The RPG duplex development journey: from finance to handover

Duplex investing can deliver an incredible ROI when the process behind the investment is done right.

At RPG, we’ve spent more than 30 years refining that process step by step. The result is The RPG Duplex Investment Roadmap, designed to take an investor from finance and land through to planning, construction and a tenant-ready investment.

In this video, RPG Customer Success Consultant Jo Robertson walks through the journey and explains what happens at each stage.

One Builder From Start to Finish

The first thing to understand about the RPG process: we are the builder.

That means RPG is your single source throughout the development.

We take you from finance and land through to planning, construction and handover, and we are accountable for the entire process. There is no middleman who then needs to chase another builder.

Because RPG has been refining this process for more than 30 years and focuses specifically on regional NSW, the complete journey can usually move from start to finish in around 8–10 months.

Start With Finance Pre-Approval

Before looking for the right investment, one of the smartest first steps is getting your finance pre-approved.

This gives you clarity around your borrowing capacity and puts you in a position to move quickly when the right opportunity becomes available.

If required, RPG can also connect you with a broker partner who specialises in duplex investments.

Stage 1: Acquisitions and Site Assessment

If you don’t already have land, RPG can actively source a suitable block using our knowledge of regional NSW, with a focus on growth potential and rental yield.

If you already have land, we can work with your existing block.

From there, our team completes the site assessment while our drafting and estimating specialists work towards providing a fixed price within 10 days, and often sooner.

Stage 2: A Fixed, Turn-Key Price

This is one of the most important stages for an investor.

Rather than starting with an indicative price that changes as the development progresses, RPG provides a price that is fixed, all-inclusive and locked from the start.

It is also structured to align with your finance pre-approval, so you know where you stand before progressing further.

Stages 3–5: Finance, Pre-Planning and CDC Approval

With your fixed price established, you can secure finance from a much clearer position.

Once the land has been exchanged and the preliminary agreement is in place, RPG’s in-house specialists prepare the required documentation so approvals can be lodged after settlement.

We then use the streamlined CDC pathway rather than the slower council DA process.

RPG’s CDC specialty forms part of the fixed-price turn-key package, rather than becoming another separate cost later in the project.

RPG’s existing website similarly positions fixed pricing, CDC-friendly designs and an end-to-end model as central parts of its investment process.

Stage 6: Construction to Turn-Key Handover

Once construction begins, three decades of experience come together.

Because RPG provides a fully turn-key service, we manage the development through to completion, including items such as landscaping, fencing, driveways and final finishes.

At handover, the aim is simple:

You receive the keys to a tenant-ready duplex investment.

That is The RPG Duplex Investment Roadmap.

It is a process RPG has refined over more than 30 years and continues to improve, giving investors one accountable builder and a clear pathway from finance through to handover.

Frequently asked questions

A duplex investment can improve your cash flow by providing two rental incomes from a single property. With The RPG Duplex Investment Roadmap, you’ll enjoy a cash flow-positive investment from day one—minimising risks, maximising returns, and setting you up with a steady stream of passive income
Our turn-key approach means your duplex is tenant-ready faster, helping you generate income sooner and build long-term wealth.

Yes. New duplexes can generate over $20,000 per year in depreciation deductions — far more than older properties.

That improves your cash flow and reduces your taxable income, especially in the early years of ownership.

A quote is an early estimate. It’s usually based on limited information — often before a site inspection or proper planning assessment has been done.

That means it’s subject to change. In most cases, it’s just a rough ballpark to keep the conversation going.

A fixed price, on the other hand, is contract-ready. It reflects all known costs — including siteworks, approvals, materials, and finishes. It’s the figure you can take to your lender and build with confidence.

Owning a duplex or dual-key property can set you up for a more comfortable retirement by providing a steady stream of passive income.
With two rental incomes from a single investment, you can build a reliable nest egg that keeps your finances secure and maintains your quality of life.
Through The RPG Duplex Investment Roadmap, we optimise your build specifically for investment ROI.
The process starts with a thorough site assessment and feasibility study, and a fixed price is provided within just 10 days—compared to the industry standard of 6 months. This early clarity means you can secure finance from a position of strength, avoiding market fluctuations and hidden costs.
Our turn-key construction approach, with streamlined planning and fast-tracked approvals, ensures your duplex is tenant-ready sooner, thus maximising your rental income potential.

Every step is designed from day one to protect your investment, deliver consistent cash flow, and set you up for long-term financial success.

Because without it, you’re not in a position to move forward — no matter how ready you think you are.

Pre-approval isn’t just a formality. It tells you exactly what you can borrow, so you’re not wasting time on packages that won’t work. It also puts you in a stronger negotiating position when the right opportunity comes up — because you can act immediately.

And most importantly, it means your builder can give you real advice. Without it, all they can offer is ballpark figures and generic options — and that’s how delays and budget issues start.

If you don’t know your borrowing capacity, you’re not ready to build. It’s that simple.

Ask about approvals: are they using a Complying Development Certificate (CDC) or a full Development Application (DA)? 

CDC is typically faster and less risky. 

DA can take 6–12 months — and open the door for contract repricing.

 

Ask about their pricing: is it a fixed price, or does it include Prime Costs (PCs) and Provisional Sums (PS) that allow the builder to add extra charges later?

 

And ask about their financial standing: what’s their rating under the Home Building Compensation Fund (HBCF)? 

A builder with poor HBCF capacity could leave you stranded mid-project if they collapse — and that’s not uncommon in today’s market.

Look out for Prime Cost items (like cheap allowances for appliances) and Provisional Sums (for unknown siteworks or materials).

These costs often show up later — along with a builder’s margin. RPG contracts are genuinely fixed — no allowances, no surprises.

We provide a full defect period, structural warranty and referrals to trusted local property managers in your build area.

We don’t disappear at handover — we make sure your investment is set up to perform long-term.
