A duplex can be a smarter entry point into the property market than a standalone house, particularly if you're buying in Craigieburn where dual occupancy properties are becoming more common in newer developments.
The main advantage is that you can live in one side and rent out the other, which reduces your mortgage repayments from day one. That rental income can make the difference between stretching your budget and buying comfortably. You also get access to the same first home buyer grants and concessions as you would with a traditional house, as long as the property meets eligibility criteria.
How a Duplex Reduces Your Actual Repayments
Living in one half of a duplex and renting the other side creates immediate cashflow that offsets your home loan repayments.
Consider a buyer who purchases a duplex in one of the newer estates near Hume Anglican Grammar. They live in one side and rent the other for around $400 per week. That's $1,733 per month going straight towards the mortgage. If their total monthly repayment sits around $2,800, they're only covering just over $1,000 themselves. Compare that to buying a standalone house where the full repayment falls on you, and the difference becomes clear. The rental income doesn't just help with repayments, it can also strengthen your borrowing capacity when you apply, because lenders factor in a portion of that expected rent when assessing how much you can borrow.

First Home Buyer Support That Applies to Duplexes
Duplexes qualify for Victorian first home buyer concessions and federal schemes, provided the property meets the relevant conditions.
Victoria offers a full stamp duty exemption on properties valued up to $600,000, and a reduced rate up to $750,000. If you're buying a newly built duplex, you may also be eligible for the $10,000 First Home Owner Grant, which applies to new homes valued under $750,000. At a federal level, the First Home Guarantee allows you to purchase with as little as a 5% deposit without paying Lenders Mortgage Insurance, and there are no income caps or property price limits anymore. These schemes stack, so a duplex buyer in Craigieburn purchasing a new build could access stamp duty relief, the grant, and the Guarantee all at once, significantly lowering upfront and ongoing costs.
What Lenders Look for When You Buy a Duplex
Lenders treat duplexes differently depending on whether it's on one title or two separate titles, and whether you're living in part of it or treating the whole thing as an investment.
If the duplex is on a single title and you're occupying one side, most lenders will assess it as an owner-occupied purchase. They'll factor in a percentage of the expected rental income from the other side when calculating your borrowing capacity, usually around 80% of the market rent to account for vacancy and costs. If it's on two separate titles, some lenders may treat the rented side as an investment loan, which can affect your interest rate and borrowing power. It's worth discussing your situation with a broker early, because the way the property is structured on title can change which loan products are available and how much you can borrow. Some lenders are far more comfortable with duplexes than others, particularly when rental income is part of the servicing picture.
Craigieburn's Duplex Market and What to Expect
Craigieburn has seen a growing number of duplex developments, particularly in estates around Aitken Hill and Mount Ridley, where land has been subdivided to accommodate dual occupancy builds.
These properties tend to appeal to first home buyers because they offer a way into the market without needing the full deposit or income required for a larger standalone home. The proximity to Craigieburn Station, local schools like Aitken Creek Primary, and the Highlands Shopping Centre makes the area attractive for renters, which supports your ability to lease out the second dwelling. Rental demand in the area has stayed consistent, driven by families and workers commuting into Melbourne's northern employment hubs. When you're assessing a duplex, pay attention to whether both sides have separate access, parking, and amenities, because tenants value privacy and lenders prefer properties that can function independently on each side.
Applying for a Home Loan on a Duplex Property
The home loan application process for a duplex is similar to a standard purchase, but you'll need to provide additional information about the rental side of the property.
Lenders will want to see a rental appraisal or evidence of current tenancy if the property is already leased. If it's a new build or vacant, they'll use a valuation that includes an estimated rental yield. You'll also need to show that you can service the loan based on your income plus the rental contribution. Some lenders require a larger deposit for duplex purchases, particularly if the property is on two titles or if you're not occupying either side. Getting pre-approval before you start looking gives you a clear budget and shows sellers you're in a position to move quickly, which can matter in competitive estates where duplex stock is limited.
Ongoing Costs and Responsibilities
Owning a duplex means you're responsible for maintaining both dwellings, even though you're only living in one.
You'll need to budget for repairs, insurance, property management if you use an agent, and potentially strata fees if the duplex is part of a broader development. Landlord insurance is separate from your home and contents cover, and it protects you if the tenant causes damage or stops paying rent. Council rates and water charges may be structured differently depending on whether the property is on one or two titles, so confirm how those bills are issued before you settle. If you're managing the tenancy yourself, you'll also handle lease agreements, routine inspections, and any maintenance requests. Many first-time landlords underestimate how much time that takes, so it's worth factoring in the cost of a property manager if you'd rather keep things hands-off.

Frequently Asked Questions
Can I use the First Home Guarantee to buy a duplex?
Yes, the First Home Guarantee applies to duplexes as long as you're purchasing the property to live in. You can buy with a 5% deposit and avoid paying Lenders Mortgage Insurance, even if you're renting out the other side.
Do I qualify for the Victorian First Home Owner Grant on a duplex?
You can qualify for the $10,000 grant if the duplex is a new build valued under $750,000 and you intend to occupy it as your principal place of residence. The grant applies even if you rent out the other dwelling.
How much rental income can I expect from a duplex in Craigieburn?
Rental income varies depending on the size and location of the duplex, but properties in newer estates near Craigieburn Station typically rent for between $380 and $450 per week. Lenders usually assess around 80% of that income when calculating your borrowing capacity.
What deposit do I need to buy a duplex as a first home buyer?
With the First Home Guarantee, you can purchase a duplex with a 5% deposit. Without the scheme, most lenders require at least 10% to 20%, depending on the property and whether it's on one or two titles.
Will I pay more interest if I buy a duplex instead of a house?
Not necessarily. If the duplex is on one title and you're living in it, you'll generally access the same owner-occupied interest rates as a standalone house. If it's on two titles and part is treated as investment, the rented side may attract a slightly higher rate.
