First Home Buyers, buying a property with family or friends can make homeownership more affordable, but it comes with unique risks and responsibilities. From joint tenants vs. tenants in common to shared loans and exit strategies, understanding your options is crucial. This guide explains how co-ownership works, the pros and cons, and the loan structures available in Australia, so you can make informed decisions and know what to expect when purchasing your home.

Why Co-Ownership is Becoming More Common
With property prices rising across Australia, many buyers are looking to pool resources with siblings, parents, or friends. Co-ownership can make it easier to:
- Get into the property market sooner.
- Afford a better location or larger property.
- Share investment opportunities.
While the idea is appealing, the purchase and loan structure is critical to avoid disputes or financial setbacks.
Buying your home can feel overwhelming, but the process doesn’t need to be a mystery. Our step-by-step guide explains the typical timeline for buying a home.
Ownership Structures:
Joint Tenants vs Tenants-in-Common
Joint Tenants
- All parties own the property equally (e.g., 50/50).
- If one owner passes away, their share automatically goes to the surviving owner(s).
- This is common for couples, but less common for friends or siblings.
Tenants-in-Common
- Ownership is divided into specific shares (e.g., 70/30).
- Each party can sell or pass on their share independently.
- Provides flexibility when parties contribute different amounts.
Tip: Tenants-in-common is often the better fit when buying with family or friends, as it recognises unequal contributions.
Loan Structure Options for Co-Ownership
1. Joint Loan
- All borrowers are equally responsible for the entire loan.
- Simpler for lenders, but if one person defaults, all parties are liable.
2. Separate Loans (Split Loans with Shared Security)
- Each co-owner takes out their own loan for their share of the property.
- Useful when one party wants to pay down debt faster or borrow differently.
- Not all lenders offer this option, but it can reduce risk.
3. Guarantor Structure (Family Contribution)
- Parents may go as guarantors for a child’s share.
- Allows one party to borrow with additional security while protecting the other’s share.
Pros & Cons of Buying Together
Pros:
- Easier entry into the market.
- Ability to afford better property or location.
- Shared responsibility for expenses.
Cons:
- The risk arises if one party can’t meet repayments.
- Potential disagreements over selling, renting, or renovating.
- Harder to exit compared to owning solo.
Why It Matters for Homeowners & Investors
For first-home buyers, co-ownership may be the only way to enter the market. For investors, pooling resources can create bigger opportunities.
Example:
- Two siblings purchase an investment property as tenants in common, with a 60/40 split based on their contributions. Each takes their own loan and claims tax deductions separately. This avoids issues if one sibling wants to sell their share later.
