RPG Investor Case Study: Why Sheree Mason Chose a Fixed-Price Duplex Investment

For Sheree Mason, investing in a duplex was about creating greater financial freedom and building a source of income for retirement.

Her goal was to eventually use rental income to help cover her living expenses, giving her more freedom to travel and enjoy life without relying entirely on employment income.

But she wasn’t confident about managing a property development on her own.

After exploring her options, Sheree chose Residential Property Group (RPG) for its fixed-price, turn-key duplex investment process and the support provided throughout her decision-making journey.

Why Sheree Chose a Duplex Investment

Sheree wanted to make progress towards her financial goals while she was still working.

Her longer-term plan was to generate rental income for retirement, pay down her home loan and potentially continue investing in property.

A duplex appealed to her because it offered flexibility.

Depending on future market conditions and her financial position, she could consider holding both dwellings for rental income, selling one or potentially selling both.

However, Sheree had limited time and didn’t want to manage the development process herself.

RPG’s structured approach gave her the confidence to move forward without having to coordinate every stage independently.

Fixed Pricing Gave Sheree Confidence in the Numbers

One of Sheree’s biggest concerns was the possibility of unexpected construction costs.

She had heard stories about building projects exceeding their original budgets, leaving investors facing significant additional expenses.

For Sheree, understanding exactly what she was committing to was essential.

RPG outlined the construction costs, CDC-related expenses and other inclusions upfront through a fixed-price contract.

This gave her a clear understanding of the overall project cost and helped her assess whether the investment suited her financial position.

Knowing the agreed price before signing the contract was one of the biggest reasons she felt comfortable moving forward.

A Duplex Investment With Options for the Future

While Sheree’s primary goal was to build retirement income, she also wanted flexibility if her circumstances or the property market changed.

She liked the possibility of generating rental income while holding the investment, rather than having to sell at a particular time.

A duplex also offered potential resale options that aligned with her longer-term investment strategy.

For Sheree, being able to consider different outcomes gave her greater confidence in the decision.

She wasn’t simply looking at what the property might earn in rent. She was thinking about how the investment could support her financial goals as they evolved.

A Managed Building Process Without the Complexity

Before choosing RPG, Sheree had considered another duplex investment company, but that opportunity didn’t proceed.

As a first-time investor, she had plenty of questions and wanted to understand the process before committing.

Through her conversations with RPG, she felt comfortable asking questions and reviewing the information provided.

She also appreciated having the technical aspects of the development managed by an experienced building team.

With limited time available, RPG’s turn-key approach suited her circumstances.

Rather than spending hours coordinating the different stages of the development, Sheree could focus on understanding the investment and making an informed decision.

Looking Ahead: Building Towards Retirement

Sheree sees her duplex investment as part of a longer-term strategy to create financial freedom.

Her aim is to build rental income that could eventually contribute towards retirement expenses, while potentially using future investments to help reduce her home loan.

She also hopes to continue investing as her financial position develops.

For Sheree, the most important factors were understanding the total cost, having confidence in the building process and knowing she had different options for the future.

Her experience highlights why fixed-price certainty, clear information and investment flexibility matter when considering a new-build duplex.

This case study reflects Sheree’s personal investment experience and financial goals. Rental returns, resale outcomes and individual investment results may vary. The ability to sell duplex dwellings separately depends on the applicable title and subdivision arrangements.

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.
