Only one business partner owns property: how to make a secured loan fair to both of you

Two people built the business together. They share the work, the stress and the profits. Then the business needs capital, the lender wants property, and only one of them owns any. Suddenly a fifty-fifty partnership has one partner’s family home on the line and the other partner’s name only on the paperwork.

It’s one of the quieter tensions in small business, and it’s worth talking about before the loan, not after. A second mortgage in this situation can still be the sensible choice. It just needs a fair deal between the partners first.

Is it unfair for one partner to put their house up?

Not automatically. It becomes unfair when the risk lands on one person while the benefit is split down the middle, and nobody has written down what happens if things go wrong.

Here’s what’s actually lopsided. If the business can’t repay, the lender’s most practical way to recover is to sell the property it holds as security. The owning partner may lose equity, or in the worst case the home itself. The other partner shares in everything the loan pays for, and may walk away with their own assets largely intact.

That said, the partner without property is rarely risk-free:

• Companies. Lenders commonly ask every director to give a personal guarantee, whether or not they own property. That guarantee is a real personal debt if the company defaults, even if there’s no house behind it today.
• General partnerships. business.gov.au says that in a general partnership “each partner has unlimited liability” for the partnership’s debts. A partner without property still owes their share and more.
• Future assets. A guarantee can follow someone for years. A partner who buys a home after signing may find it within reach of a claim later.

So the real question isn’t “is this fair?” in the abstract. It’s “have we agreed how the risk is shared?”

What are the ways to balance it?

Most partners use one or a combination of the following. None of them is complicated, but each needs to be written down and, ideally, drawn up by a lawyer.

Tool	What it does	Works best when
Contribution agreement	The partner without property agrees to reimburse their share of any loss if the security is called on	Partners have similar incomes and the relationship is solid
Security or guarantee fee	The business pays the owner a regular fee for providing the property	The loan will run for a while and the business has steady cash flow
Adjusted profit share	The owner takes a larger share of profits until the loan is repaid	Profits are reliable and both want simplicity
Repayment priority	The loan is paid down before either partner draws profits above an agreed wage	The partners want the property released as soon as possible
Capped amount	The loan secured on the owner’s property is limited to a set figure	The owner has a clear line on how much risk they’ll take

A few notes on each.

The contribution agreement is the one most partners skip and the one that matters most. It doesn’t change what the lender can do. It changes what happens between you afterwards. If the lender recovers $200k from the owner’s property, a fifty-fifty contribution agreement means the other partner owes the owner $100k. It turns a moral obligation into an enforceable one.

A security fee compensates the owner for the risk and for tying up their equity, which they might otherwise use for their own plans. It has tax consequences on both sides, so let your accountant set the amount and the paperwork.

Profit share and repayment priority are often the most natural fit for small partnerships. Agreeing that the loan is repaid before anyone draws profits above wages keeps both of you focused on getting the property off the hook.

A cap protects the owner’s household. Agree the figure before the loan is sized, not after a lender has suggested a bigger number.

What if the owner’s spouse is on the title?

This is where things often get overlooked. If the property is owned jointly with a spouse or partner who isn’t in the business, they must sign the mortgage too. They’re carrying risk for a business they don’t own and may not be involved in at all.

They deserve the full picture: what the money is for, the numbers, the exit, and the contribution agreement that protects their household. They’re entitled to independent legal advice and time to think. Our guide to talking it through with a co-owner covers that conversation in detail. A contribution agreement often makes it much easier, because the spouse can see their home isn’t simply absorbing the other partner’s share of the risk.

Who should borrow: the business or the owner?

Usually the business borrows, and the owner provides their property as security, typically through a guarantee backed by a mortgage. That keeps the debt where the benefit is, and it’s the cleanest structure for most partners. Our page on using someone else’s property as security explains how that kind of arrangement works and why limiting the guarantee is worth asking about.

Sometimes partners consider the owner borrowing personally and lending the money to the business. That changes who owes the lender, who carries the interest cost and how it’s treated for tax. The ATO’s long-standing determination TD 93/13 says interest deductibility is “determined by the use of the borrowed money”, not by what secures it. But who borrows, and how the money reaches the business, still shapes the result. That’s a question for your accountant before anything is signed, and our questions to ask your accountant are a good starting list.

If you’ve worked through the fairness side and want a specialist to look at whether the numbers stack up, you can send a short enquiry. There’s no credit check when you first enquire.

How do you plan the exit when partners might part ways?

Partnerships change. People retire, fall out, move interstate or get an offer they can’t refuse. The mortgage doesn’t care: it stays on the owner’s property until the loan is repaid or refinanced, even if the owner sells their share and resigns as a director.

Build the release into your agreements from day one:

1. Name the primary exit. Repayment from cash flow, a refinance into the business’s own facility once it has a stronger trading record, or a sale. The exit plan page walks through each.
2. Set a release date to aim for. For example, “the business will refinance and release the property within two years”. Put a checkpoint halfway.
3. Tie it to any buyout. If either partner leaves, the buyout price and terms should include paying out or refinancing the loan so the property comes off. See funding a partner buyout for how that tends to work.
4. Agree a fallback. If the refinance doesn’t happen on time, what then? Selling a business asset, extra contributions from the partner without property, or reducing the debt from profits are all common answers.

An illustrative example

Two partners run a joinery business. Sam owns a home worth $1,100,000 with a $450,000 home loan, a combined LVR of about 41%. Priya rents and has no property, but she brings most of the sales work and an equal share of the business. They win a large fit-out contract and need $180,000 of working capital to carry materials and wages until the progress payments arrive.

A $180,000 second mortgage takes Sam’s combined LVR to about 57%. If the home were valued 10% lower, it would be about 64%. The equity decision helper suggests a reasonable cushion either way.

Before going ahead they agree four things in writing, with a lawyer:

• a fifty-fifty contribution agreement, so Priya shares any loss on Sam’s home;
• no profit distributions above agreed wages until the loan is repaid;
• a target to refinance into a business facility within 18 months, with a checkpoint at month nine;
• any buyout of either partner must include releasing Sam’s home.

Sam’s wife, who is on the title, reads the agreement and gets her own legal advice before signing. Illustrative only; no rates or repayments shown.

When is it better not to use the property?

Sometimes the honest answer is “not this”. It’s worth pausing if:

• The partner without property won’t sign a contribution agreement. That tells you how the risk would really be shared.
• The owner’s spouse is uneasy. A reluctant co-owner is a warning, not an obstacle to work around. See protecting the family home.
• The relationship is already strained. A loan secured on one partner’s house magnifies every disagreement.
• An unsecured option would do the job. A trading business with steady turnover may be able to use an unsecured loan or line of credit and keep the property out of it entirely.
• What the business really needs is another owner. If the partners can’t fund growth between them, taking on an investor may be the fairer answer.

Two partners, one sensible decision

When one partner’s property carries the loan, the money is the easy part. The agreement between you is what keeps the partnership and the friendship intact. If you’ve had that conversation, or you’d like to have it with real numbers in front of you, we’re happy to look at whether a second mortgage suits your business or whether something lighter would work.

The enquiry takes about a minute and there’s no credit check when you first enquire. Your details go to one specialist, not out to a pile of lenders, so there’s no flood of calls. A real person reads your situation, calls you, and will tell you plainly if a second mortgage isn’t the right move. Please fill the form in accurately, including whose property it is, who’s on the title, what’s owed, the amount, the purpose and how you plan to repay. It means the first call is a useful one for both partners.
