A second mortgage over your home or investment property can fund part of a business purchase, usually the deposit or goodwill. Here is how it works, what the lender reads and how you get out of it once the business is yours.
Quick Answer
You can use a second mortgage over your home or investment property to fund part of a business purchase, usually the deposit or goodwill, but the lender will look at the business you are buying, the contract and how you plan to repay or refinance it. The house secures it, the business repays it, which is why second mortgage loans for a purchase are usually paired with a clear plan for funding goodwill and getting out.
Also called: second mortgage business purchase, using home equity to buy a business. Both describe the same thing: borrowing against property you already own to fund part of buying a business someone else has built.
Can you use a second mortgage to buy a business?
You can use a second mortgage to buy a business, and it is one of the more common ways self-employed buyers fund the part of a purchase that a business lender will not. A second mortgage sits behind your existing first mortgage, so your home loan stays where it is and you borrow against the equity above it.
The house secures it, the business repays it. That line explains most of how the lender thinks. The property gives the lender something to fall back on, but because the money is for a business purpose, the lender still wants to see how the business you are buying will carry the repayments and how you will get out of the loan later. Most second mortgages used this way are short term business purpose loans from non-bank and private mortgage lenders, because major banks rarely lend behind another lender's first mortgage.
If you are still deciding whether a second mortgage suits you at all, the second mortgage guide covers how one works and what it costs, and can I get a second mortgage covers eligibility. More property-backed options sit in the Property Lending Hub. This post stays on the purchase.
Second mortgage, bank top-up, cash out refinance or acquisition loan: which route fits?
The route that fits depends on how much equity you hold, how quickly the seller needs the money and whether your income evidence will satisfy a bank today. There are four common ways to turn property or the business itself into purchase funds, and they suit different buyers.
| Route | What secures it | What the lender reads | Speed, in principle | How you exit |
|---|---|---|---|---|
| Second mortgage | A registered mortgage over your home or investment property, behind the first mortgage | Equity above the first mortgage, the purchase contract, the business and your exit | Often the quicker option, varies by lender | Refinance into an acquisition loan or a larger first mortgage once you have trading history, or a sale |
| Bank top-up | Your existing first mortgage, increased | Your full income and servicing, plus the purpose of the funds | Depends on the bank's credit queue, often slower for self-employed files | Ordinary repayment over the home loan term |
| Cash out refinance | A new, larger first mortgage that replaces the old one | Full servicing on the new loan and evidence of what the cash is for | Typically the slowest, because the whole loan moves | Ordinary repayment over the new loan term |
| Acquisition loan | The business assets and goodwill, usually with a director's guarantee, sometimes property as well | The target's financials, the contract and your industry experience | Varies with how clean the seller's figures are | Repaid from business cash flow over its term |
In deals I've seen, the second mortgage is rarely the whole funding. It usually sits beside an acquisition loan or vendor terms and covers what those will not: the deposit, part of the goodwill, or the working capital you need on day one.
The loan to buy a business guide covers the acquisition loan side in full, including deposit size and documents. If a bank top-up is on the table, the cash out refinance limits guide explains what banks ask before they release equity, and second mortgage vs a bank cash out refinance weighs the two directly.
What do lenders check on the business you are buying?
Lenders check the business you are buying even when the loan is secured by your house, because the business is what repays it. The lender still reads the business, alongside the property and you.
- The contract of sale. The price, what is included, when the deposit is due, the settlement date and any conditions such as finance approval, lease assignment or franchise approval.
- The seller's trading figures. Recent financials, BAS and bank statements, read as a check that the business can carry the repayments rather than as a full home loan style assessment.
- Your experience. Whether you have worked in the industry or run a similar business. A buyer stepping into a trade they know reads very differently from a first time owner.
- The purpose declaration. Most second mortgages used to buy a business are written as business purpose loans, and you will usually sign a declaration that the funds are for a business purpose. That declaration generally means the consumer credit protections in the National Credit Code do not apply to the loan, so read it with your solicitor before you sign. The second mortgage lenders guide explains what that declaration means for you.
- The exit. How the second mortgage will be repaid at the end of its term. How private lenders assess the exit plan covers this before approval.
Reads cleanly
- A signed contract with clear conditions
- Seller figures that support the asking price
- Industry experience you can show
- A written exit with a target date
Stalls the file
- Goodwill priced on promises
- A lease assignment not yet agreed
- Figures the seller will not release
- No plan for the end of the term
Across the purchases we see, the one that stalls is rarely the one with thin equity. It is the one where the seller's figures do not match the story, or where the lease or franchise approval is still open when the lender is ready to settle. What lenders check on a second mortgage business loan covers the wider file.
Can a second mortgage fund goodwill as well as the deposit?
A second mortgage can fund goodwill as well as the deposit, because the lender secures the loan against your property rather than against the goodwill itself. That is exactly why buyers use it: goodwill is the hard part to fund. Goodwill is the value of the business above its physical assets, its customers, name and earnings, and many business lenders will lend against only part of it, or none of it, without other security.
The real decision is not whether a second mortgage can fund goodwill but whether it should. If most of the price is goodwill and the business underperforms, the property is what is left to repay the loan. Before you lean on the house for goodwill, read who funds goodwill when you buy a business, and compare what changes when premises come with the purchase in buying a business with property or without.
How does a second mortgage fund a business purchase, step by step?
A second mortgage funds a business purchase in five broad steps, from the offer to the day the keys change hands. The walkthrough follows the salon purchase from the top of this post: a small business on a premises lease, a buyer with equity in her home, and a seller who wants a deposit and a firm settlement date. It is illustrative only, with no rates, approval odds or real client details.
- Offer and contract. The buyer agrees a price, makes the contract subject to finance and to the landlord consenting to assign the lease, and her solicitor reviews it before she signs.
- Funding split. Her broker sets out which part an acquisition lender will fund against the business and which part needs other security. The gap, the deposit plus part of the goodwill, becomes the second mortgage amount.
- Property and business assessment. The second mortgage lender orders a valuation of the home, confirms the first mortgage balance and reads the contract, the seller's figures and her experience. She signs the business purpose declaration.
- Consent and conditions. The lender's solicitor deals with the first lender where consent or a deed of priority is needed, while the lease assignment and any franchise approval are tracked against the settlement date.
- Settlement. The second mortgage is registered on the title as a registered mortgage, the funds settle the purchase alongside the acquisition loan, and she takes over the business with a written plan for repaying the second mortgage.
The steps rarely move at the same speed. The second mortgage is often ready before the lease is, which is the subject of the next section. What sets the clock on a short term second mortgage covers the lender side of the timing.
How do franchise approval, lease assignment and settlement timing affect the second mortgage?
Franchise approval, lease assignment and settlement timing decide when the second mortgage can actually be drawn, because most lenders will not release funds for a purchase that cannot complete. The lease and the franchise set the clock, not the lender.
Why does the lease assignment matter to the lender?
The lease assignment matters because a business on a premises lease is only worth its price if the new owner can stay in the premises. The landlord usually has to consent to the lease being assigned to you, and may ask for your financials, a bank guarantee or a personal guarantee first. Until that consent is in place, most lenders treat the purchase as incomplete.
What changes when the business is a franchise?
A franchise adds a second approval, because the franchisor generally has to accept you as the new franchisee, often after an interview, training or a look at your finances. Lenders typically want that approval in writing before settlement, and some franchisors have their own view on how the purchase is funded, including whether the family home is used as security.
What if the settlement date arrives before everything is ready?
If the settlement date arrives before the approvals do, the usual fix is an agreed extension to the contract rather than drawing the loan early. Drawing a second mortgage before the purchase can complete means paying interest on money you cannot use yet, and the lender's approval may itself carry a date by which it has to settle. Ask your solicitor to line the finance, lease and franchise conditions up to the same date, so one is not left hanging.
How do you get out of the second mortgage after the purchase?
You get out of the second mortgage by repaying it from a refinance, a sale or other funds before its term ends, and that plan should exist before you sign. The exit is an acquisition loan once you have history, typically: after you have run the business for a period and can show its figures under your ownership, a business lender can look at refinancing the purchase debt into a longer loan against the business, or a home lender can look at a larger first mortgage. Your exit strategy is part of the application, not an afterthought.
The other common exits are seller terms and a sale. If the seller agrees to be paid part of the price over time, vendor finance can shrink what the second mortgage needs to cover in the first place. If a property or the business is sold, the payout figure is settled from the proceeds and the mortgage is discharged.
When the refinance comes, business loans is where that conversation starts, and second mortgage exit rules for business purpose loans covers what lenders accept as an exit.
What are the risks of securing a business purchase against your home?
The main risk of securing a business purchase against your home is that if the business underperforms and the loan cannot be repaid or refinanced, the lender can look to the property. The business is meant to repay the loan, but the house is what secures it if the business cannot.
- Personal liability. A second mortgage over your home is usually given in your personal name, often alongside a director's guarantee on the acquisition loan, so buying through a company does not keep the home out of reach.
- Underperformance. Turnover can dip after a sale while customers adjust to a new owner. Build in a buffer rather than assuming the seller's best year repeats.
- Refinance risk. If the figures under your ownership come in weaker than planned, refinancing out of the second mortgage can be harder or take longer, while the term keeps running.
- Co-owners. If someone else owns the property with you, they will usually have to sign the mortgage too, and should get their own advice first.
The government's guide to buying an existing business on business.gov.au sets out the checks to make before you buy, and is worth working through before the house goes up as security. If the property you would borrow against is commercial rather than residential, the commercial second mortgage guide covers how lenders treat that security, including where a second lender stands on default. How the purchase is structured, and what securing it against your home means for you personally, are questions for your solicitor and your accountant before you sign.
A second mortgage can fund the part of a business purchase that business lenders will not, usually the deposit or goodwill, by borrowing against equity in property you already own. The lender still reads the business, the contract and your experience; the lease and the franchise set the clock on settlement; and the way out, typically a refinance into an acquisition loan once you have trading history, should be written down before you sign.
Key takeaway: line the finance, lease and franchise conditions up to one date, and know your exit before the house goes up as security.Frequently Asked Questions
A second mortgage to buy a business works by borrowing against the equity in property you already own, behind your existing first mortgage, and using the funds for part of the purchase price. Most buyers use it for the deposit or goodwill alongside an acquisition loan or vendor finance, then repay it by refinancing once the business has trading history under them.
You can borrow money to buy an existing business through an acquisition loan secured against the business, a loan secured against property you own, terms from the seller, or a mix of these. Lenders look at the business's figures, the contract and your experience in the industry. The loan to buy a business guide covers each option.
The best way to finance buying an existing business depends on the price, how much of it is goodwill, the equity you hold in property and how quickly the seller needs to settle. Many purchases combine an acquisition loan with seller terms or a second mortgage for the gap, rather than relying on one source. A broker can model the split before you sign the contract.
You can use your home equity to buy a business, either through a second mortgage behind your current home loan or by increasing or refinancing that home loan. The equity available depends on your property's valuation and what you already owe. Because the loan is for a business purpose, lenders still read the business you are buying.
Lenders usually do need the business's financials even when the loan is secured by your house, because the business is expected to repay it and the lender has to judge the exit. How deep the review goes varies by lender: a private lender may focus on the contract, the seller's figures and your plan rather than a full serviceability test.
