In-Depth Review & Analysis

Are you tired of chasing slim margins in your local market? Do you feel like the “easy money” in domestic real estate has already been made? Ronan McMahon challenges the conventional wisdom of sticking to your backyard in The Big Book of Profitable Real Estate Investing, arguing that the greatest fortunes are found by following “big unstoppable trends” across the globe.

McMahon, a seasoned international real estate scout and founder of Real Estate Trend Alert (RETA), serves as both a [Mindset] coach and a [Strategy] guide. He dismantles the fear associated with international investing, reframing it not as a risky gamble, but as a logical pursuit of value. His narrative is compelling: why settle for 4% returns in a saturated market when you can achieve double-digit yields and rapid appreciation by identifying the next Cabo or Costa Rica before the masses arrive?.

The book is built on a foundation of actionable [Strategy]. McMahon introduces concepts like the “Path of Progress”—investing in areas where new infrastructure (airports, highways) is set to unlock value. He champions the use of leverage, not just through traditional mortgages, but through developer financing and seller carrybacks—often accessed through private networks that uncover off-market opportunities most investors never see.

However, this isn’t just a book of theory. It’s packed with [Tools]—specific checklists for due diligence, formulas for calculating yield, and even a “rolodex” of contacts for RETA members. While some sections inevitably pitch his membership service, the underlying education on vetting developers, understanding market cycles, and managing foreign assets is invaluable for any investor willing to widen their horizon.

If you’re ready to stop thinking locally and start profiting globally, McMahon’s playbook offers a clear, exciting, and surprisingly practical roadmap.

• Impactful Quote: “The time to buy is not necessarily when there is literally blood on the streets. It might be…or it might be several years into the crisis.”
