Top tips to finance a mixed-use development purchase

Buying a mixed-use development in Melbourne means you're looking at a property that generates income from multiple sources under one roof.

Most lenders treat these properties differently to standard residential or purely commercial assets, and the loan structure you choose will determine how much deposit you need, what interest rate you pay, and how flexible your repayment options are. The challenge is that one lender might assess the entire building as commercial property, while another splits the valuation between commercial and residential components. Your finance structure needs to match both the physical layout of the building and the way you plan to use it.

Why lenders treat mixed-use properties as commercial assets

A mixed-use development is classified as a commercial property loan because the building serves multiple purposes, even if part of it includes residential tenancies. The moment you combine retail or office space with residential under the same title, most lenders apply commercial lending criteria. That means you'll typically need a larger deposit, between 20% and 40% depending on the lender and the income profile of the property. The loan amount is based on a commercial property valuation that considers rental yield, tenant mix, and lease terms rather than comparable sales alone.

Consider a buyer looking at a three-storey building in Fitzroy with ground-floor retail, first-floor office space, and two residential apartments on the top level. The valuer assesses each component separately, then applies a commercial LVR to the total. One lender might offer 70% of the valuation if the retail and office tenants have long-term leases in place, while another caps it at 60% because the residential component doesn't generate commercial-grade returns. The difference in those two offers could mean an additional $200,000 in deposit required, which changes the entire feasibility of the purchase.

How loan structure changes with tenant mix and lease terms

The way your building is tenanted directly affects the loan structure a lender will offer. A mixed-use property with established commercial tenants on multi-year leases will generally qualify for better terms than a building with short-term or vacant tenancies. Lenders assess the stability of your rental income, and they give more weight to commercial tenants than residential ones when calculating serviceability.

If your development includes retail space leased to a national tenant on a five-year agreement and residential apartments on six-month tenancies, the lender will base most of their serviceability assessment on the commercial lease. They might allow you to include 80% of the commercial rent in your income calculation but only 50% of the residential rent, depending on the vacancy rate in that suburb. This affects how much you can borrow and whether you need additional income sources to service the loan.

Variable or fixed interest rates for mixed-use developments

Most commercial property loans offer both variable and fixed interest rate options, but the choice depends on your cashflow and how long you plan to hold the asset. A variable interest rate gives you the flexibility to make extra repayments or pay down the loan early without penalties, which can be helpful if your tenants pay quarterly rent in advance or if you plan to sell within a few years. A fixed interest rate locks in your repayment amount for a set period, usually between one and five years, which works if you want certainty around your holding costs.

In our experience, buyers who intend to renovate or redevelop part of the building within the first few years tend to prefer variable rates because they need the flexibility to refinance or restructure the loan as the property changes. On the other hand, buyers who want stable repayments and have no immediate plans to alter the building often choose a fixed rate, particularly if they're managing the loan alongside other business commitments.

When progressive drawdown applies to a mixed-use purchase

Progressive drawdown is typically associated with construction loans, but it can also apply to mixed-use purchases if the property needs significant work before it's fully tenanted or habitable. If you're buying a building that requires a fitout for the commercial tenancies or renovations to bring the residential component up to rental standard, some lenders will structure the loan so funds are released in stages as the work is completed.

This approach reduces the lender's risk and can lower your initial interest costs because you're only paying interest on the amount drawn down at each stage. However, not all lenders offer this structure for purchases, and you'll need a clear scope of works and timeline to qualify. If your building in Collingwood has vacant retail space on the ground floor and needs a full commercial fitout before a tenant moves in, a lender might release 70% of the purchase price at settlement and the remaining 30% once the fitout is complete and a lease is signed.

How collateral and loan security work across mixed-use assets

When you're financing a mixed-use development, the building itself serves as collateral for the loan. The lender registers a mortgage over the title, and if the property is strata-titled with separate lots for commercial and residential, they'll take security over the entire holding. In some cases, lenders will also require additional security if the LVR is high or if the income from the property doesn't fully cover the loan repayments.

If you're buying a mixed-use building in Prahran with a loan amount that sits at 75% LVR, the lender might ask for a second property as additional security or require a director's guarantee if the purchase is made through a company structure. The type of security required depends on your financial position, the strength of the lease agreements, and the lender's appetite for mixed-use assets in that location.

Choosing between secured and unsecured commercial loan options

A secured commercial loan uses the property as collateral, which typically results in a lower interest rate and access to higher borrowing amounts. An unsecured commercial loan doesn't require property security but comes with a higher interest rate and stricter serviceability criteria. For most mixed-use development purchases, a secured loan is the standard option because the loan amount is substantial and the property itself provides the security the lender needs.

Unsecured options are rare in this space and are generally only considered if you're a high-net-worth buyer with strong cashflow and the lender is willing to rely on your business financials rather than property security. For a typical Melbourne mixed-use purchase, expect to use the building as collateral and structure the loan accordingly.

Flexible repayment options and how they apply to rental income

Most commercial property finance offers flexible repayment options, including interest-only periods and principal-and-interest structures. An interest-only loan reduces your monthly repayments during the initial term, which can help with cashflow if you're still stabilising tenancies or completing renovations. The downside is that you're not reducing the loan amount, so you'll need a plan to either refinance, sell, or switch to principal-and-interest repayments when the interest-only period ends.

If your mixed-use building generates consistent rental income that exceeds your loan repayments, principal-and-interest repayments let you pay down the debt over time and build equity in the property. In our experience, buyers who plan to hold the asset long-term tend to prefer principal-and-interest structures, while those focused on short-term gains or active property management lean toward interest-only.

When commercial refinance becomes part of your strategy

Commercial refinance is worth considering once your building is fully tenanted and generating stable income. If you purchased the property with a higher interest rate or a conservative LVR due to vacant tenancies, refinancing after the leases are in place can unlock better terms and potentially free up equity for future purchases.

Refinancing also makes sense if you've completed a fitout or renovation that increased the property's value. A fresh commercial property valuation will reflect the improved income and building condition, which may allow you to borrow more or reduce your interest rate. Timing is important, and you'll want to weigh the costs of refinancing against the potential savings or access to additional capital.

Working with a finance and mortgage broker for commercial property

A commercial finance and mortgage broker gives you access to commercial loan options from banks and lenders across Australia, including those that specialise in mixed-use developments. Not all lenders are comfortable with these properties, and some have specific criteria around tenant mix, location, or building condition. A broker can structure the loan to suit your goals, whether that's minimising your deposit, securing flexible loan terms, or setting up a revolving line of credit for future property expenses.

The advantage is that a broker works through the different lender policies and presents options that align with the way you plan to use the building, rather than offering a one-size-fits-all product. For a mixed-use purchase in Melbourne, that often means the difference between a loan that works from day one and one that limits your options as your plans evolve.
