Once a lender is selected, ID is verified, a valuation or desktop assessment is ordered, and title searches are done. Documents are then signed and the caveat or mortgage is lodged. Funds can be paid to you or directly to the creditor, such as the ATO or a supplier.

What questions should you ask before you commit?

  • What is the full cost in dollars for the expected term, including establishment, legal and discharge fees?
  • What happens if repayment is late — default charges, extension fees?
  • Does the first lender need to consent, and who arranges that?
  • Is interest paid monthly or capitalised to the end?
  • Can I repay early without penalty if my exit comes sooner?

Get clear answers in writing. A good specialist will raise these before you have to ask.

What can slow down a caveat or second mortgage?

These products can move quickly, but a few things regularly cause delays. Knowing them in advance lets you deal with them before they hold up funds:

  • Co-owners who aren’t available. Every registered owner typically needs to sign and verify identity. If a co-owner is overseas or unreachable, raise it on the first call.
  • Arrears on the first mortgage. Missed payments on the existing loan are a red flag for second-ranking lenders and need to be explained.
  • Existing caveats on title. Other interests already lodged on the title may need to be dealt with first.
  • Unclear valuation. Unusual properties, rural land or properties needing repair can take longer to value.
  • First lender consent. Where it’s required, the existing lender’s response time is outside everyone’s control.

A specialist who knows these issues will ask about them up front, which is why the enquiry form asks about the existing mortgage and any arrears. Accurate answers there are worth more than speed anywhere else in the process.

Ready to put idle equity to work?

If you have equity in property and a short-term business need that can’t wait, this may be the quickest secured route. Start an online enquiry — there’s no credit check when you enquire, your information stays with one specialist rather than being spread across lenders, and a real person will call to talk through the property and the plan. Accurate figures for the property value and existing balance help us find a lender that can actually proceed on the first try.

Frequently asked questions

What's the main difference between a caveat loan and a second mortgage?

A second mortgage is a registered mortgage that ranks behind the first. A caveat loan relies on a caveat lodged on the title to protect the lender's interest, which can be quicker to put in place and is usually used for shorter terms.

Does my existing lender need to know?

Sometimes. Some first mortgages require the lender's consent before another mortgage is registered. Your specialist will check what applies before documents are issued.

How much can I borrow behind my existing mortgage?

It depends on the property value, the balance owing on the first mortgage and the lender's maximum combined loan-to-value ratio. The equity, not the full property value, sets the ceiling.

Are caveat loans only for emergencies?

They're best suited to short, urgent needs with a clear exit. For longer needs, a second mortgage or refinance is usually more cost-effective.

Can I apply with bad credit or ATO debt?

Yes, these are considered case by case. Property equity and a believable exit plan carry a lot of weight in the assessment.
