Home types

Two homes, one block: duplex and dual-key.

A duplex or dual-key home earns two rents from a single parcel of land. Pearson Bros Homes develops these as completed, turnkey properties across South-East Queensland, finished and ready to settle, so you can buy a dual-income asset under a single contract of sale.

Duplex vs dual-key: the difference

A duplex is two separate dwellings joined on one block, usually on two titles, so each side can be leased or sold independently. A dual-key is a single dwelling on one title, divided into two self-contained, separately lockable parts that share a roofline and one set of services. Both give you two rental incomes from one block; the duplex is generally two titles you could split later, while the dual-key stays one title and one transaction.

In short:

Duplex. Two dwellings, typically two titles, two front doors. More flexibility to sell or finance each side separately down the track.
Dual-key. One title, one dwelling, two lockable tenancies behind it. Simpler to own and manage, and a single contract of sale.
Shared upside. Either way you collect two rents from one land purchase, one set of council rates and one insurance policy.

Why investors choose dual income

The appeal is straightforward: two rents from one block usually lift gross rental yield above a comparable standalone house, while you still buy a single parcel of land and carry one set of holding costs. Two tenancies also spread your risk, so a single vacancy does not stop all of the rent.

Tenant demand across South-East Queensland is tight. Greater Brisbane rental vacancy sat at around 0.9 percent in May 2026, well below the level usually considered a balanced rental market, with gross yields of about 3.1 percent on houses and 3.9 percent on units region-wide.

New builds and the tax rules

Treat the following as proposed, not settled law. Under the Government's Treasury Laws Amendment (Tax Reform No.1) Bill 2026, introduced 28 May 2026 and not yet passed the Senate, negative-gearing limits would apply to established dwellings bought after 12 May 2026 from the 2027-28 year, while new builds are proposed to be preserved. The same Bill proposes changing the 50 percent CGT discount from 1 July 2027, again with new builds treated more favourably and able to opt in.

Because this is a Bill that could change before it becomes law, do not rely on it as fixed. A brand-new duplex or dual-key falls on the new-build side of the proposed rules, but how that applies to you depends on your circumstances, so confirm the current position with your accountant.

Also built for families

Dual income is not only an investor play. A duplex or dual-key suits multi-generational living: a family can occupy one side and house parents or adult children in the other, or live in one and rent the second to help cover the mortgage. Both parts are private and self-contained, with their own entry, kitchen and bathroom, under one roof.

How Pearson Bros Homes delivers it

We develop completed, turnkey duplex and dual-key homes across our South-East Queensland corridors and finish them before they are listed. By the time you buy, it is a ready-to-lease asset sold under a single contract of sale at a fixed price, with no progress payments and no build wait. Every home is built by FRD Homes (QBCC licence 15046435) to the NCC 7-Star energy standard, carries a 7-year structural warranty under the QBCC Home Warranty Scheme, and includes a 12-month post-handover maintenance period.

That is the difference from build-to-order house-and-land in these corridors, where you sign two contracts and wait out a build. With a finished home you settle on a normal property timeline of about 30 to 60 days and lease it, or move in, now.

Frequently asked questions

What's the difference between a duplex and a dual-key?

A duplex is two separate dwellings joined on one block, usually on two titles, so each side can be sold or leased on its own. A dual-key home is a single dwelling on one title divided into two self-contained, separately lockable parts that share a roofline and one set of services. Both deliver two rental incomes from one land parcel; the practical difference is that a duplex is generally two titles you could split later, while a dual-key stays one title and one transaction.

Why do investors choose dual-income homes?

A duplex or dual-key earns two rents from a single block, which typically lifts gross rental yield above a comparable standalone house while keeping one land purchase, one set of rates and one insurance policy. With Greater Brisbane rental vacancy around 0.9 percent in May 2026 (SQM Research via PropertyUpdate), tenant demand across South-East Queensland is strong. Two tenancies can also soften the impact of a single vacancy. Whether the numbers suit you depends on your goals and finances, so confirm with your accountant or financial adviser.

Do new builds keep negative gearing?

Treat this as proposed, not settled law. Under the Government's Treasury Laws Amendment (Tax Reform No.1) Bill 2026, introduced 28 May 2026 and not yet passed the Senate, negative-gearing limits would apply to established dwellings bought after 12 May 2026 from 2027-28, while new builds are proposed to be preserved. The Bill also proposes changing the 50 percent CGT discount from 1 July 2027, again with new builds treated more favourably. Because this is a Bill that could change before it becomes law, confirm the current rules and your own position with your accountant.
