Quick answer
Directors often use their home to secure a business loan because residential property unlocks larger amounts, longer terms and more flexible credit assessment than unsecured lending. Every owner on the title must sign, and the home is at risk if the loan isn't repaid. The decision should rest on a realistic repayment plan, independent advice and an honest conversation with everyone who lives there.
Key points
- Residential property is the most widely accepted security in business lending.
- Every registered owner signs, including a spouse not involved in the business.
- The loan is a business loan, so household income matters less than the business plan.
- The risk to the home is real, so the repayment plan must be too.
- Positions available
- First mortgage, second mortgage or caveat
- Who signs
- Every registered owner, usually as mortgagor and guarantor
- Key protection
- A realistic exit or repayment plan and independent advice
- Credit check to enquire
- None
For many Australian business owners, the family home is the most valuable thing they own and the most obvious source of security. Using it to back a business loan can open doors that turnover alone never would. It’s also a decision that touches everyone who lives there. This page covers both sides, because a lender who only tells you the first half isn’t doing you a favour.
Why lenders value a home as security
From the credit desk, residential property is the most reliable security there is. Houses and units in established areas have deep pools of buyers, plenty of comparable sales for valuers to work from and well-understood legal processes. That reliability is why a home can support:
- amounts well beyond what an unsecured business loan would allow, up to $5,000,000 for strong properties;
- longer terms and lower relative cost than unsecured facilities;
- more flexibility with short trading history, credit marks or ATO debt;
- faster decisions, because the property carries much of the risk.
How it works in practice
A home can secure a business loan in three ways, depending on what’s already owing:
- First mortgage, if the home is owned outright or the existing home loan is refinanced. See first mortgage business loans.
- Second mortgage, sitting behind an existing home loan that stays in place. See second mortgage business loans.
- Caveat, for very short, urgent needs with a clear exit. See caveat loans.
In each case the borrower is usually the company, and the homeowners give the security, typically by signing the mortgage and a guarantee.
Who has to sign
Every person on the property’s title must sign the mortgage. If the home is owned jointly with a spouse or partner who isn’t a director, they’ll still need to sign, and most lenders ask them to sign a guarantee too. Lenders commonly require, or strongly recommend, that non-director owners get independent legal advice before signing, so they understand exactly what’s at stake. That isn’t a formality; it protects them and it protects the loan from being challenged later.

The questions to ask yourself first
Before using your home, work through these honestly, ideally with your accountant:
| Question | Why it matters |
|---|---|
| What exactly is the money for? | Investment in growth is very different from covering ongoing losses |
| How will the loan be repaid? | Business cash flow, a sale, a refinance or a contract payment |
| What if that takes twice as long? | Delays are common; the plan needs slack |
| What if the business fails? | Could the household still meet the home loan and this debt? |
| Does everyone on title agree? | Signing under pressure leads to regret and disputes |
If the answers are clear and realistic, using a home can be a sound, even conservative, way to fund a company. If they’re vague, it’s worth pausing.
Ways to limit the risk
You can reduce exposure in practical ways:
- Borrow what’s needed, not what’s available. Equity isn’t a target.
- Check whether the guarantee can be limited to a set amount.
- Keep the term realistic, with a buffer beyond your expected exit.
- Consider other security, such as an investment property or commercial premises, if available.
- Keep the home loan itself up to date, because arrears there affect everything.
If you’re worried about the company’s ability to pay its debts, ASIC’s insolvency information for directors is a sensible read before taking on more.
How Company Cash approaches home-secured loans
We lend against homes regularly, and we take it seriously. We’ll ask about the purpose and the exit early, explain the documents in plain language, and tell you if we think the plan is too tight. If an unsecured option or a smaller amount would do the job, we’ll say so. Small businesses can also take complaints about lenders to the Australian Financial Complaints Authority, whose small business information explains how it works.
Talking it through as a family
Lenders don’t often say this, but the conversation at the kitchen table matters as much as the one with the lender. Explain to everyone on the title what the money is for, how long it’s needed and what the plan is if things go slower than expected. Agree in advance how you’ll handle a bad month. Owners who make the decision together tend to stick to the plan, and that’s a large part of why these loans work out.
Find out what your home could support
If you’re weighing up using your home, talk to us before you decide. Our 60-second enquiry involves no credit check, your details aren’t passed to a list of other lenders, and a real person will walk through the numbers and the risks with you. Please include an honest estimate of the home’s value and what’s owing, plus who’s on the title, so we can tell you straight what’s realistic. Start the conversation.
Frequently asked questions
Can I use my home if my spouse isn't a director?
Yes, but every registered owner must sign the mortgage, and most lenders also ask non-director owners to sign a guarantee. Many lenders require or strongly recommend independent legal advice for those owners.
Will the lender assess my household income?
For a loan used for business purposes, the focus is mostly on the business and the exit. Some lenders still look at household finances for longer loans, particularly to check the home loan will keep being paid.
What happens if the business can't repay?
The lender will usually work with you first, but if the default isn't fixed it can take steps to enforce its security, which can ultimately mean selling the property. That's why the repayment plan matters so much.
Can I limit how much of my home is at risk?
Some guarantees can be limited to a set amount, and the mortgage secures only the debts it describes. Read both documents carefully and ask the lender to explain the scope before signing.
Is there an alternative that doesn't use my home?
Unsecured cash flow lending, invoice finance or security over other property, such as an investment property or commercial premises, may work depending on the amount and the company's trading.
