Short answer: You can borrow against your equity without touching your existing home loan. A second mortgage sits behind the first, leaving its rate and terms alone. In Victoria a caveat loan can come first, with a registered second mortgage elsewhere. It costs more than a bank loan, so treat it as a fast bridge with a plan to exit.
Why owners do not want to refinance
Refinancing sounds simple: swap your loan for a bigger one and take out the difference as cash. For a business owner in a hurry it usually is not. Here is why many owners decide against it.
- The current loan is good. A competitive rate is worth protecting. If your home loan suits you, replacing it to release cash puts the whole loan at risk to solve one problem.
- Switching costs money. Moneysmart lists the costs that can apply when you switch: a break fee on a fixed-rate loan, a discharge fee when you close the old loan, an application fee on the new one, and in some cases stamp duty or lender’s mortgage insurance.
- It is slow. A new lender assesses the whole file, orders its own valuation and runs its own checks. That is weeks, not days, and the deadline may be this week.
- The full file gets reassessed. Your income, your tax returns, your credit file and your existing debts are all open to question again. If any of those is the reason you need money, they will be in the way.
- The purpose may be a problem. A bank may be reluctant to release equity for a business purpose, or to fund a tax debt, rent arrears or a late payroll.
None of that makes refinancing wrong. It makes it a poor tool for a fast, one-off need. If you are exploring the bigger picture, our guide to unlocking property equity covers all the options side by side.
How a second mortgage sits behind your first
A mortgage is a security interest registered against your title. Your home loan is the first one, and a second mortgage is a separate loan registered behind it. The two are independent contracts with different lenders.
For you, that means three things:
- Your first loan carries on as it is. Same lender, same repayments, same account. Nothing is closed, discharged or renegotiated.
- The new lender sits second in line. If the property were ever sold, the first mortgage is repaid first and the second from what remains. That is why equity, the gap between value and debt, matters so much, and why the lender cares about how the loan is repaid.
- The loan stands alone. It has its own amount, its own term and its own exit. You can repay it without touching the first loan.
A second mortgage from us runs from $20,000 to $5M and can fund in as little as 24 hours. It is assessed on the equity and the exit rather than your financials, so defaults, bad credit and ATO debt are considered. Second mortgages in 24 hours explains what has to be ready on day one.
Top-up, redraw or second mortgage?
Three different tools get called “using your equity”. They behave very differently.
| Bank top-up | Redraw | Second mortgage | |
|---|---|---|---|
| What it is | Your existing loan is increased | You withdraw extra repayments already paid in | A new loan registered behind your first |
| Does the first loan change? | Yes | No, but the balance goes back up | No |
| Speed | Slower, bank reassesses | Quick if available | As little as 24 hours |
| Amount | Set by the bank | Only what you have overpaid | $20,000 to $5M, based on equity and exit |
| Business purpose or tax debt? | May be declined | Not a new credit application, but check your lender’s conditions | Considered |
| Cost | Usually lowest | Cheapest if you have the balance | Higher, priced for speed |
A redraw is a feature of the loan, not a credit assessment, so use it first if you have a balance there. Moneysmart describes it as a feature that gives you access to extra money you have paid into your home loan. Conditions vary by lender, so check yours. Most owners who come to us either do not have a redraw balance or need more than it holds.
Check your first mortgage before you sign
This is the practical step people skip. Your first mortgage is a contract, and it may say something about taking on further security over the same property. We cannot tell you what yours says, because it differs between lenders and between loan types.
Before you sign anything, do these four things:
- Read the loan contract and the mortgage terms. Look for any clause about further charges, further security or consent.
- Ask whether your lender needs notice. If the terms require it, a short call to your lender now is far better than a default notice later.
- Keep the first loan up to date. A second mortgage works best when the first is in good standing. Arrears on the first loan change the picture for everyone.
- Get the payout and balance figures in writing. Equity is calculated from real balances, not estimates.
If your first mortgage already has arrears, tell us in the first conversation. It is solvable in many cases, and it changes how the file is structured. Our bridging loans page covers cases where the plan is to repay from a sale or settlement.
Victoria first: caveat loans, then registered second mortgages
How the loan is secured depends on the state.
- In Victoria, a caveat loan is the fast route. The lender lodges a caveat, which the Victorian Government describes as a document that a person with a legal interest in a property can lodge, and which shows as a note on the title (land.vic.gov.au). It is often used when time is tight, with the plan to replace it with a registered mortgage or repay it. See how a caveat loan works.
- Everywhere else, there is no caveat loan product. The loan settles straight onto a registered second mortgage.
From your side the practical difference is small. You still keep your first mortgage, the lender still looks at the equity and the exit, and the money still arrives quickly. The difference is the paperwork behind it. Our guide on what a caveat loan is and the comparison in caveat loan vs second mortgage go further if you want the detail.
The honest cost trade-off
A second mortgage costs more than a bank’s home loan. That is not a flaw, it is the price of speed, of a loan that is not scored on your financials, and of a lender taking second place on the title. We will not hide that, and you should not accept anyone who does.
So the question is whether the cost is worth what it buys. It is when:
- the cost of waiting is bigger than the cost of the loan, such as a deposit that will be lost, a landlord’s lockout or interest compounding on a tax debt;
- you have a dated plan to repay it, usually by refinancing to a bank once the issue that blocked you is fixed;
- the loan is sized to the need, not to the maximum equity allows.
Think of it as a bridge. You cross it quickly, you do not live on it. Our page on business loan costs explains how fees are structured, and ask for every cost in writing before you sign. If you are comparing options, compare business lenders sets out what to ask each of them.
Plan the exit, and know when refinancing wins
The exit is half of what a lender assesses, so build it first. Write down, in one sentence, how and when this loan gets repaid. Then test it.
- Refinance to a bank. Common when the problem was paperwork. Take a business owner with two unlodged returns who needs to clear a tax debt this week. Once the returns are lodged and the debt is gone, a bank can look at a clean file. The second mortgage has done its job.
- A sale or settlement. If the money comes from selling an asset or a property settling, commercial bridging finance is built for that gap.
- Contract or tender payments. If a large payment is due, the exit is the date it lands. See tender and contract finance.
- Cash flow. Only if the numbers genuinely carry the repayments. Be conservative about it.
Give yourself a margin. If the refinance is planned for month three, assume it could take month four. A lender who sees a realistic buffer in the plan is more comfortable than one shown a perfect timeline.
When refinancing is the better move
A second mortgage is not always the answer, and sometimes the honest advice is to go to the bank.
- You have time. If the need is six weeks away and the file is clean, a bank top-up or refinance will almost certainly cost less.
- Your current rate is poor anyway. If you were already thinking of switching, doing it once, properly, can be cheaper than layering a second loan on top.
- The need is long-term. A multi-year project is better funded with longer, lower-cost bank finance than a loan priced for speed.
- The amount is small and you have a redraw balance. Use your own money first.
For everything else, the combination of speed, no reassessment of your home loan and a lender who looks at equity and exit is precisely what the product is for. See urgent business loans if the clock is already running.

Frequently asked questions
Does a second mortgage change my existing home loan?
No. Your first mortgage stays in place with its own rate, repayments and lender. The new loan is separate and sits behind it. What you must still do is check your loan contract for any clause about further security, which is why we raise it before you sign.
Will my bank find out I have taken a second mortgage?
The second mortgage is registered against the title, so it can be seen by anyone who searches it. Your bank may notice at your next review or refinance. Check your first mortgage terms before proceeding, and speak to your lender if they require notice.
Is a redraw the same as borrowing against equity?
No. A redraw lets you withdraw extra repayments you have already made, so it is your own money coming back. Equity is a different thing: it is the gap between value and debt, and it exists even if you have never made an extra repayment.
How long should I keep a second mortgage?
As short as you sensibly can. It is priced for speed, not for the long haul. Most borrowers plan to refinance to a bank once the reason for the urgency, such as unlodged returns or tax debt, is fixed.
Can I use this if the property is in Victoria?
Yes. In Victoria the loan can be written as a caveat loan, with the lender protected by a caveat on the title. Elsewhere in Australia the loan settles straight onto a registered second mortgage, so the outcome for you is much the same.
Does it cost anything to apply?
No. There's no cost to apply or check your eligibility. All costs are set out in writing in your loan offer before you sign anything.
Will checking my eligibility affect my credit score?
No. Our 60-second eligibility check doesn't make a credit enquiry. A credit check is only done later, with your consent, if you decide to proceed.
