Second Mortgage in Perth: What Landgate Registers and What It Doesn't
How a second mortgage works in Perth and WA: what Landgate registers, whether your first lender must agree, stamp duty and what happens on default.

Second Mortgage Perth · Landgate · Western Australia
A second mortgage on a Western Australian title is a Landgate document. The rules that decide whether you may sign it sit in your first loan. Here is what Landgate registers, what your contract decides, and how default works in WA.
Quick Answer
Landgate registers a second mortgage behind the first in the order documents are lodged; whether you may grant one is set by your first loan's terms, not by Landgate. Lenders then weigh the property, your equity and your exit. Our second mortgage loans page covers how the deal is assessed.
Also called: second mortgage WA, second mortgage Western Australia, Landgate second mortgage. Same product; the place name changes the search, not the loan.
How does a second mortgage work on Perth or Western Australian property?
On a Landgate title, a second mortgage is a registered mortgage that ranks behind your existing first mortgage, so the second lender is repaid after the first if the property is ever sold. You keep the first loan in place and borrow against the equity above it.
Two sets of rules meet in every deal. The lender assesses you the same way it would anywhere in Australia: the property, the equity, the purpose and how the loan ends. The title, though, is governed by Western Australian law, the Transfer of Land Act 1893, and Landgate keeps the register. That is why we describe it as a Landgate document, a loan-contract decision: Landgate decides whether the document can sit on the title, and your existing loan decides whether you were allowed to sign it.
Business owners in Perth typically use a second mortgage for working capital, an ATO debt, a deposit on another property, stock or equipment, or to bridge a gap until a sale or refinance. This post covers business-purpose lending only; a loan for personal or household purposes falls under the National Credit Code and is a different conversation. The second mortgage guide covers cost, timelines and risks nationally, and if you own more than one property, our post on using two properties as security shows when a second title changes the structure.
In practice, the Western Australian part of the deal is mostly about paperwork and sequence. The harder questions, equity and exit, are the same in Perth as in Sydney.
What does Landgate register for a second mortgage?
Landgate registers the mortgage document itself: the national mortgage form naming the parties, the land and the terms the mortgage carries. Its MTG-01 Mortgages guide makes two points that matter for a second mortgage. First, since 1 December 2018 all eligible stand-alone mortgages must be lodged electronically. Second, a mortgage whose terms conflict with the Act will not be registered. Put simply, terms that clash with the Act are not registered, however the lender drafted them.
Once registered, the second mortgage appears on the certificate of title behind the first, in the order the documents were lodged. Anyone who searches the title, including the next lender you approach, sees both mortgages and any caveats. If you want to change the ranking between lenders, that is done by agreement, usually a deed of priority, which our post on bank consent and the deed of priority explains.
| Item | Where it sits | Who checks it |
|---|---|---|
| The mortgage document | National mortgage form, recorded on the Landgate title | Landgate, at lodgement |
| The mortgage terms | The registered mortgage and any terms it incorporates | Landgate refuses terms that conflict with the Transfer of Land Act |
| How it is lodged | Electronically for eligible stand-alone mortgages, since 1 December 2018 | The lender's settlement agent or lawyer |
| Ranking behind the first mortgage | The title, in order of lodgement, unless the lenders agree otherwise | Landgate records it; a deed of priority changes it between lenders |
| Whether you may grant a second mortgage | Your first mortgage and first loan contract | Your solicitor, and your first lender |
| Your capacity to repay and your exit | The second lender's credit file, not the title | The second lender, typically with a broker |

What does Landgate not check?
Landgate does not check whether your first lender agreed, whether you can afford the repayments, or what the money is for. Those questions belong to the contracts and to the second lender. A mortgage can be registered cleanly and still breach the first loan, which is why the next section matters more than the paperwork.
Does your first lender have to agree to a second mortgage in Western Australia?
Whether your first lender has to agree to a second mortgage in Western Australia is decided by your first mortgage and loan contract, not by Landgate: its MTG-01 guide says the Registrar is generally not concerned with a mortgage's covenants beyond keeping them consistent with the Act. Many first mortgages and business loan agreements include a clause that restricts further mortgages or charges without the lender's written consent. If yours does, granting a second mortgage without that first mortgagee consent can be a default under the first loan even if Landgate registers the document.
In New South Wales and Queensland the registry itself does not ask for the first lender's consent, and our Sydney and New South Wales post sets out how that works there.
On the title
- The mortgage document, in the national form
- Its place behind the first mortgage
- Terms that comply with the Transfer of Land Act
- Any caveats already lodged
In your loan contract
- Whether further mortgages need consent
- What counts as a default on the first loan
- Cross-default triggers between loans
- Whether the first lender will sign a deed of priority
In practice, the first lender is asked early. Most second lenders want to know whether consent is needed and whether the first lender will sign a deed of priority before they issue an approval, because a refusal changes the structure. If consent will not come, the usual alternatives are refinancing the first loan, or a caveat-secured loan; our comparison of a second mortgage and a caveat loan explains the trade-off, and the Perth caveat loans post covers how a caveat sits behind a first mortgage at Landgate.
Before you approach a lender, it helps to check eligibility with your first loan statement and contract in hand. Whether a clause in your contract bites is a question for your solicitor, not for Landgate or a broker.
Is there stamp duty on a second mortgage in Western Australia?
Stamp duty is not listed for a mortgage in Western Australia: Landgate's LOD-03 guide on fees and transfer duty sets out the documents that must be stamped before registration, and a mortgage is not among them. For a second mortgage, that means no stamp to put on the mortgage before Landgate will register it.
That does not make the loan free to set up. The costs that typically apply are:
- Landgate's registration fee for the mortgage document, set by Landgate and revised from time to time.
- Lender fees, usually an establishment fee and sometimes a line or legal fee, which vary by lender.
- Legal costs for the lender's solicitor and, in most deals, your own.
- A valuation and title search, ordered by the lender and often paid by the borrower.
How those costs combine with the interest rate is covered in our post on second mortgage rates in Australia. Land tax and other Western Australian charges on the property are a separate matter, set out in the Perth caveat loans post linked above, and how they apply to your holdings is a question for your accountant.
What happens to a second mortgage if a lender enforces in Western Australia?
If a lender enforces in Western Australia, it must first serve a notice under section 106 of the Transfer of Land Act 1893 giving the borrower one month to remedy the default, and only then may it sell under section 108, according to Landgate's TFR-08 guide. That is one month to fix the default under section 106, from the notice, before a sale can proceed.
Landgate's FOR-01 guide adds that foreclosure, a separate remedy where the lender takes the property itself, needs the default to have continued for six months under section 121. In most deals sale, not foreclosure, is the route lenders take.
On a sale, the proceeds pay the first mortgagee first, then the second, then you. That order is why second lenders watch the first loan closely: a missed payment on the first can be an event of default on the second, and our post on how a first mortgage default triggers the loan behind it walks through that chain. How a sale works between first and second lenders, including marshalling, is covered in the commercial second mortgage guide.
If you receive a section 106 notice, speak to your solicitor straight away. The month runs from the notice, not from when you open it.
How do lenders treat Perth, regional and mining town property?
Lenders typically take metropolitan Perth houses most readily, assess regional property more cautiously, and treat single-industry and mining towns as the hardest security to place. Location changes a Western Australian deal more often than property type does: regional loan limits typically sit lower and vary by lender, and some lenders exclude whole postcodes.
The loan-to-value ratio on a second mortgage counts both loans, so the room left behind the first mortgage shrinks quickly on a property the lender values conservatively. The things a second lender usually checks on Western Australian security are:
- Location: metropolitan, regional centre, or a town that depends on one mine or one employer.
- Property type: a house on its own title is easier than rural land, a unit in a small complex or a specialised building.
- Valuation: what the lender's valuer will support, not the price you expect.
- Existing debt: the first mortgage balance and its conduct.
- The exit strategy: a sale, refinance or business event that repays the loan, and how long it realistically takes in that market.
Our regional property finance guide explains postcode limits and single-industry towns in more depth, and the second mortgage exit rules post covers how lenders read the exit. If a second mortgage is not the right fit, private lending structures or other options in the Property Lending Hub may be.
A second mortgage in Perth is a Landgate document, a loan-contract decision. Landgate registers the national mortgage form behind the first, electronically for eligible stand-alone mortgages, and refuses terms that clash with the Transfer of Land Act. It does not ask whether your first lender agreed; your first mortgage and loan contract decide that. There is no stamp to put on the mortgage, enforcement starts with a section 106 notice and one month to remedy, and location shapes how much a lender will lend behind the first.
Key takeaway: read your first loan's clause on further mortgages before you apply, and plan the exit for a Western Australian market, not a national average.Frequently Asked Questions
You can get a second mortgage in Perth when there is enough equity behind your first mortgage, a business purpose for the funds and a clear way to repay. Landgate registers the mortgage behind the first, but whether your first loan allows it is a contract question. Lenders weigh the property, your existing debt and your exit, which our second mortgage loans page sets out.
Stamp duty on a mortgage in Western Australia is not on Landgate's list: its LOD-03 guide sets out the documents that must be stamped before registration, and a mortgage is not among them. You still pay Landgate's registration fee and the lender, legal and valuation costs, which vary by lender and by deal. Our second mortgage rates post explains how those costs are typically built.
You register a second mortgage with Landgate by lodging the national mortgage form, and since 1 December 2018 eligible stand-alone mortgages have been lodged electronically. In practice the lender's settlement agent or lawyer handles lodgement, not the borrower. Landgate checks the document, and terms that conflict with the Transfer of Land Act are not registered, as our glossary entry on a registered mortgage explains.
Some lenders do accept mining town property for a second mortgage in Western Australia, typically with lower loan-to-value limits, and some exclude single-industry towns altogether. Policy varies by lender and can tighten when the local market turns. Our regional property finance guide explains how location limits work.
A section 106 notice in Western Australia is the default notice a mortgagee serves under the Transfer of Land Act 1893, giving the mortgagor one month to remedy the default, according to Landgate's TFR-08 guide. If the default is not fixed in that time, the mortgagee may move to sell under section 108. What a notice means for your property is a question for your solicitor, and our commercial second mortgage guide covers how a sale works between first and second lenders.
