What is a duplex?

In Queensland, a duplex consists 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. 

Duplex building design configurations

A duplex building design and its price are interconnected, and the type of duplex house on sale can vary. While they share a connecting wall, each side of a duplex has its own amenities and separate entrances. Duplex building design patterns include:

6/4/4 – 6 Bedrooms, 4 Bathrooms, 4 Car Garage. 

The example below shows a unique duplex building design for a corner lot.

Selling Single Title Duplex Property: What to Know Before a Duplex House Sale

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 separately.

Selling a Dual Title Duplex Property: What to Know About This Duplex House Design

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 duplex rental properties in Queensland requires specialist experience. Whether you are setting duplex rent for a single title property or managing a dual title duplex rental, the rules and responsibilities are different from managing a standard house.

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 tenancies. These actions reduce costs for landlords. 

Avoid the headaches of being a duplex landlord and let the experienced property management team at Affinity Property handle every stage of your duplex rental process.

We will vet potential tenants to make sure they pay rent on time and treat your duplex with respect and care. Once your tenants are living in your duplex, we will manage the day-to-day running of the property and address any issues.

The backbone of our great service is the strong bond we develop with our clients and with your tenants.

Single Title vs Dual Title for your duplex rental

Renting out property can be complex, especially with duplexes. In Queensland, a duplex house can 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 house, 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

One of the most compelling advantages of owning a duplex house is the ability to live in one side while generating rental income from the other, effectively letting your tenant help cover your mortgage repayments.

Unlike a standard family home, a duplex gives you the unique benefit of an income-producing asset built directly into your everyday living situation, all while maintaining complete privacy between both dwellings.

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 house 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.

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.

Why buy a duplex in North Brisbane?

With Brisbane CBD duplex prices above $1,200,000, many buyers are priced out of the inner city. Finding duplex homes in Brisbane is thus desirable for many potential buyers. For a more affordable option, consider areas like the Moreton Bay Region, which is poised for significant investment and growth. Buying a duplex in North Brisbane or Moreton Bay could be a smart investment. For expert advice and great deals, contact Affinity Property to discuss your duplex requirements.

Variety of configurations and options for a duplex house

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 in Brisbane or Moreton?

Before investing in a duplex, plan your strategy carefully. Ensure the suburb is experiencing population growth and does not have an oversupply of duplexes. High vacancy rates and lower property values can occur in areas with stagnant growth and too many duplexes. Consult a duplex expert to ensure you set yourself up for success.

Duplex Properties FAQs

Yes, duplexes are consistently regarded as one of Queensland’s strongest investment property types, particularly in high-growth corridors like North Brisbane and the Moreton Bay region. They offer two distinct income streams from a single land title, flexibility of use (live in one side, rent the other), and in dual title configurations, the ability to sell each side independently to maximise returns.

Duplex homes in North Brisbane have seen strong capital growth over the past decade, driven by interstate migration and infrastructure investment. The key to a successful duplex investment is choosing the right location, getting a thorough market appraisal, and working with a duplex specialist who understands the specific requirements of dual-tenancy management and strata title processes.

Duplex landlords who want to see the highest possible return on their investment should first find out what their property is worth.

First impressions count for a lot when prospective tenants see a property they might wish to live in. These days virtually everyone sees properties in photos and on the internet before they see it in person.

This is why getting professional photos and staging and styling done on your rental property is essential.

By making your property look its best, you can charge a higher rent, as tenants pay more for quality places to live.

Balancing a role as a landlord and an owner occupier can be stressful, and is not a good idea for everyone.

Before you commit to living in one side of the duplex and renting the other, you must ask yourself several questions.

  • Can you comfortably live on one side of the duplex? If you live with a large extended family including kids and elderly parents, a single side of a duplex may not be enough.
  • Do you want the extra rental returns from renting both sides of the duplex? By living on one side, you’ve cut back on the amount in rental returns you will receive.
  • Would you be comfortable sharing space with a tenant? Living so close to a tenant can become stressful when there is a dispute or other issue.

Duplex developments, better known as dual occupancy developments, are permitted in specific zones to increase residential density, but they aren’t suitable for all areas. Depending on the location, you may need Council approval. Projects that meet specific requirements may bypass the need for formal approval, while others will require a development application.

For any dual occupancy project, ensure it complies with residential zoning, and remember that building approval is a separate process.
