A mixed-use development combines commercial and residential tenancies under one title or strata plan, and that split changes how lenders assess both serviceability and risk.
How Lenders Classify Mixed-Use Property
Most lenders treat mixed-use developments as commercial property once the commercial component exceeds a certain threshold. That threshold varies between lenders, but the most common trigger is 25 per cent of the total lettable area. Above that point, the property falls under commercial lending criteria, which means different interest rates, shorter loan terms, and a valuation that focuses on income rather than comparable sales.
Consider a buyer looking at a three-storey building in Fortitude Valley with two street-level retail tenancies and six apartments above. The retail component represents 30 per cent of the total lettable area. Even though the majority of the property is residential, the loan will be assessed as a commercial property loan because the commercial portion exceeds the threshold. The buyer will need to provide lease agreements for the retail tenancies, demonstrate that the rental income covers the proposed loan repayments, and accept a loan-to-value ratio capped at 70 per cent in most cases.
The commercial property valuation will rely on a capitalisation rate applied to the net rental income from both the residential and commercial components. If the retail tenancies are vacant or on short-term leases, the valuation will drop, and the loan amount may be reduced accordingly.
What Loan Structure Applies to Mixed-Use Purchases
A secured commercial loan is the standard structure for mixed-use property finance. The property itself serves as collateral, and the lender will register a first mortgage over the title. Loan terms typically range from three to five years for investment purchases, with principal and interest repayments calculated on a 20 to 25-year amortisation schedule. At the end of the initial term, the loan either refinances or converts to a new rate.
Some lenders offer a split structure where the residential component is financed under a residential investment loan and the commercial component is financed separately. This approach works when the property is subdivided into separate strata titles, with clear division between the commercial and residential portions. The residential loan may attract a variable interest rate with more flexible repayment options, while the commercial portion is subject to commercial interest rates and stricter serviceability requirements.

In scenarios where the property is held under a single title, the split structure is not available. The entire loan falls under commercial lending criteria, and the buyer will need to demonstrate that the combined rental income from both components can service the debt. Lenders typically apply a serviceability buffer of 2 to 3 per cent above the actual rate and may discount residential rental income by 20 per cent to account for vacancy and tenant turnover.
Deposit and Serviceability Requirements for Mixed-Use Finance
Most lenders cap the loan amount at 70 per cent of the property valuation for mixed-use developments, which means the buyer needs a 30 per cent deposit plus settlement costs. Some lenders will extend to 75 per cent if the buyer has a strong servicing position and the property is in a high-demand location, but anything beyond that typically requires a guarantor or additional security.
Serviceability is assessed on the net rental income after deducting outgoings such as body corporate fees, council rates, insurance, and maintenance. Lenders will request a rental schedule for all tenancies, copies of existing lease agreements, and evidence of recent rental payments. If any tenancy is vacant or due to expire within six months of settlement, the lender may exclude that income from the serviceability calculation or apply a discount.
As an example, a buyer purchasing a mixed-use property in West End with a ground-floor cafe and two residential units above might show gross rental income of $120,000 per year. After deducting $25,000 in outgoings, the net income is $95,000. The lender will assess serviceability at a test rate of around 8 per cent, which means the loan repayment cannot exceed the net income after applying the buffer. If the buyer is seeking a loan of $1.2 million, the annual repayment at 8 per cent over 25 years would be approximately $111,000, which exceeds the net income. The loan would not be approved without additional income from other sources or a larger deposit to reduce the loan amount.
Strata Title Commercial Components and Cross-Collateralisation
When a mixed-use development is subdivided into strata title commercial and residential lots, each lot can be financed separately. The commercial lot may be purchased by one buyer and the residential lots by another, or a single buyer may acquire multiple lots under separate loan agreements. This approach offers more flexibility but introduces complications around body corporate control, shared services, and cross-collateralisation.
If the same buyer holds multiple lots and uses them as security for different loans, the lender may require cross-collateralisation, which means all properties are tied to all loans. If one loan defaults, the lender can claim against any or all of the properties. This reduces flexibility if the buyer wants to sell one lot or refinance part of the portfolio later.
Some buyers use a line of credit or revolving facility to manage cash flow across multiple tenancies within a strata title commercial development. This loan structure allows the buyer to draw down funds as needed for maintenance, tenant improvements, or vacancy periods, then repay the balance when rental income is received. The interest rate on a revolving line of credit is typically higher than a standard term loan, but the redraw function and flexible repayment options can justify the cost in properties with variable income.
Why Location and Tenant Mix Affect Approval
Lenders assess mixed-use developments based on the strength of the tenant mix and the location's demand for both commercial and residential space. A property in New Farm with long-term commercial tenants and high residential occupancy will attract more favourable loan terms than a similar property in a suburb with high vacancy rates or declining commercial demand.
In Brisbane's inner suburbs, mixed-use properties near transport hubs, universities, or employment centres tend to perform well because they serve both business and residential markets. A property within walking distance of the Brisbane CBD or near the South Bank precinct will be viewed more favourably than a similar asset in an outer suburb with limited public transport and fewer amenities.
If the commercial tenancy is a medical practice, professional office, or established retail business with a lease term of five years or more, the lender will view the income as stable and reliable. If the commercial component is a startup cafe or a tenant on a month-to-month agreement, the lender may discount or exclude that income entirely. The buyer may need to provide personal income or other investment property income to meet serviceability requirements.
When Mezzanine Financing or Pre-Settlement Finance Is Required
Some buyers use mezzanine financing to bridge the gap between the standard 70 per cent commercial LVR and the total purchase price. Mezzanine debt sits behind the primary loan and is secured by a second mortgage or a charge over the business or other assets. The interest rate on mezzanine financing is higher than the primary loan, often in the range of 10 to 15 per cent, and the term is usually 12 to 24 months.
This structure is more common in commercial development finance or land acquisition scenarios, but it can apply to mixed-use purchases where the buyer has limited cash but strong income or other assets. The mezzanine lender will require detailed financial projections, evidence of rental income, and a clear exit strategy, such as refinancing once the property is fully tenanted or selling another asset to repay the debt.
Pre-settlement finance is another option when the buyer needs to secure the property quickly but has not yet sold an existing asset or finalised another transaction. This short-term loan, typically 3 to 12 months, allows the buyer to settle on the mixed-use property and then refinance into a standard commercial loan once the other transaction completes. The interest rate is higher than a standard loan, but the structure can prevent a missed opportunity in a competitive market.

Frequently Asked Questions
How do lenders decide if a mixed-use property is commercial or residential?
Most lenders classify a property as commercial if the commercial component exceeds 25 per cent of the total lettable area. Above that threshold, the property is assessed under commercial lending criteria, which affects interest rates, loan terms, and serviceability requirements.
What deposit is required for a mixed-use property purchase?
Most lenders cap the loan at 70 per cent of the property valuation, which means a 30 per cent deposit plus settlement costs. Some lenders may extend to 75 per cent for strong applicants in high-demand locations, but anything beyond that typically requires additional security.
Can I finance the residential and commercial parts of a mixed-use property separately?
If the property is subdivided into separate strata titles, you may be able to finance the residential and commercial components under different loan structures. If the property is held under a single title, the entire loan will fall under commercial lending criteria.
How do lenders assess rental income for mixed-use properties?
Lenders calculate net rental income after deducting outgoings such as body corporate fees, council rates, and maintenance. They may discount residential rental income by 20 per cent and exclude vacant or short-term commercial tenancies from the serviceability calculation.
What is mezzanine financing and when is it used for mixed-use purchases?
Mezzanine financing is a second-tier loan secured behind the primary commercial loan, used to bridge the gap between the standard 70 per cent loan-to-value ratio and the purchase price. It carries a higher interest rate and is typically used when the buyer has limited cash but strong income or other assets.
