Quick answer

A property owned by a company or a trust can secure a second mortgage behind its existing loan. The company grants the mortgage through its directors; a trust grants it through its trustee, provided the trust deed allows further borrowing and security. Directors usually guarantee. The step most people miss is checking what the first lender already holds, such as all-moneys clauses or cross-guarantees, before going second.

Key points

  • Companies grant the mortgage through directors; trusts through the trustee
  • The trust deed must permit the trustee to borrow and give further security
  • Check the first lender's all-moneys clauses and existing guarantees first
  • The borrower and the property owner can be different related entities
  • Companies, trusts and sole traders can all borrow, including start-ups
Borrowers
Companies, trusts and sole traders, including start-ups — no minimum trading period or turnover
Amounts
$20k – $5m
LVR
Up to 80% of value on residential security and up to 70% on commercial (lower on large acreage)
Valuation
No sworn valuation — we assess value ourselves

Plenty of business property isn’t owned by a person. The factory is in the operating company, the warehouse is in a family trust, the rental is in a separate property company set up years ago on the accountant’s advice. When that property already has a bank loan on it and the business needs more, a second mortgage can sit behind the bank, but the structure adds a layer of questions an individual owner never faces.

Our page on company or trust owned property explains the general rules for using an entity’s property as security. This page is specifically about going second: borrowing behind an existing lender when the title is held by a company or trust.

How does a second mortgage work when a company owns the property?

The company is the registered proprietor, so the company grants the mortgage. It signs through its directors in the way its constitution allows, and your solicitor confirms the execution is correct. The directors almost always give personal guarantees as well.

Before any of that, two quick checks:

  • Who is on the title? Land Use Victoria explains that each folio in the register shows the proprietor and encumbrances such as mortgages, caveats and leases. The exact company name on title must match the company signing.
  • Is the company in good standing? ASIC’s registers let anyone search company details. A current extract shows directors, the registered office and status.

How does it work when a trust owns the property?

A trust can’t sign anything itself. The trustee holds the property and signs on the trust’s behalf. Three things decide whether a second mortgage is possible:

  1. The deed’s powers. It must allow the trustee to borrow and to mortgage trust property, ideally including further or second-ranking security and guarantees for related parties if another entity is the borrower.
  2. The right trustee. If the trustee has changed over the years, the title and the deed’s variations must line up with who is trustee today.
  3. A corporate or individual trustee. A corporate trustee signs through its directors, who usually guarantee. Individual trustees sign personally and in their capacity as trustee.
Item Company owner Trust owner

Common delay Name mismatch between title and ASIC Missing deed variations or a trustee change never updated on title

What does the first lender already hold?

This is the question most owners skip, and it’s the one that most often changes the numbers. Business banks tend to take broad security, so before going second, check:

  • All-moneys clauses. Many bank mortgages secure every debt the customer owes the bank, including overdrafts, equipment loans and guarantees. The true first-ranking debt can be larger than the property loan statement suggests.
  • Cross-guarantees. The bank may hold guarantees between related companies and trusts, so one entity’s property already supports another’s borrowing.
  • Cross-collateralisation. The bank may hold mortgages over several properties for one combined facility. Our guide to freeing a property from cross-collateralised loans explains how that can be unwound.
  • Consent clauses. Many first mortgages require the bank’s permission before further security is granted. See our guide to first mortgagee consent.

Ask your bank for a statement of every facility secured by the property. It’s the single most useful document for a company or trust second mortgage. If you’d like to talk it through first, start with a 60-second enquiry.

Can the property owner and the borrower be different entities?

Yes, and it’s common. A family trust owns the premises; the operating company needs the money. In that case:

  • the operating company is the borrower;
  • the trust (through its trustee) gives the second mortgage over its property and usually a guarantee;
  • the directors of both typically guarantee personally.

This is a form of third-party security. Moneysmart’s guidance on going guarantor is blunt about the stakes: a guarantor may have to repay the whole loan if the borrower can’t, and should get advice before signing. Where family members are directors or trustees but aren’t involved in the business, independent legal advice matters even more.

What do company and trust borrowers use a second mortgage for?

The uses mirror any business owner’s, with a few that come up more often in group structures:

  • funding the operating company from equity held in a property trust;
  • paying an ATO debt in one entity using property held in another, including where directors face a director penalty notice;
  • buying out a departing director or unitholder;
  • a deposit or settlement shortfall on a purchase by a related entity.

All funds must go to business purposes.

Illustrative example: a Melbourne food manufacturing group runs its business through an operating company, while a unit trust owns the factory, worth about $2.4m, with $1m owing to a bank. The operating company needs $450k for a new production line. The bank’s facility statement shows an extra $150k overdraft secured by the same mortgage. Illustrative: at a 70% commercial band, total lending could reach $1.68m; after the true first-ranking debt of $1.15m, there’s $530k of room. The trust’s corporate trustee grants the second mortgage, the operating company borrows, and both companies’ directors guarantee.

What slows company and trust second mortgages down?

The same few issues come up again and again, and each is cheap to fix early:

  • A missing deed variation. Trusts set up decades ago often have a variation or change of trustee sitting in an accountant’s file. Find it before you enquire.
  • A director who can’t sign quickly. Overseas or unavailable directors and guarantors need signing and identity arrangements planned on day one.
  • A bank facility nobody mentioned. An overdraft or equipment facility under an all-moneys mortgage changes the room available.
  • A deregistered or renamed entity in the chain. A quick ASIC search catches it.
  • Unclear borrower. Decide early which entity is borrowing and which is giving security, so documents are drawn correctly the first time.

Which papers should you gather first?

  • a current ASIC extract for every company involved, including any corporate trustee;
  • the trust deed and every variation, plus the latest trustee resolution if your solicitor asks for one;
  • photo ID for every director, trustee and guarantor;
  • the bank’s statement of all facilities secured by the property;
  • what the funds are for and how the loan will be repaid.

Our documents for a private mortgage guide lists the standard items for every borrower.

Frequently asked questions

Can a family trust give a second mortgage over its property?

Yes, if the trust deed gives the trustee power to borrow and to mortgage trust property, including by way of further security. Your solicitor or accountant can confirm the relevant clauses. Having the deed and every variation ready avoids delay.

The property is in our company but the loan is for a different business we own. Is that allowed?

Often, yes. The property-owning entity gives the second mortgage as security, and the borrowing entity takes the loan. The owner entity usually also gives a guarantee. Everyone involved should understand that the property is backing another entity's debt.

Do the directors have to guarantee personally?

Usually, yes. Personal guarantees from directors are standard when a company or a corporate trustee borrows or gives security. Each guarantor should get independent legal advice before signing.

What is an all-moneys clause and why does it matter?

It's a term in many bank mortgages that makes the property secure every debt the customer owes that bank, not just the original loan. If your first mortgage has one, the true first-ranking debt may be larger than the loan statement shows, which reduces the room for a second mortgage.

Can a trust with a corporate trustee borrow by second mortgage?

Yes. The corporate trustee signs as trustee of the trust, through its directors, and the directors usually guarantee. You'll need the company extract for the trustee as well as the trust deed.

Does a company need a minimum trading history?

No. There's no minimum trading period or turnover. A newly formed company or trust can borrow if the property has equity and there's a clear exit.
