Common Questions

Dual Key Investment — FAQ

What exactly is a dual key investment property? +
A dual key 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.
How much capital do I need to get started? +
Less than you might think. Dual Key investing doesn't require the same capital as commercial or multi-dwelling developments. Many of our clients get started with as little as $50k–$80k in usable equity or savings, combined with a standard investment loan. We'll assess your situation on a strategy call and show you exactly what's achievable with what you have.
What rental yields can I expect from a dual key? +
Dual Key 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.
