Second Mortgage Behind the Bank: the FY27 Shift
Releasing equity behind an existing bank loan used to mean asking the bank and little else. For self-employed owners heading into FY27, the funders who write a second mortgage have changed, and so has what they look at first.
Quick Answer
A second mortgage sits behind your existing bank loan as a registered second, so you can release equity without resetting the first. For self-employed owners, non-bank and private funders now write most of them, and approval turns on first mortgagee consent and a credible exit.
The Bank Will Not Always Block a Second Mortgage
Many owners assume a bank will never let another lender register behind it, so they rule out a second mortgage before they start. In reality a second mortgage registered second behind a bank first mortgage is common, and the bank's position is protected by priority rather than by blocking the loan outright.
What actually stands between you and the funds is consent. First mortgagee consent is the gating step, the written agreement of the existing lender to sit a new security behind it. The rate matters, but it is the second question, not the first.
What Lenders Actually Look At First
From the funder's side, the first read is not the rate, it is the exit and the equity behind the senior. What lenders actually look at first is whether there is a credible, identifiable exit and enough equity sitting behind the bank's first mortgage to price a second safely (illustrative, varies by lender). The first thing I read on one of these files is the exit, then the equity, then everything else.
Stronger Fit
- Clear equity sitting behind the bank's senior debt
- A credible, dated exit such as a sale, a refinance, or a settling contract
- A first mortgagee likely to consent to a second behind it
- A short, defined purpose with a clear end date
Gets Tricky
- The senior already sitting at a high LVR ceiling (illustrative, varies by lender)
- No identifiable exit, or an exit that depends on a single uncertain event
- A first mortgagee that refuses consent for a second
- A purpose that stretches well beyond a short term
Read in that order, most second mortgage decisions come down to the exit and the equity, not the borrower's payslip, which is exactly why the structure suits self-employed owners whose income does not fit a bank's servicing box.
Why the Second Mortgage Has Moved to Non-Bank Seniors
The second mortgage has moved toward non-bank seniors because bank servicing tests and macroprudential limits keep pushing higher-DTI, self-employed borrowers out of the major banks. Non-bank seniors tend to consent more readily (varies by lender) and price the second above the senior to reflect the second-ranking risk (illustrative, varies by lender). A second mortgage can act as a high-DTI buffer, letting an owner release equity without re-testing the whole position against a bank's servicing model.
Since the APRA debt-to-income limit took effect on 1 February 2026, higher-DTI borrowers have been steered further toward non-bank and private lending options. The policy backdrop is shifting too. From 13 July 2026, non-bank lender product data becomes shareable under the Consumer Data Right, the product-data switch-on, with consumer data sharing in the sector following from 9 November 2026. For a borrower, that means clearer product comparison first, with the ability to share your own data into a non-bank lender arriving later, not on the July date.
Setting Up a Second Mortgage for an FY27 Move
Setting up a second mortgage for an FY27 property move starts with the exit, then the consent, then the equity release. The aim is a registered second that releases equity without resetting the senior, on a short term matched to a credible, identifiable exit strategy (illustrative, varies by lender). Get those three in order and the rest of the file tends to follow.
This is one lane in a wider property finance stack, and it tends to suit owners who have the equity and the asset story but need the bank's senior left alone while they move.
For self-employed owners planning FY27 property moves, a second mortgage is less about the bank's permission than about the exit, the equity behind the senior, and first mortgagee consent. The funders have shifted to non-bank seniors, and the product-data switch-on under the CDR will make comparison clearer well before any borrower can share their own data into a non-bank lender. Set the exit first, confirm consent, then release the equity without resetting the senior.
Key takeaway: A second mortgage works best when a credible, identifiable exit is set before the loan, not after.Frequently Asked Questions
Registering a second mortgage in Australia almost always needs the first mortgagee's written consent, because the existing lender controls the priority of any security registered behind it. The consent step is the gating point, not the rate, and a non-bank first mortgagee will often consent more readily than a major bank (this varies by lender). You can see how the structure is set up in our guide to how a second mortgage works.
A second mortgage is a loan registered behind your existing first mortgage, so it draws on the equity sitting behind the senior loan without replacing it. It ranks second for repayment if the property is sold, which is why it is priced above the senior (illustrative, varies by lender). Our second mortgage page sets out where it fits for self-employed owners.
When a major bank will not write a second mortgage, non-bank seniors and private lending funders usually will, pricing the loan to reflect the second-ranking risk. These funders read the deal on equity and exit rather than a standard servicing model, which suits self-employed owners with strong assets but variable income. The trade is a higher cost than a bank first mortgage (illustrative, varies by lender).
The cost of a second mortgage is set above the rate on the first mortgage, because the funder ranks behind the bank and carries more risk (illustrative, varies by lender). Pricing depends on the equity behind the senior, the term, and the strength of the exit, so there is no single rate. Our second mortgage rates guide explains what moves the number.
A second mortgage and a caveat loan solve different problems: a second mortgage registers a security behind the bank to release equity over a short term, while a caveat is a noted interest used for very short, urgent timing gaps. For a planned FY27 purchase with a clear exit, a registered second is usually the cleaner fit. Our second mortgage versus caveat loan comparison walks through both.
