Quick answer
A second mortgage business loan is registered behind your existing first mortgage and lends against the equity left above it. Your bank loan stays exactly as it is. Alternative second mortgages run between $20k and $5m for business purposes, and no pre-approval valuation is required and interest that can be prepaid or added to the loan.
Key points
- Your existing home or commercial loan stays in place
- Lends against the equity above the first mortgage
- $20,000 to $5,000,000 for business purposes
- No valuation needed before approval; flexible terms
Using equity without touching the bank
Many business owners have built real equity in their home or investment property while paying down a low-cost bank loan. When the business needs money, the bank may say no because of tax debt, credit history or trading history. Refinancing the whole property to a new lender would throw away that cheap loan. A second mortgage solves both problems: it sits behind the existing loan and uses only the equity above it.
How it fits together
| Item | Example (illustrative) |
|---|---|
| Property value | $1,200,000 |
| First mortgage owing | $500,000 |
| Second mortgage for the business | $200,000 |
| Total debt against the property | $700,000 |
| Combined LVR | About 58% |
The lender looks at the combined loan-to-value ratio, the property type and location, and how the business will repay. Try your own figures in the property equity calculator.
Second mortgage or caveat?
A caveat loan is lodged rather than registered and can be in place very quickly, which suits short, urgent needs. A registered second mortgage is more formal and suits longer terms. If the loan ends up running longer, the caveat can be upgraded to a registered second mortgage.
Features that help a business
- No valuation needed before approval, so you are not paying for a report to find out where you stand.
- Interest can be prepaid, or rolled into the loan, keeping monthly cash flow free.
- Flexible terms: hold the loan for as long as the business needs, such as while your file improves enough to refinance.
- Fast: funding in as little as 24 hours on straightforward deals once documents are signed.
Things to consider
A second mortgage puts property on the line, so read the documents carefully and get independent legal advice. Have a clear plan for repayment, whether that is trading income, a future refinance or a sale. If the first mortgage needs consent, allow time for it. Our guide comparing a second mortgage with a refinance covers the trade-offs.
An illustrative use
A wholesale bakery supplying cafes across the city needs a second oven to keep up with demand, has a tax debt from a year of rapid growth, and wants a buffer for wages while new accounts settle in. The owners have a home loan at a low cost with plenty of equity above it.
Refinancing the whole home loan would mean losing that low-cost debt. A second mortgage behind it covers the oven, the tax and the buffer. Interest is added to the balance for the first stretch, so the business carries nothing extra each month while the new oven ramps up. Once trading reflects the growth, the owners plan to consolidate with their bank, and that refinance repays the second mortgage.
Talk to the first lender
Check your existing loan contract for any requirement to seek consent or give notice before a second mortgage is registered. Your solicitor can handle this, but allowing time for it avoids delays.
Check your equity with a real person
Take a minute to enquire with the property address, a rough value and what is owed. Asking involves no credit check, someone experienced reviews it, and nothing gets shared. See what your equity can do.
Frequently asked questions
Does my bank need to approve a second mortgage?
Some first mortgage contracts require the first lender's consent or at least notice before a second mortgage is registered. Your solicitor checks the terms and handles any consent.
How is the amount worked out?
The lender adds the first mortgage balance and the new loan together and compares the total with the property value. The property equity calculator shows how much room there is.
Why not just refinance the first mortgage?
Refinancing can mean losing a low-cost home loan, paying break costs or going through full bank assessment. A second mortgage leaves the cheap debt alone and adds only what the business needs.
Can a second mortgage clear an ATO debt?
Yes. Clearing tax arrears is one of the most common reasons for a business second mortgage.
