Top tips to choose the right property ownership structure

Ownership structure changes what lenders will offer

The name on the property title determines which loan products you can access, how much you can borrow, and what happens if circumstances change. Lenders assess sole ownership, joint tenancy, and tenants in common differently, and that difference shows up in the interest rate you pay and the features you can use.

Consider a couple buying in Mount Eliza where one partner earns significantly more than the other and already owns an investment property. If they apply jointly as owner-occupiers, the lender sees the existing investment loan and adjusts serviceability accordingly. If the higher earner applies alone, their debt-to-income ratio might push them into a higher rate tier or reduce the amount they can borrow. If they structure as tenants in common with unequal shares, some lenders will require separate applications with different loan amounts, which changes the way offset accounts and redraw facilities work across the loan.

In our experience, buyers focus on the deposit and the rate, then discover months later that the ownership structure they chose limits their ability to refinance or add features they assumed would be available.

Joint tenancy versus tenants in common

Joint tenancy means equal ownership and automatic transfer to the surviving owner if one person passes away. Tenants in common allows unequal shares and lets each owner nominate who inherits their portion. Both structures work for owner-occupied property, but lenders treat them differently when you apply for a home loan.

Under joint tenancy, all owners must be on the loan, and the lender assesses combined income and combined liabilities. Under tenants in common, some lenders will allow separate applications where each owner borrows against their share, though this is less common for residential property and usually requires a larger deposit. Most lenders still prefer all owners to be co-borrowers regardless of the ownership split, which means the structure affects estate planning more than loan structure in practice.

The choice matters most when one owner has existing debt, a lower income, or different tax circumstances. For example, if one partner is self-employed and the other is a PAYE employee, some lenders apply different serviceability buffers to each income type. Structuring as tenants in common with unequal shares doesn't change that assessment, but it does allow one owner to refinance their portion later without requiring consent from the other, assuming the lender permits it.

Sole ownership and borrowing capacity

Buying alone means the lender assesses only your income and liabilities, which can work in your favour if your financial position is strong and you're not relying on a second income to meet serviceability. Sole ownership also means full control over refinancing, selling, or using equity later, without needing consent from a co-owner.

The challenge appears when your income alone doesn't support the loan amount you need. Lenders apply a serviceability buffer, typically adding 3% to the current variable rate and calculating whether you can afford repayments at that higher rate. If you're borrowing close to your limit, even a small rate rise or a change in your employment situation can affect your ability to refinance or increase the loan later.

Sole ownership also removes the option to add a co-borrower later without refinancing the entire loan. If you meet a partner and want to add them to the title, you'll need to discharge the existing loan and reapply, which triggers new application fees, valuation costs, and potentially a different rate depending on market conditions at the time.

Company or trust structures for investment purposes

If the property is for investment rather than owner-occupied use, some buyers consider purchasing through a company or trust. This changes the tax treatment, the asset protection available, and the loan products you can access. Most lenders treat loans to companies and trusts as commercial lending, which means higher rates, lower loan-to-value ratios, and shorter loan terms compared to a standard residential investment loan.

Company ownership means the company is liable for the loan, but directors usually provide personal guarantees, which removes most of the asset protection benefit while adding compliance costs. Trust ownership can offer more flexibility for distributing income and capital gains, but the trustee must apply for the loan, and most lenders require individual trustees rather than corporate trustees for residential property.

For owner-occupied property in Mount Eliza, purchasing through a company or trust is uncommon and usually limits your ability to access owner-occupied rates, which are typically lower than investment rates. If you're considering this structure, speak with an accountant before you apply, because changing the structure later requires selling the property to the new entity, which triggers stamp duty and capital gains tax.

Adding or removing owners after settlement

Changing the names on the title after you've settled requires refinancing in most cases. Lenders won't allow you to add a co-owner to an existing loan without reassessing serviceability and rewriting the loan contract. Removing an owner usually requires the remaining owner to refinance and demonstrate they can service the loan independently.

This process can take several weeks and involves the same costs as a standard refinance, including valuation fees, application fees, and legal costs. If you're planning to add a partner or family member to the title within the first few years, consider including them from the start, even if their income contribution is minimal. Some lenders allow co-borrowers with low or no income if the primary borrower meets serviceability alone, which gives you the flexibility to structure ownership the way you want without needing to refinance later.

How ownership structure affects future borrowing

The way you structure ownership now determines how much equity you can access later. If you own jointly, both owners must agree to any refinance or equity release. If one owner has a change in income or credit history, that affects the entire application, even if the other owner's financial position has improved.

In a scenario where one owner wants to buy a second property using equity from the Mount Eliza property, the lender will assess the application as if both owners are purchasing the new property, even if only one will be on the new title. This is because both owners are liable for the existing loan, and the lender needs to confirm that releasing equity won't affect your ability to service both loans. Structuring as tenants in common doesn't change this in most cases, because lenders still require all owners to consent to any change in the loan.

If you're planning to build a portfolio or purchase additional property in the future, the way you structure your first purchase sets the pattern for how lenders will assess your borrowing capacity across all properties.

Ownership structure isn't something you can easily change later, and the decision affects more than just tax and estate planning.
