Everything you need to know about duplexes in QLD…
What is a duplex?
In Queensland, a duplex is made up of two adjoining houses, connected by a shared wall. They are sometimes known as “dual key properties” in New South Wales or “maisonettes” in South Australia.
Duplexes are highly coveted by savvy investors, first home buyers, and retirees. It’s easy to see why. These exceptional properties offer a trifecta of benefits that appeal to every property owner’s desires: unparalleled versatility, broad market appeal, and the possibility of generating extra income.
Affinity can assist you with buying a duplex, selling a duplex, or leasing a duplex.
Configuration of a duplex property
While they share a connecting wall, each side of a duplex has its own ammenities and seperate entrances. Duplexes are configured in patterns such as:
6/4/4 – 6 Bedrooms, 4 Bathrooms, 4 Car Garage.
The example below shows a unique design for a corner lot.

5/3/2 – 5 Bedrooms, 3 Bathrooms, 2 Car Garage.

Selling single title duplex property
A single title duplex is when both sides of the building are on the same title. They can only be bought and sold together. However, each side can still be rented out seperately.
Selling dual title duplex property
Each side of the duplex has a separate title, and can be sold and bought individually. A dual title duplex has to have strata title to sell the sides individually, but this also provides greater flexibility.
Leasing a duplex
Managing duplexes requires an experienced set of hands. Depending on their configuration, arrangements may be different for the payment of utilities such as water and electricity. Property insurance and landlord Insurance may also be shared or split between lot owners. It’s important to select good quality tenants who are compatible to minimise the potential for any tenant disputes and also to maintain longer tendencies. Thereby reducing costs for landlords.

Single Title vs Dual Title for your duplex rental
Renting out property can be complex, especially with duplexes. In Queensland, duplexes have either single or dual titles. Dual title duplexes incur higher costs due to separate fees for rates, water, and insurance.
Landlords should consider charging higher rent for dual title duplexes, which are often larger and can justify a $20 to $50 weekly rent increase, adding $1000 to $2,500 annually to your rental income.
Duplex Tenancy Structure
When renting a unique property like a duplex, carefully plan your tenancy structure to ensure a steady income.
Ideally, both sides should be rented, but if that’s not possible, stagger the tenancy end dates to maintain at least one income stream.
Avoid leaving your property vacant, as ongoing costs like mortgage payments, rates, and other fees can turn it into a financial burden.
Living in a Duplex and renting out the other side
Renting out property can be complex, especially with duplexes. In Queensland, duplexes have either single or dual titles. Dual title duplexes incur higher costs due to separate fees for rates, water, and insurance.
However, consider if the shared living conditions will be suitable for you and your family.
Repair, clean and upgrade your duplex before renting your property
Your duplex’s presentation is crucial for maximizing rental returns. Before advertising, ensure it looks its best by sprucing up the garden, repainting, and cleaning carpets. Complete major repairs and upgrades while the property is vacant.
Tenants are willing to pay more for older properties as long as they are well-maintained and look fresh. High-quality photos are essential, so consider professional photography and staging and styling services to showcase your duplex effectively.
Affinity Property offers a staging and styling service to help you get the most when you sell or lease your duplex investment property.
Getting compatible tenants
Leasing a duplex requires careful tenant selection, as neighbours need to be a good match.
Consider the lifestyle of each tenant—for instance, a family with young children may not pair well with university students. Taking the time to vet tenants ensures a harmonious living environment, reduces turnover, and helps keep your letting costs down.
A good tenant relationship is key to a successful duplex rental.

Benefits of buying a duplex in Brisbane
There are many good reasons to buy a duplex in Brisbane. Whether you’re investing, buying your first home, or looking to downsize. Duplexes can deliver great benefits.

Buy both sides, rent one out
When you buy a duplex, you have many options available to you. You can rent out both sides concurrently; live in one side while renting out the other; or live in one side and invite a friend or family member to live next door. Due to their flexibility, duplexes are becoming more popular among extended families.

Buy one side, save money
Purchasing only one side of a duplex is a great way to own property without spending a fortune. For example, one side of a duplex may cost less than $400,000. This is significantly cheaper than buying a detached house with the same design.

Turn a single title duplex into a dual title duplex
Dual title involves two separate lots that generally share common property. It’s permitted in certain zones to increase residential density, but not all areas are suitable. Depending on the location, you may need Council approval. Affinity can look after the strata title process for you.

Duplex properties can exist in different formats and configurations. There are so many options, including single storey, side-by-side units, or two-storey duplexes where the units sit on top of each other. Smaller duplexes tend to have lower valuations and lower sale prices. On the other hand, large duplexes generally enjoy far greater investment returns.

Purchasing a duplex as an investment property?
Before investing in a duplex, plan your strategy carefully. Ensure the suburb is experiencing population growth and does not have an oversupply of duplexes.
