Buying A New Duplex As A First-Time Home

Many potential homeowners don’t consider purchasing a duplex as their first home.

However, if you’re smart when making a purchase, a duplex might be an affordable option to own a home in a preferred location or make it a real-estate investment where you can occupy the home before selling it off in the future at a profit.

This guide outlines the meaning of a duplex, how it’s advantageous for first-time homebuyers, and the potential drawbacks you need to consider before making a purchase.

Key Points

  • Generally, a duplex can be described as a single house comprising of two homes. The homes share one wall and often have a similar layout. Simply put, a duplex can be described as a house that’s divided into two homes, with each home having its own garage, yard, and entrance.


  • In case a duplex has a strata title, the two attached homes are rented or sold independently. If it doesn’t have a strata title, the two attached homes are only sold off as one block comprising of two homes.


  • Any eligible first-time homebuyer can utilize a first homeowner’s grant when buying a duplex. However, the duplex has to be new to qualify for the grant.

What’s a Duplex?

Generally, a duplex can be described as a single house built on one piece of land but is constructed to comprise two homes.

Basically, the two private homes look like mirror images of each other with respect to the layout, especially when they’re built abreast each other. In traditional duplexes, the homes usually share the central wall.

Duplexes are categorized somewhere between apartments and detached houses. Each home in a duplex features its own kitchen, bathroom, driveway, and entrance.

However, a duplex isn’t a freestanding structure. Unlike apartments, you only share the central wall with a maximum of one neighbor. 

The address of the two homes in a duplex often features the same address. For instance, one home in a duplex may have an address such as 64A whereas the other home may have its address as 64B.

When Purchasing A Duplex, Do You Buy One Or Both Homes?

While duplexes are built together, they’re not always sold off as one whole unit. The title of the house determines whether you’ll purchase one of the sides or both homes.

In case the house has a strata title, then you can buy one of the sides. However, if the house doesn’t have a strata title, both sides are sold together.

If you’ve only bought one side, you’ll own the piece of the land on which it’s built. If you purchase both sides, then you’ll own the entire piece of land.

Floor Plans for Duplexes

While traditional duplexes comprise of two homes built abreast, modern options can feature different layouts.

The layout used may affect its resale value and rental potential. Some common floor plans for duplexes include:

1. Stacked floor plan

This is a less common duplex floor plan. In stacked duplexes, each home has a private floor space, but both homes share one ceiling/floor such that one duplex sits on top of the other duplex.

Both entrances are often built to face the street. However, the top home is accessed through internal stairs.

2. Back to front floor plan

In this configuration, the two homes making up a duplex are built in a way that one home sits behind the adjoining home.

However, this setup is not appealing for most buyers since the owner of the home at the back walks past the home at the front to access their home.

3. Side by side floor plan

This is the most common duplex configuration, whereby two homes are built abreast each other.

Both homes share a central wall. Most buyers expect to invest in this duplex floor plan, making it easier to rent or sell.

Can I Use a First Homeowner’s Grant to Purchase a Duplex?

While it’s possible for a first-time homebuyer to purchase a duplex, you should ensure you meet the eligibility criteria for a first homeowner’s grant.

In most states, the grant is only applicable to new homes. Some states allow existing homes to be renovated and become eligible for the grant.

In most states, you can’t use a grant to buy existing duplexes unless they have never been occupied.

If you qualify to use a grant, you should live in your newly bought home for six or more months before you use it for investment purposes.

Alternatively, you can purchase a newly constructed home or build one from scratch and customize it the way you want.

What Makes Duplexes Great for First-Time Homebuyers?

Duplexes come with several benefits for first-time homebuyers. Here’re some of their advantages:

1. Live in the desired location

As a homebuyer, your wish is to own a home in the best location. For instance, you probably desire to reside in a suburb but don’t have enough money to build a home in such a location, you can still purchase a duplex at a lower cost.

Essentially, it costs about half to purchase one side of a duplex when compared to building a new home.

However, buying an entire duplex may cost about the same as building a freestanding house.

2. Rental options

A duplex with a strata title can be rented. You can choose to live in one of the homes and rent the other side.

Alternatively, you can rent both homes in a duplex to get more income from the same piece of land.

Thus, duplexes are appealing in the sense that you can become an investor and occupier simultaneously.

3. Save money

No matter where you’re buying a home, you can cut the cost by buying a duplex. That way, you can own a house earlier either by cash or by taking a small home loan.

This is especially possible when purchasing one of the sides rather than the entire duplex block.

4. Land value

When buying an apartment unit, you only own the home and not the land on which it’s built. However, when buying a duplex, the land on which the duplex sits becomes yours.

Thus, you’ll own property with more value, especially if you’re buying a duplex in a location where the land value is likely to appreciate with time.

5. Less maintenance

By buying one side of a duplex, it means you’ll only be responsible to maintain half of the house. Consequently, you’ll only clean your floor and maintain a smaller lawn.

Also, you’ll only handle fewer repairs. However, if you buy the entire duplex, you’ll have more maintenance work to do.

6. More privacy

Duplexes offer more privacy when compared to apartments. With apartments, you won’t have the yard to yourself.

Also, you may have neighbors surrounding all sides of the apartment. Luckily, you only share much of the space with just one neighbor when dealing with duplexes.

7. Tax breaks

If you’ve bought just one side of a duplex, you can claim some tax deductions for expenses like interest payments or repairs. Some shared costs, like building insurance, may get written off.

Disadvantages of Purchasing a Duplex

While owning a duplex comes with several advantages, it also comes with some downsides. Here’re some disadvantages of purchasing a duplex:

1. Shared insurance

Besides sharing a wall, owning one side of a duplex means that you’re also sharing the foundation and roof.

Not unless you own the entire block, you’ll get shared insurance for the building with your neighbor.

You should have an agreement with your neighbor on how to do repairs that touch any shared parts of the building.

2. Shared wall

Since you’ll be sharing the roof and wall of the duplex with your neighbor, you might have to deal with certain issues such as a noisy or messy neighbor.

Also, if you own the entire block but have rented the other side, then you might have to deal with problematic tenants.

3. Neighbor approval for renovations

If you’re planning to do some renovations, you might have to seek permission from your neighbor before going ahead with the project.

If your neighbor declines, then you’ll have challenges to do the renovations. Thus, the kind of a neighbor you’ll have will largely determine the kind of life you’ll experience in the duplex.

In most cases, you may not have control over the kind of neighbor you’ll have. Regardless, you can try to meet the neighbor before buying the duplex.

If you want to rent one of the sides of the duplex, choose the tenants carefully to avoid problems with them.

4. Tax implications

If you’re owning one of the sides and renting the other side of the duplex, you can write off some tax deductions meant for the rented side.

However, in case you decide to sell off the block in the future, you may get hit with a huge capital gain tax. The tax is based on the profit you’ll earn from selling off an investment.

5. Rental risks

There’re several risks that come with renting a property. For instance, you should be sure that you’ll get tenants if you want to rent out part of the duplex.

However, you might not be guaranteed of getting tenants.

What to Look Out For When Shopping For a Duplex

  • Consider a duplex that has matching sides- Duplexes that are symmetrical and painted with the same color on both sides are more valuable than asymmetrical duplexes.


  • Consider buying in an area that has few duplexes- An area with more duplexes means that your duplex will be less valuable. Thus, buy in an area that has few duplexes.


  • Buy a duplex with a strata title if you’re planning to sell it in the future- It’s easier to sell a duplex with two titles rather than one with a shared title.


  • Match the duplex with the market- In case you want to build a new duplex, ensure its quality and appearance match with other houses within the area.


In conclusion, whether you want to buy a standalone home, duplex, or an apartment, it’ll help to get a loan to make your first-time home purchase easier. Also, consider loans with low-interest rates to make it easier to repay the loan.
