We're investors, developers and advisors — not theorists!
The strategies we recommend to clients are the same strategies we're continuing to use to build our personal portfolios.

Everything from strategy to search and on to settlement
We are investors, developers and advisors who practise what we preach. Every strategy we recommend is one we use in our own portfolios.
When you work with Prosperitii, you’re not just hiring a buyers agent — you’re partnering with a team of professional investors who know how to find, negotiate and secure properties that actually create wealth.
Every service is built around one goal: continued wealth creation, cash flow to affordably keep you in the game, and micro development sites that deliver equity uplift and long-term growth.
We specialise in finding micro development sites that allow everyday investors to create wealth faster — either by adding cash flow today and holding for the future, or by manufacturing equity and profits right from the start.
Whether you're buying your first investment or scaling your portfolio with micro developments, our mission is to help you make smarter decisions, avoid costly mistakes, secure your financial stability and accelerate your financial independence.
Talk strategy with usFour things we'll never compromise on
We know our markets
We work where the planning reforms have created the best micro development and cash flow opportunities across NSW, the ACT and QLD. We’ve physically spent time in these areas — walked the streets, inspected the properties, and done the research ourselves. We know which streets work and which ones don’t, and we buy in these markets for our own portfolios.
We're planning-led
We don't just look at listings. We overlay planning rules, zoning changes, development codes and market trends to uncover sites others miss.
We practise what we preach
Every property we recommend meets strict cash flow, feasibility and capital growth benchmarks — because we would only recommend deals we'd invest in ourselves.
We make complex simple
Planning policy can seem overwhelming. We do the analysis, then translate it into plain language so you know exactly what you’re looking at and why it matters. Our clients are families building wealth, not developers — and we make sure it feels that way.
"The entire experience has been seamless"
Neil, Sonja and the Prosperitii team have been exceptional to work with. They guided us through the process of securing an investment property and loan with absolute professionalism, honesty, and care.
We're extremely grateful and wouldn't hesitate to recommend Prosperitii to anyone looking for efficient, knowledgeable property advisers or mortgage brokers. The entire experience has been seamless and we'll definitely be working with Prosperitii again.
