RPG Duplex Investment: Secure Your Retirement, Boost Your Kids’ Future, and Build A Reliable Financial Cushion

"A duplex investment provides a steady income stream, giving you peace of mind and financial security while also ensuring future stability for your family."

You already know the potential duplex investments hold…

But with so many options out there, why should you choose RPG?

Well, we’ve spent years (30, if we’re being technical) perfecting our process to ensure that your investment meets and exceeds your expectations.

Let us show you how we’ve raised the bar in duplex and dual-key investments.

We’re not here to rush you into your golden years, but let’s be honest—you want a better retirement. 

A duplex investment can be a game-changer, helping you build a solid nest egg for a comfortable retirement. It provides a steady income stream, giving you peace of mind and financial security while also ensuring future stability for your family.

Trust us, “you from the future” will be very appreciative of the choices you make today.

But it’s not just about you. You’re probably thinking about your kids and how tough it is for them to break into the property market.

It’s challenging and expensive out there, and you’d do anything to give them a head start rather than watch them pour money into rent. With a duplex investment, you can help them buy their first home much sooner.

Plus, if the design, planning, construction, lending, and finance involved is making your head spin, we’re here to make it simple.

So, if you’ve felt like you’re missing out on life-changing investment opportunities because it all seems too complex, keep reading—this one is definitely for you.

First things first, how does RPG do duplex and dual-key investments best?


We’ve cracked the code with The RPG Duplex Investment Roadmap. This isn’t just any build process—it’s designed to take you from the planning stages through construction and beyond, giving you a reliable, long-term investment vehicle.

We know that you need rock-solid construction if you’re in it for the long haul. But here’s where we really stand out:

  • We streamline the process of pricing and approval management, helping you secure finance and start your projects much faster.
  • Our turn-key construction process is the most cost-effective and efficient you’ll find on the market today.
  • We eliminate those sneaky hidden costs that tend to pop up with duplex projects.
  • We’ve got the local know-how to spot areas in regional NSW with the best growth potential and rental yields.

RPG’s biggest advantage? Our unique pre-construction and 10-day fixed-price proposal

While most developers take about six months to give you a fixed price (which feels like forever, right?), we can lock it in within just 10 days. Yes, you read that right—10 DAYS.

So, when you choose RPG, you’re not just making a solid investment—you’re also avoiding the usual risks of price changes and market fluctuations that could mess with your loan arrangements.

Numbers speak louder than words

The proof is in the profits, and RPG’s numbers show why it’s a winning investment.

Our efficient 30-day planning process means you can start earning rental income six months sooner—because who wouldn’t want to start making money faster?

Here’s the math on how much you benefit from having tenants in 6 months earlier:

  • Earn $650 per side of your duplex
  • That’s $1,300 in weekly rent
  • Over 24 weeks, you’re looking at $31,200 in rental income

With a rental yield of 5% or higher, your investment is solid. RPG’s market-leading fixed pricing lets you secure the construction cost for:

  • A dual-key build, ranging from $550,000 to $570,000;
  • A 3-bedroom duplex build, ranging from $715,000 to $740,000; or
  • A 4-bedroom duplex build, ranging from $750,000 to $790,000.

With RPG, your investment isn’t just smart—it’s your smartest move.

What does life look like after the RPG duplex journey?

Imagine this: you’ve made a smart investment, and your financial future is secure. Retirement isn’t something to worry about anymore—it’s something to look forward to.

Your family’s taken care of, your standard of living is protected, and you can finally relax.



We all want that elusive passive income stream that builds wealth and covers costs effortlessly.

With your RPG duplex, that’s precisely what you’ve got. It’s easy to manage and a solid foundation for future growth.

But here’s the icing on the cake: you can help your son or daughter get ahead by moving them into one part of the duplex while still owning a cash-flowing investment. This sets them up in a much better position to buy their own home in the future.

All you need to think about is what you do next. Will you sit back and enjoy the rewards or expand your portfolio with more duplex investments? The choice is yours.

Sounds good, right? You can get there by following The RPG Duplex Investment Roadmap. It’s a simple, step-by-step guide to investing—no complications, just results.
