Second Mortgage Loans in Australia
A second mortgage is a loan secured against a property that already has a mortgage on it. The new lender ranks behind the existing one, which is why it is called a second mortgage, and why it is priced and assessed differently to a first. It lets you access the equity in a property without touching, refinancing or breaking your existing loan.
In short: second mortgages are short-term, typically 3 to 24 months. Combined lending across both mortgages commonly reaches 70% to 75% of the property value, occasionally higher on strong metropolitan security. The first mortgagee must consent, which is the single biggest determinant of whether the deal proceeds and how fast. Interest is usually capitalised and repaid at exit.
What we arrange, and what we do not
We arrange second mortgages for business and investment purposes. That covers company and trust borrowers, property investors, developers, and self-employed borrowers releasing equity for a genuine business use.
We do not arrange consumer-purpose second mortgages, meaning borrowing secured over your own home for personal, domestic or household spending. That is not a gap in our panel, it reflects the Australian market. Very few lenders write regulated second mortgages here, the pricing is rarely justifiable for the borrower, and in most cases a better answer exists: increasing your existing loan with your current bank, or a residential bridging loan if the need is short-term and property-related.
If your purpose is personal, we will tell you that at the first conversation rather than at the third. If it is genuinely business or investment, this page is the product.
What is a second mortgage?
When you borrow against property, the lender registers a mortgage on the title. That registration establishes priority. The first registered mortgage is paid out first if the property is ever sold under enforcement. A second mortgage sits behind it and is paid from whatever remains.
That single fact explains everything else about the product:
-
It costs more than a first mortgage, because the lender carries more risk for the same security.
-
The first mortgagee has to agree, or the second cannot be registered on reasonable terms.
-
Combined lending matters more than the second mortgage amount. A $300,000 second behind a $400,000 first on a $1,500,000 property is a modest position. The same $300,000 behind a $1,000,000 first is not.
-
It is short-term by design. Second mortgages solve a timing problem. They are not a facility to sit in for years.
The alternative names you will see are all the same product: second mortgage loan, second mortgage private finance, private second mortgage, or simply a subordinated or ranking loan.
Why most Australian second mortgages are non-consumer
Second mortgage lending in Australia is dominated by private and non-bank lenders funding business and investment purposes. Banks generally will not write a second mortgage behind another lender at all, and the regulated consumer segment is very thin.
The practical consequence is that a business or investment purpose second mortgage is NCCP exempt. The National Consumer Credit Protection Act applies to credit provided predominantly for personal, domestic or household purposes, or to buy or improve residential investment property in some cases. Where the predominant purpose is genuinely business or investment, the responsible lending obligations do not apply.
What that gives you: a far lighter documentation burden, no consumer serviceability assessment, structures such as fully capitalised interest that are routine here, and settlement measured in days rather than weeks.
What it costs you: the lender is not required to assess whether the loan is unsuitable for you. The protections of the National Credit Code do not apply, and external dispute resolution is more limited. You are treated as a commercial party responsible for your own assessment.
That trade is reasonable for an experienced borrower with a clear exit. It is not reasonable if you are being nudged toward a business purpose declaration to get faster money for what is really a personal transaction. Those declarations are taken seriously, and a false one is your problem, not the lender's. The same principle applies across commercial bridging loans.
What a second mortgage is used for
-
Business working capital against property you or your entity already own, without disturbing a well-priced first mortgage.
-
Deposit or acquisition funding for the next property, where the equity is in an existing asset and the timing does not allow a full refinance.
-
Settlement shortfalls, where a first mortgage has been approved but falls short of what completion requires. See covering settlement timing gaps.
-
Construction and development top-up, funding a cost overrun or a stage gap behind an existing senior facility, where the senior lender permits it.
-
Tax and creditor obligations, including a payment arrangement that needs clearing before a refinance can proceed.
-
Renovation or works before sale, where the property will be sold on completion. See renovating before selling.
-
Bridging a refinance, where a new senior lender is committed but weeks away and something needs paying now.
The common thread is that the equity already exists and the exit is already visible. A second mortgage buys you the time between those two facts.
First mortgagee consent and priority deeds
This is the part almost nobody explains, and it is the single most common reason a second mortgage is delayed or falls over. Understand it before you apply and you will save yourself weeks.
Your existing first mortgagee usually holds a term in its loan documents preventing you from granting further security over the property without consent. So the second mortgage lender needs the first mortgagee to formally agree to rank ahead in a defined, capped way. That agreement is documented in a deed of priority, sometimes called a priority deed or a deed of consent.
What the deed does. It fixes the first mortgagee's priority amount, which is the maximum it can claim ahead of the second lender, including its principal, accrued interest, enforcement costs and any future advances. Without a capped priority amount, the second lender has no way of knowing how much sits in front of it, and will not lend.
How long it takes. This is the variable. A private or non-bank first mortgagee will often turn a priority deed around in a few days. A major bank can take two to four weeks, sometimes longer, and will charge a consent fee. Some lenders decline as policy regardless of the numbers.
How to move it faster:
-
Request consent on day one, in parallel with the second mortgage application, not after approval. This is the mistake that costs most deals their timeline.
-
Know your first mortgagee's position. Bank, non-bank or private, and whether they have consented before, changes the realistic timeline enormously.
-
Have the current payout figure ready, so the priority amount can be set without a further round of correspondence.
-
Ask about a caveat as an interim step. Where the first mortgagee will not consent at all, a caveat loan may be the only workable structure. It is less secure for the lender, so it prices higher and the amount available is smaller.
-
If the first mortgagee refuses outright and the numbers are strong, refinancing both positions into a single first mortgage is often faster and cheaper than fighting for consent. We will tell you which of those two roads is shorter before you commit to either.
Combined LVR: how much you can actually release
Second mortgage capacity is set by the combined loan-to-value ratio across both mortgages, not by the size of the second on its own. The formula is: Combined LVR = (first mortgage balance + second mortgage amount) divided by property value
Available equity release = (property value multiplied by maximum combined LVR) minus first mortgage balance
Working ranges in the Australian private market:
-
Up to 65% combined: comfortable. The widest lender choice and the sharpest pricing.
-
65% to 75% combined: the standard band for most second mortgages. Achievable on good security with a clear exit.
-
75% to 80% combined: possible on strong metropolitan residential with a short term and an evidenced exit, priced accordingly.
-
Above 80% combined: rare, and where it exists it usually reflects a contract of sale already exchanged rather than an open-ended position.
A worked illustration. On a $1,200,000 property with a $600,000 first mortgage, a 75% combined ceiling gives $900,000 of total lending, so $300,000 is available as a second mortgage. Lift the first mortgage to $800,000 on the same property and the same ceiling leaves only $100,000.
You can model both positions in the bridging loan calculator.
Worked example
A property investor has an unconditional contract on a second property and needs $400,000 for the deposit and costs. Their existing investment property is well financed at a rate they do not want to lose, and their bank cannot complete a top-up inside the settlement period.
-
Existing investment property value: $1,800,000
-
First mortgage balance: $950,000, an LVR of 52.8%
-
Second mortgage required: $400,000
-
Combined lending at settlement: $1,350,000, a combined LVR of 75.0%
-
Term: 6 months, interest capitalised.
-
Interest at 12% p.a. on $400,000 for 6 months: $24,000.
-
Establishment fee at 2%: $8,000. Legal and documentation including the priority deed: $3,500. Valuation: $1,500. Fees total $13,000.
-
Net advance after costs are deducted at settlement: $387,000.
-
Total cost of funds: $37,000.
-
Repayable at exit: $424,000, taking combined lending to $1,374,000, a combined LVR of 76.3%.
-
Exit: the two properties are refinanced together into a single facility once the new purchase has settled and twelve months of rental history is available.
Rate, LVR and fees depend on the security, the purpose, the combined position, the valuation and the first mortgagee's consent. Second mortgages price above first mortgages because the lender ranks behind.

What a second mortgage costs
Second mortgages carry the same cost categories as any short-term property facility, priced higher to reflect the ranking. Full detail sits on bridging loan costs and fees and bridging loan interest rates.
-
Interest. Charged monthly, usually capitalised into the balance rather than serviced. Priced on combined LVR, security quality, term and the strength of the exit.
-
Establishment fee. Commonly 1% to 2.5% of the facility, deducted at settlement.
-
Legal and documentation. Higher than a first mortgage, because the priority deed has to be negotiated and executed by three parties.
-
First mortgagee consent fee. Charged by your existing lender for granting consent. Varies widely and is easy to forget in your cost estimate.
-
Valuation. Ordered by the second mortgage lender, at your cost.
-
Discharge and registration. Land titles office fees in the relevant state.
The number that matters is the total cost of funds over the actual term, not the headline rate. A higher rate over three months frequently costs less than a lower rate over nine, and a facility that settles in time is worth more than one that does not.
Second mortgage or caveat loan?
Both let you borrow against a property that already carries a mortgage, and they are often discussed as if interchangeable. They are not.
-
Security. A second mortgage is a registered mortgage on title. A caveat is a notice of interest that prevents dealings with the title, but it is not a mortgage and it does not give a power of sale.
-
Consent. A second mortgage generally requires the first mortgagee's consent and a priority deed. A caveat can often be lodged without it.
-
Amount. Second mortgages support larger amounts because the lender's position is stronger. Caveat loans are usually smaller.
-
Speed. A caveat loan can settle in 24 to 72 hours. A second mortgage typically takes longer, driven almost entirely by consent.
-
Cost. Caveat loans price above second mortgages, because the security is weaker.
-
Term. Caveat loans are the shortest facilities in the market, often 1 to 6 months.
The practical rule: if your first mortgagee will consent and you have the time, a second mortgage is the better instrument on every measure except speed. If they will not consent, or the money is needed this week, a caveat loan may be the only option available. More detail in bridging loan versus caveat loan.
Second mortgage or refinance the first?
Before taking a second mortgage, test whether refinancing the first is simply better. It often is.
A second mortgage usually wins when: your first mortgage is at a rate you cannot replace, break costs or fixed rate exit fees are significant, you need the money faster than a refinance can deliver, the requirement is genuinely short-term, or a full refinance would fail current serviceability tests.
Refinancing usually wins when: your first mortgage is not competitively priced anyway, you need the funds for longer than about twelve months, the combined position would sit under a comfortable single-lender LVR, or your first mortgagee will not consent to a second mortgage at all.
Run the arithmetic rather than the instinct. Compare the total cost of the second mortgage over its real term against the break costs plus the rate difference on a refinance. See how to refinance short-term property finance.
Second mortgage lenders in Australia
The panel writing second mortgages here is narrower than most borrowers expect, and it is almost entirely private and non-bank.
-
Major banks will generally not write a second mortgage behind another lender. They will consider increasing their own first mortgage instead.
-
Non-bank lenders write second mortgages selectively, usually with tighter combined LVR ceilings and standard documentation.
-
Private lenders are the core of this market. They price on the asset, the combined position and the exit, they move quickly, and they will consider situations the others will not.
-
Specialist and family office funders take larger and more unusual positions, including development-related second mortgages behind a senior facility.
Because the panel is narrow and each lender's appetite differs sharply by state, security type and combined LVR, the difference between the right lender and the wrong one is measured in weeks and in whole percentage points. That matching is what we do. See about us and what to do if you have been declined.
How fast can a second mortgage settle?
Where the first mortgagee is a private or non-bank lender and consent is straightforward, 3 to 7 business days is realistic. Where the first mortgagee is a major bank, 2 to 4 weeks is more likely, and the consent process is almost always the whole of the delay.
What slows a second mortgage down, in order of frequency:
-
First mortgagee consent requested too late, or not requested until after credit approval.
-
The priority amount cannot be agreed, usually because the first mortgagee wants headroom for future advances that the second lender will not accept.
-
Valuation comes in below expectation, pushing the combined LVR past the ceiling and forcing the amount down.
-
The exit is asserted rather than evidenced. "We will refinance" is not an exit. A conditional approval, a signed contract or a listing with comparable evidence is.
-
Purpose is unclear. If the business or investment purpose is not documented properly, the file has to be reassessed against a different framework entirely.
Read more on why the exit drives everything in bridging loan exit strategies.
What you will need
-
Property address, current value or a recent valuation, and rates notice
-
Current first mortgage lender, balance and payout figure
-
Amount required and a clear statement of purpose
-
Evidence of the exit: contract of sale, refinance approval, project timeline or receivable
-
Entity details if borrowing through a company or trust, including the trust deed
-
Identification for all directors, trustees and guarantors
Financial statements are usually not required for a business purpose second mortgage. The security, the combined position and the exit carry the assessment. See eligibility and self-employed borrowers.
Frequently asked questions
What is a second mortgage?
A second mortgage is a loan secured against a property that already has a mortgage registered on it. The second lender ranks behind the first, so if the property were sold under enforcement the first mortgage is repaid before anything flows to the second. That ranking is why second mortgages price higher than first mortgages and why the first mortgagee's consent is required.
Do I need my current lender's permission for a second mortgage?
In almost all cases, yes. Most first mortgage documents prohibit granting further security without consent, and the second lender needs a deed of priority that caps how much the first mortgagee can claim ahead of it. Private and non-bank first mortgagees often consent within days. Major banks commonly take two to four weeks and charge a consent fee. Some decline as policy.
How much can I borrow on a second mortgage?
Capacity is set by combined loan-to-value ratio across both mortgages, typically capped at 70% to 75% of the property value, occasionally to 80% on strong metropolitan security with a short term. Subtract your first mortgage balance from that ceiling to find what is available. On a $1,200,000 property with a $600,000 first mortgage and a 75% ceiling, that is $300,000.
What are second mortgage rates in Australia?
Second mortgages price above first mortgages because the lender ranks behind. The rate depends on combined LVR, security type and location, term, and how well the exit is evidenced. A 65% combined position on metropolitan residential with a signed contract prices very differently to a 78% position on regional land with an intended refinance. Ask for a total cost of funds figure over your actual term rather than comparing headline rates.
Can I get a second mortgage for business purposes?
Yes, and that is the majority of the Australian second mortgage market. Where the predominant purpose is genuinely business or investment, the loan sits outside the NCCP framework, which allows lighter documentation and faster settlement. The purpose must be genuine and properly documented.
Do you arrange second mortgages on an owner-occupied home for personal use?
No. We arrange second mortgages for business and investment purposes. Consumer-purpose second mortgage lending in Australia is a very thin market and the pricing rarely works in the borrower's favour. If your need is personal and short-term, a residential bridging loan or an increase with your existing lender is usually the better answer, and we will say so.
How quickly can a second mortgage settle?
Three to seven business days where the first mortgagee is private or non-bank and consent moves quickly. Two to four weeks where the first mortgagee is a major bank. The consent and priority deed process is almost always the critical path, so it should be started on day one rather than after approval.
What is a deed of priority?
A tripartite agreement between you, your first mortgagee and your second mortgagee that fixes the maximum amount the first mortgagee can claim ahead of the second, covering principal, accrued interest, costs and any future advances. Without it the second lender cannot quantify the debt sitting in front of it, and will not proceed.
Is a second mortgage the same as a caveat loan?
No. A second mortgage is registered on title and carries a power of sale. A caveat only prevents dealings with the title and is a weaker security. Caveat loans settle faster and often need no consent, but they are smaller, shorter and more expensive. Where consent is achievable and there is time, a second mortgage is the better instrument.
Can I get a second mortgage for construction?
Yes, where a senior construction facility is already in place and permits it, and where the second position sits within an acceptable combined LVR against the as-is value rather than the completed value. It is commonly used for cost overruns and stage gaps. Broader development finance is covered under commercial bridging loans and bridging loans for developers.
What happens if I cannot repay at the end of the term?
Speak to the lender well before the expiry date. Extensions are common where the exit is progressing and simply slower than expected, and are usually granted for a fee plus continued interest. Leaving it to expiry with no contact is what triggers default interest and enforcement. This is why an evidenced exit matters more than any other part of the application.
Can a company or trust take a second mortgage?
Yes. Company and trust borrowers are standard in this market. You will need the constitution or trust deed, director and trustee identification, and personal guarantees are typically required.
