Quick answer · Q.A07

Yes. Your home can secure a business loan through a first mortgage, a second mortgage behind your existing home loan, or a caveat. Property-secured business loans range from $20,000 to $5,000,000. The loan must be for business purposes, everyone on the title must be involved, and the amount depends on your home's value and existing mortgage. The trade-off is that your home is at risk if the loan isn't repaid.

Key points

  • A home can secure a business loan via a first mortgage, second mortgage or caveat.
  • You can often keep your existing home loan in place and borrow behind it.
  • Everyone on title must agree and sign; lenders often require independent legal advice for co-owners who aren't borrowers.
  • The loan must be used for business purposes, even though the security is a home.

How does a home secure a business loan?

The lender takes a registered interest on your home’s title, so it can look to the property if the business loan isn’t repaid. There are three common ways to do it:

MethodWhat happens to your home loanTypically used for
New first mortgageExisting home loan is repaid and replacedLarger amounts, longer terms, simplifying debt
Second mortgageExisting home loan stays; new lender ranks secondAccessing equity without touching the home loan
CaveatCaveat lodged on title; home loan staysShort-term needs with a clear repayment event

Whichever method is used, the loan is still a business loan. The money must go to business purposes — tax, stock, equipment, wages, buying a business, refinancing business debt and so on.

How much could my home support?

It depends on two numbers: what the lender believes the home is worth, and what’s already owed on it. Lenders cap the total debt against a property at a maximum loan-to-value ratio, and the usable equity is the room left under that cap. We walk through an illustrative calculation in how much equity you can borrow against.

Home-secured business loans sit within the property-secured range of $20,000 to $5,000,000. For most owner-occupied homes, the practical limit is set by the equity, not the range.

Who needs to sign?

Everyone with a registered interest in the home. That usually means:

  • The borrower — you, or your company.
  • Every co-owner on title, even if they’re not in the business. They’ll typically sign a guarantee and the mortgage.
  • Directors of a borrowing company, usually as guarantors.

Many lenders ask co-owners who don’t directly benefit from the loan to get independent legal advice. It isn’t box-ticking; it protects everyone, including you, from a later dispute about whether they understood the risk.

What should I weigh up before using my home?

Using your home can unlock a larger amount, a longer term and more flexibility on credit history. It can also put the place your family lives on the line. Before you decide, work through these honestly:

  1. Is the purpose likely to pay for itself or prevent a bigger cost? Clearing an ATO debt before it escalates, for example, is different from funding an untested idea.
  2. What’s the repayment plan? Trading income, a sale, a refinance, a receivable — be specific.
  3. What happens in a bad year? Could the business, or your household, carry the repayments if revenue dipped?
  4. Is everyone at home on board? Have that conversation early.
  5. Is there a smaller alternative? An unsecured facility for part of the need might reduce how much the home carries.

A real person can help you think through these without any pressure. Send a short enquiry and you’ll get a call — no credit check at the enquiry stage.

Can I use my home if my credit isn’t perfect?

Often, yes. Property security gives lenders more room to look past old defaults or recent difficulties, because they’re relying on the asset as well as the business. It’s still assessed case by case, and the lender will want to understand what happened and why it’s behind you. Our page on bad credit business loans covers the details.

What’s the process, step by step?

  1. Enquiry — what you need, what it’s for, the home’s approximate value and current mortgage.
  2. Conversation — a specialist checks the purpose, the numbers and who’s on title.
  3. Application — ID, business information and, depending on the lender, bank statements or financials.
  4. Valuation — the lender orders its own assessment of the home.
  5. Documents — loan contract, mortgage or caveat, guarantees, legal advice certificates if needed.
  6. Settlement — the mortgage or caveat is registered and funds are paid out. See what happens at settlement.

How do I talk about it at home?

For many owners, the hardest part of using the home isn’t the paperwork — it’s the conversation with a partner or family member who shares the property. A few things make it easier:

  • Lead with the purpose and the numbers, not the loan. What problem does it solve, what does it cost, and how is it repaid?
  • Be clear about the worst case. What would happen if the business had a bad year, and what’s the fallback?
  • Agree on limits. An amount, a term and a date by which the loan should be cleared or reviewed.
  • Invite questions to a professional. A co-owner getting independent legal advice isn’t a sign of distrust; it’s how everyone ends up comfortable with the decision.

Having that conversation before an application also saves time later, because the co-owner’s signature and advice certificate are often the final pieces needed before settlement.

What if the money is partly for personal use?

It can’t be. A business loan secured on your home must be used predominantly for business purposes, and you’ll typically sign a declaration saying so. Personal spending — a renovation, a holiday, a car for the family — belongs in consumer lending instead. See using a business loan for personal expenses for where that line sits.

See whether your home can back your business

If you’re weighing up your home as security, start with a conversation, not an application. Enquiring is free of any credit check, your details aren’t passed around a crowd of lenders, and a real person looks at your home’s equity and your business need together. Give accurate figures for the home’s value and what’s owed, and who’s on title, so the answer you get is the one you can rely on.

Frequently asked questions

Will I need to refinance my home loan?

Not necessarily. A second mortgage or caveat can sit behind your existing lender so your home loan stays as it is. Refinancing into a single new first mortgage is another option if it suits better.

My partner co-owns the house but isn't in the business. Can I still use it?

Only with their agreement and signature. Every registered owner must be part of the security. Lenders commonly require a co-owner who isn't a borrower to get independent legal advice so they understand what they're agreeing to.

Can a company borrow against a director's home?

Yes. This is very common. The company borrows, and the director gives a guarantee and a mortgage over the home. The loan is still assessed as a business loan.

Is a home-secured business loan regulated like a home loan?

A loan predominantly for business purposes is generally treated as business lending rather than consumer credit, even when a home is the security. You'll typically be asked to sign a business purpose declaration. Read it carefully and only sign if it's true.

What happens to the loan if I sell my house?

The loan secured on the house is normally repaid from the sale proceeds at settlement, unless the lender agrees to move the security to another property. Planning a sale can actually be a sensible exit for a short-term property-secured loan.
