What Is A Second Mortgage?
A second mortgage is a loan secured against a property that already has a mortgage registered against it. The new loan has priority over the first mortgage.
This means that if the property is sold, the first lender is repaid before the second lender receives any money. Because the second lender has less protection, second mortgages are considered higher risk and are usually harder to get approved.
For that reason, most borrowers in Australia choose to refinance their loan or release equity rather than take out a second mortgage.
How Much Can You Borrow With A Second Mortgage In Australia?
- Most lenders cap borrowing at a 60–80% Loan to Value Ratio (LVR). This means your total loans (first and second mortgage combined) usually can’t exceed 60–80% of your property’s value.
- Up to 95% LVR with the same lender (in some cases). If your second mortgage is with your current bank, they may allow a higher total LVR because they control both loans.
- Up to 85% LVR with a different lender. When a second lender is involved, borrowing limits are typically lower due to the increased risk.
- Low doc options are very limited. Most mainstream lenders don’t offer low-doc second mortgages; they are generally available only through private lenders.
- Discounted rates are uncommon. Second mortgages usually carry higher interest rates, and lenders rarely offer the same discounts as on standard home loans.
How Does A Second Mortgage Work When You Already Have A Home Loan?
A second mortgage lets you borrow extra money against your property without replacing your current home loan. Here’s how it usually works:
- You apply for a second mortgage, and the lender assesses your income, equity, and combined Loan-to-Value Ratio (LVR).
- The second lender gives conditional approval based on their higher-risk position behind your existing loan.
- Your current lender is asked to consent, and they may charge a consent or legal processing fee to review the request.
- You keep your existing home loan unchanged, with your lender remaining in first position.
- The second lender registers their mortgage on the property behind the first lender.
- Both loans are secured against the same property, but the first lender has priority if the property is sold.

Why Are Lenders More Cautious About Second Mortgages?
By their very nature, second mortgages are very poor security for a loan compared to a first mortgage.
For example, if you had a mortgage with Westpac for $100,000 secured on your home and you then applied for a $100,000 loan with ANZ, this would be set up as a 2nd mortgage behind the Westpac loan.
In the event that you didn’t pay back your mortgages and the property was sold for $190,000, Westpac would be repaid in full and ANZ would receive whatever was left over.
Because of the complexities of two lenders being involved and the low priority of the debt in the event that you default on your loan, most banks limit the amount you can borrow or refuse to do business with you.
