The short answer
If your first lender will consent, a registered second mortgage is usually the cheaper and more secure way to borrow against your equity. If consent is slow, refused, or simply won’t arrive before your deadline, a caveat loan can fund faster, but it costs more, runs for a shorter term, and only works when your exit is certain.
This guide is for business owners, investors and developers who already have a first mortgage and need funds without refinancing it. It covers whether banks allow second mortgages, how first mortgagee consent works in each state, and how to choose between the two structures. If you already know you want a registered second-ranking loan, see our second mortgage loans page.
Do banks allow second mortgages?
Some do, but many mainstream lenders are reluctant to lend in second position, and those that do tend to add strict conditions, higher fees or a lower loan limit. That is why most second-ranking loans in Australia come from private lenders, family offices and specialist non-bank lenders.
The more important question is usually a different one: will your existing lender allow a second mortgage behind it? Most first mortgage contracts include a clause, often called a negative pledge, that says you can’t give another lender security over the property without consent. Even where the land registry lets a second mortgage through, breaching that clause can put your first loan in default.
When you ask your first lender for consent, expect three things:
- An administration fee for processing the request.
- A deed of priority, which sets out how much the first lender can recover ahead of the second lender.
- Time. Consent sits in a bank’s back-office queue, and it is the step most likely to slow a second mortgage down.
How first mortgagee consent works in each state
Whether the land registry needs your first lender’s involvement depends on where the property is. Whether your first loan contract allows a second mortgage is a separate question, and it applies in every state.
| State | Can the second mortgage be registered without the first lender? | What it means in practice |
|---|---|---|
| Victoria | No. The first lender usually controls the electronic certificate of title and has to nominate it into the PEXA workspace. | Your first lender will know about the second mortgage. Because its loan terms usually treat an unapproved second mortgage as a default, consent and a deed of priority are normally negotiated up front. |
| New South Wales | Yes, since paper titles and the Control of the Right to Deal framework were abolished on 11 October 2021. | Nothing blocks lodgement, but a negative pledge in your first loan can still make the second mortgage a default. |
| Queensland | Yes. | Queensland law limits a first lender’s ability to restrict or default you for a second mortgage, but check your contract with a lawyer. |
| South Australia and ACT | Yes, lodged electronically through PEXA. | As in NSW, your first loan contract may still require consent. |
| Other states and territories | Depends on whether a paper title is still on issue. | If one is, the first lender may need to produce it, so its cooperation is needed. |

Why lenders still ask for consent when the law doesn’t require it
Until your first lender receives written notice of the second mortgage, any further money it advances to you can rank ahead of the second lender. This is known as tacking. In NSW, registering the second mortgage on its own is not treated as sufficient notice, but a written consent from the first lender is. So even where consent is optional, many second mortgage lenders still ask for it, along with a deed of priority that caps the first lender’s priority amount.
What is a caveat loan?
A caveat loan is a short-term loan where the lender protects its interest by lodging a caveat on your property’s title instead of registering a mortgage. The caveat is a formal notice that someone claims an interest in the property. While it stands, you can’t sell, refinance or give further security over the property without dealing with the lender’s claim.
The loan itself usually rests on the loan agreement plus an unregistered mortgage or charge. Because nothing new is registered as a mortgage, some caveat structures don’t need the first lender’s consent. That is the main reason borrowers use them: they can settle when a bank won’t consent, or won’t respond in time.
The trade-off is weaker security for the lender. A registered mortgagee has a statutory power of sale if you default. A caveat lender doesn’t, and generally has to go to court to enforce. Lenders price that risk in, so caveat loans typically:
- run for one to twelve months, tied to a specific repayment event;
- cost more than a registered second mortgage in interest and fees;
- be sized conservatively, leaving a buffer in the equity left after your first mortgage.
Many borrowers treat a caveat loan as a bridge: fund quickly now, then refinance into a registered second mortgage once consent or paperwork is in place.
Second mortgage vs caveat loan at a glance
| Registered second mortgage | Caveat loan | |
|---|---|---|
| How the lender is secured | Mortgage registered on title, ranking behind the first | Caveat lodged over an unregistered mortgage or charge |
| First lender’s consent | Usually sought; needed in practice in Victoria | Often not needed, depending on the structure |
| Speed | Days to a few weeks; consent is the usual bottleneck | Can settle faster when consent isn’t needed |
| Typical term | 3 to 24 months for the facilities we arrange | Usually 1 to 12 months |
| Cost | Higher than a first mortgage; from 15% p.a. through Formation Finance | Generally higher again than a registered second mortgage |
| Lender’s enforcement | Statutory power of sale, subject to the first mortgage | No direct power of sale; enforcement usually goes through court |
| Your first loan | Consent and a deed of priority keep you compliant | Check your contract: many prohibit any further security, not just registered mortgages |
| Best for | Planned funding where there’s time to get consent | Urgent, short-term needs with a certain exit |
Which one fits your situation?
Start with two questions: how soon do you need the money, and how certain is your way out?
A registered second mortgage usually fits when:
- you have two to three weeks, and your first lender is likely to consent;
- you need the funds for more than a few months;
- you want to leave a low or fixed-rate first loan untouched. Breaking a fixed rate can trigger break costs, and a second mortgage avoids that. Case study 2 on our second mortgage page shows how this works.
A caveat loan may fit when:
- your first lender has refused consent, or won’t respond before your deadline;
- the need is urgent, such as an ATO debt at the enforcement stage, a settlement date, or a builder’s progress claim;
- you have a clear, dated exit within months, such as a property sale, a construction loan drawdown or a refinance that is already approved.
Neither may be right when:
- the exit depends on something that might not happen, such as a sale with no buyer or a refinance not yet applied for;
- the combined debt would push you close to the full value of the property. Most second-ranking lenders cap combined borrowing at around 70% to 75% of the property’s value;
- a full refinance, a sale of another asset or a payment arrangement would cost less overall.
Costs and risks to budget for
Interest is only part of the cost. With either structure, budget for:
- interest, paid monthly or capitalised into the loan;
- an establishment fee, usually a percentage of the loan;
- valuation fees;
- legal fees for both you and the lender;
- the first lender’s consent fee and deed of priority costs, for a second mortgage;
- discharge fees, plus extension fees if the exit runs late.
A worked example. A property is valued at $1,500,000 with $700,000 owing on the first mortgage. At a 75% combined LVR, total borrowing can reach $1,125,000, which leaves up to $425,000 for a second mortgage. Borrowing $300,000 for 12 months at 15% p.a. interest-only costs $3,750 a month, or $45,000 over the year. Our calculator’s example adds an establishment fee of $7,500 (2.5%), before valuation and legal costs. You can run your own numbers in the second mortgage loans calculator.
The main risks to weigh:
- Exit risk. If the sale or refinance you’re counting on doesn’t happen by maturity, extension fees and default interest add up quickly, and the lender may move to sell.
- Default on your first loan. A second mortgage or caveat loan taken without the consent your first loan contract requires can put that loan in default.
- Your home as security. Business-purpose loans can be secured over your home. The National Credit Code applies to credit for personal, domestic or household purposes, so most of its protections won’t apply to a business-purpose loan. Get independent legal and financial advice before you sign.
Frequently asked questions
Do I need my bank’s permission to get a second mortgage?
It depends on your state and your loan contract. In Victoria, your first lender is involved because it controls the electronic title. In NSW, Queensland, South Australia and the ACT, the second mortgage can usually be registered without it, but most first loan contracts still require consent.
Will my bank find out about a second mortgage?
Assume it will. In Victoria it has to take part in the electronic settlement. Elsewhere, the mortgage appears on the title, and second lenders usually notify the first lender in writing to protect their priority.
Is a caveat loan riskier than a second mortgage?
For you, mainly in cost and timing: higher rates and fees, and a shorter term that leaves less room if your exit slips. For the lender, the security is weaker because it has no direct power of sale, which is why caveat loans are priced higher.
Can I refinance a caveat loan into a second mortgage?
Yes. Many borrowers use a caveat loan to meet an urgent deadline, then move to a registered second mortgage once consent and documents are in place. Plan that refinance before you take the caveat loan, not after.
How quickly can each one settle?
Through our lender panel, second mortgages typically settle in 7 to 14 business days once the valuation and documents are received. A caveat loan can be faster when no consent is needed, but timing still depends on the lender, valuation and legal work.
