What Our Investors Are Saying

★★★★★

"Investment Bricks found us a duplex site in South-East Queensland that none of the big agencies even had listed. We're now pulling in $2,400/week across both dwellings and the land has already jumped in value. Phenomenal service."

MR

Duplex investor — Brisbane, QLD
★★★★★

"I was comparing a standard investment property vs. a duplex and Lucio laid out the numbers clearly. The duplex gave us an extra $640/week in rent on the same deposit. We went ahead and haven't looked back."

Property investor — Melbourne, VIC
★★★★★

"From first consultation to key handover in under 14 months. The whole process was smooth and Investment Bricks handled everything — finance, council, builders. Completely stress-free."

DT
David T.
Duplex investor — Adelaide, SA
★★★★★

"We used equity from our home to fund the duplex. Lucio's team helped us structure the finance correctly so we didn't have to touch our savings. The build is tenanted and cash-flow positive from day one."

★★★★★

"$68k in equity created within the first 12 months of completion. We're already talking to Investment Bricks about our second duplex. Independent advice with no hidden commissions — exactly what I was looking for."

JP
James P.
Investor — Perth, WA
★★★★★

"I was sceptical at first — every other 'property advisor' I'd spoken to pushed one developer's stock. Investment Bricks showed me 12 different sites across 4 states. That independence is priceless."

Common Questions

Duplex Investment — FAQ

What exactly is a duplex investment property? +
A duplex is a single land parcel containing two separate, self-contained dwellings — each with its own entrance, kitchen, and living areas. As an investor, you receive rental income from both dwellings, effectively doubling your income stream compared to a standard investment property on the same block.
Is duplex development legal across all Australian states? +
Yes, duplex development is legal across all Australian states, but planning rules vary by council. Key considerations include minimum lot size, R-code zoning, and setback requirements. Our roadmap outlines the state-by-state rules in detail so you know exactly where the most investor-friendly opportunities exist right now.
How much capital do I need to start a duplex investment? +
Most of our clients use a combination of equity from an existing property and cash savings. Generally, investors with $200k+ in available equity or deposit funds are well-positioned to get started. We'll assess your specific situation during a strategy call and show you exactly what's achievable.
What kind of rental yields can I expect from a duplex? +
Duplex investments in strong-demand corridors are currently delivering gross rental yields of 5.5–7.5% in many markets, compared to 3.5–4.5% for comparable single-dwelling properties. The roadmap includes real examples of current Investment Bricks projects with detailed yield breakdowns.
Do I need to manage the properties myself? +
No — Investment Bricks provides end-to-end facilitation including connections to professional property managers who specialise in dual-occupancy properties. Most of our investors are fully hands-off from the moment tenants move in.
What is the difference between a duplex and a dual-key property? +
A duplex has two fully separate dwellings on one title (or two separate titles after subdivision), while a dual-key property is technically one dwelling with an internal connecting door. Duplexes typically offer stronger rental yields and more flexibility — including the option to sell each dwelling independently after subdivision.
