About Gregory Costanzo

I help investors identify and maximize real estate opportunities in Costa Rica—with a focus on long-term value, energy-efficient design, and market-smart strategies. As a former licensed agent in Brooklyn, NY, I successfully leveraged my first brownstone into multiple properties, personally renovating one to Passive Haus standards for superior performance and resale value.

With a degree in electrical engineering and a hands-on approach to construction, I bring technical insight and project management skills that few agents can match. Since relocating to Costa Rica in 2023, I’ve specialized in tropical contemporary builds and energy-efficient homes tailored to the growing demand for sustainable luxury.

In addition to my real estate expertise, I’m fluent in Spanish from my years living in Argentina and speak conversational French, thanks to extended time in France—an asset for international investors seeking guidance with cross-cultural communication and local navigation.

Whether you’re looking to develop, flip, or hold, I provide on-the-ground expertise, trusted local connections, and a deep understanding of how to make investments work in the Costa Rican market. From land acquisition to design/build consulting, I’m a strategic partner at every stage of the deal.
