Personal guarantees when your company owns the home: what’s really at risk

Owning your home through a company or trust doesn’t magically ring‑fence your risk from the bank. In Australia, most lenders will still make you sign a personal or director guarantee, which allows them to chase you personally if the loan goes bad. If you’re a small business owner, investor or professional using entities, you need to understand exactly what you’re promising and how to contain the damage before you sign.

In this guide we’ll unpack how personal guarantees work when your entity owns the home, what lenders can really do, where limited‑recourse structures actually help, and what you can practically do this week to tidy your risk.

Owning your home through an entity rarely removes the need for personal guarantees.

1. What is a personal or director guarantee, really?

A personal guarantee is a legal promise by an individual to be responsible for a loan or other debt if the main borrower (your company or trust) does not pay. A director guarantee is simply a personal guarantee given in your capacity as a director. In home loans, guarantees commonly:

1. Make you personally liable for any shortfall if the property sale doesn’t clear the debt.
2. Allow the lender to pursue your personal assets (savings, investments, wages, other property) to recover that shortfall.
3. Sit alongside the mortgage over the property, not instead of it.

1.1 Why lenders insist on guarantees for entity‑owned homes

From a bank’s perspective, a company or trust that owns your main residence is usually just a “wrapper” around your personal wealth. They see through the structure and focus on:

• Who benefits from living in the home.
• Who controls the entity and its money.
• Who can actually pay the loan.

That’s why, in practice:

• Most mainstream lenders require full personal guarantees from directors and/or adult beneficiaries when an entity owns the family home.
• The guarantee is usually unlimited – it covers all money the entity owes to that lender now and in future under that facility.

If you’ve read our guide on how lenders view your business at home‑loan time, you’ll recognise the pattern: they look past the ABN and assess the real human risk profile behind it. See /insights/how-lenders-really-view-your-small-business-home-loan.

1.2 Guarantee vs mortgage: different tools, same outcome

It helps to separate two ideas:

• Mortgage – security over the property. Lets the bank sell it if the loan defaults.
• Guarantee – security over you. Lets the bank chase you if the mortgage sale doesn’t clear the debt.

In a bad downside scenario (forced sale in a weak market, or fire sale after relationship breakdown), the mortgage gets the bank the sale proceeds. The guarantee is what lets them come after the rest if there’s a shortfall.

2. Common structures: where guarantees show up

If your entity owns, or might own, your home, you’re likely in one of these camps.

2.1 Company on title, director living there

Your Pty Ltd is on the title as owner; you and your family live in the property. This might have been set up for perceived asset protection or tax flexibility.

In this case, lenders will almost always require:

• The company as borrower.
• Each director to sign a director’s guarantee (and often their spouse/partner as a co‑borrower or co‑guarantor).

If the company cannot pay (for example, business revenue collapses and the company is wound up), the bank can still:

• Enforce the mortgage over the property, and
• Use your personal guarantee to go after your non‑company assets for any remaining debt.

2.2 Discretionary (family) trust with corporate trustee

The trust is on title, with a company as trustee. You’re a director of the trustee and a primary beneficiary of the trust.

Typical lender response:

• The trustee company is the borrower.
• All directors of the trustee give personal guarantees.
• Often, at least one adult beneficiary (usually you) is also asked to guarantee.

The trust structure adds estate and tax planning flexibility, but does not stop lenders from requiring guarantees.

2.3 SMSF limited‑recourse borrowing arrangement (LRBA)

For SMSF property, the law requires a limited‑recourse structure. That means if the SMSF defaults, the lender can only take action against the property in the bare trust, not the rest of the SMSF assets.

However:

• Many lenders still require personal guarantees from the members.
• The guarantee is usually limited to the LRBA debt, but it still creates a personal exposure if the sale doesn’t cover the loan.

SMSF lending is one of the few places where limited recourse is built into the law, but personal guarantees can still drag risk back into your personal world.

2.4 Business loan secured by your home

Even if your home is in your personal name, many small‑business facilities do this:

• Business borrows (company or trust).
• You sign a director guarantee.
• Your home (even if owned by a trust or spouse) is offered as security.

This is where earlier decisions can collide. If you later try to refinance your home loan, that business guarantee can spook new lenders.

3. What can actually happen if things go wrong?

Personal guarantees are not “theoretical”. They are enforceable contracts. If a home loan in your entity’s name goes seriously off the rails, lenders usually move in stages.

3.1 The normal enforcement sequence

While every case is different, a typical escalation looks like:

1. Missed repayments and arrears – reminder notices, then formal default notices after a set period.
2. Attempts to agree a solution – temporary hardship variation, repayment plan, or refinance.
3. Enforcing the mortgage – taking possession and selling the property if the loan remains in default.
4. Chasing the shortfall – if the sale price doesn’t clear the debt and costs, the lender can:
   • Demand payment from you under the guarantee.
   • Commence court action to obtain judgment.
   • Enforce against your other personal assets or income.

In practice, most banks prefer a negotiated outcome rather than scorched earth, particularly if you’re engaging early and honestly. But they have the legal tools to pursue you.

3.2 Example: shortfall after forced sale

Assume:

• Your family trust owns the home, worth $1.4m on a good day.
• The LR is $1.1m, interest only.
• You personally guaranteed the loan.

Business revenue collapses; you fall behind on repayments. After enforcement and a quick sale in a soft market, the home only achieves $1.15m, and sale/legal costs are $50,000.

• Net sale proceeds: $1.10m
• Debt including arrears, interest and costs: $1.18m
• Shortfall: $80,000

Under the guarantee, the bank can demand this $80,000 from you personally and, if unpaid, pursue:

• Your personal cash savings.
• Other investments.
• Your share of any other property.

This is why relying purely on “the entity owns the property” as asset protection can be dangerous.

3.3 The cross‑collateralisation trap

Sometimes the guarantee risk is amplified by cross‑collateralisation – where multiple properties secure one or more loans.

If:

• Your company owns your home.
• The same lender also holds your investment property as security.
• You give a personal guarantee for all company borrowings.

Then a default on the home loan can put your investment property at risk too. Untangling this later can be complex; it’s one reason we emphasise clean splits and careful security choices in every structure decision.
