How One Investor Approached 30 Properties Before Turning 30 — Get the Playbook, Free

Eddie Dilleen built his property portfolio one purchase at a time — starting with far less capital than most people assume you need. In 30 Properties Before 30, he breaks down the research process, the mistakes he’d fix in hindsight, and the framework he now uses to plan every acquisition. It won’t tell you what to buy. It will show you how to think about the decision.

Property investing isn’t complicated because the market is hard. It’s complicated because nobody hands you a process.

Most first-time and next-step investors aren’t short on motivation — they’re short on a clear starting point. Between conflicting opinions online, uncertainty about borrowing capacity, and the fear of tying up years of savings in the wrong decision, it’s easy to spend more time researching than acting.

30 Properties Before 30 isn’t personal financial advice, and it won’t tell you which suburb to buy in. What it offers is a way of thinking through the decision: how to narrow down a market, what questions to ask a lender before you fall in love with a property, and how the same process that works for a first purchase can be repeated for a second, third, or fifth.

Building a Portfolio, One Decision at a Time

How Eddie approaches the sequence of purchases behind a growing portfolio, and the order of operations he considers before each one.

Researching Markets Like an Investor, Not a Browser

A practical way to shortlist locations using data points that matter, instead of scrolling listings on gut feel.

Understanding Yield, Growth and Cash Flow Together

Why looking at only one of these numbers in isolation is how avoidable mistakes happen.

The Mistakes Most Beginners Make (and How to Spot Them Early)

Common missteps in the first-purchase decision, explained plainly enough to actually apply.

Planning Your Next Purchase Before You’ve Settled the Last One

How to think about timing, serviceability and finance structure if a portfolio — not just a single property — is the goal.

Building a Research Process You Can Repeat

A simple framework for evaluating any property or market, so every future decision gets easier, not harder.

Get the framework before your next property decision.

Whether you’re weighing up your first purchase or your fifth, 30 Properties Before 30 gives you a process to work through — free, in digital or physical format.
