Property joint ventures vs borrowing more: how to choose wisely

Using a property joint venture instead of borrowing more personally makes sense when extra debt would push your risk, cashflow or borrowing capacity too far, but the deal still stacks up if you share it.

In practice, JVs suit situations where (1) your personal serviceability is near its limit, (2) you’d be over‑exposed to one asset if you did it alone, or (3) a partner brings capital, security or skills you simply don’t have. The decision needs to factor in tax, asset protection and lending rules—not just “can I get the loan?” this week.

Weighing up more personal debt versus a structured property joint venture.

1. What a property joint venture really is (and isn’t)

A property joint venture is a deal where two or more parties agree to share capital, risks, profits and decision‑making for a specific property project.

It is not automatically safer or cheaper than borrowing more personally. It’s just a different blend of:

• Who puts in equity
• Who takes the loans and guarantees
• How profits and control are split

Common JV structures in Australia

• Simple co‑ownership JV
  Each party owns a share of the property (e.g. 50/50 tenants in common), usually with a separate JV agreement.

• Unit trust or company JV
  The property is held in a unit trust or company; each party owns units/shares. Often used for small developments and business premises.

• Land + funding + expertise split
  One party contributes land, another contributes capital, another does the build or project management.

Whichever structure you use, keep one core principle from other structuring work: clean separation and clarity beats complexity (see how this plays out with multiple securities).

2. JV vs borrowing more personally: key differences

Here’s how a JV compares with simply taking on more personal debt for an investment or business property.

Worked example: stretching vs sharing risk

Assume:

• Investment project requires $1.2m total (purchase + costs + works)
• Lender will fund up to 80% LVR on $1m purchase = $800k loan
• You need $400k equity

Option A – Borrow personally
You refinance your home and existing investment, pulling $400k equity into a new split (purpose: investment). That lifts your total personal debt from $1.2m to $1.6m.

Stress‑testing repayments at 3% above current rates (APRA buffer), your total repayments now sit close to 35–40% of after‑tax income. In today’s environment where Roy Morgan shows over 30% of borrowers ‘At Risk’ of mortgage stress, that’s uncomfortable.

Option B – JV with a capital partner
You and a partner agree:

• Partner contributes $250k cash
• You contribute $150k from equity
• Loan remains $800k in a JV entity

Your personal extra borrowing drops from $400k to $150k. You may give up, say, 40% of the profit, but your family balance sheet is far less exposed if rates rise or the project runs over‑time.
