Rainier Sebastián León, Realtor & Development Strategist

RESF Inc. Founder, R&R Consulting


With a professional career spanning more than 25 years under his belt, Rainier Sebastián León parlayed his 18-year corporate career at a Fortune 50 company into a thriving real estate practice of over 16 years as an associate at RESF. Rainier Leon PA, just accredited A+ by the Better Business Bureau, has evolved through the years, adding services and market-setting sales along the way.

In 2024, his consulting services were formalized with the founding of R&R Consulting. R&R offers white-glove development strategizing and deal creation for developers and landowners. Its mission is to create off-market acquisition options according to developer clientele needs; conversely, R&R offers a discreet avenue for asset owners to sell outside the public domain.

León’s corporate career as an IT project manager for American Airlines’ U.S, Caribbean and Latin American markets yielded success on 627 projects in 44 countries. Simultaneously, he earned Top Producer status in 2015 in a part-time capacity at RESF, and he continues to do so year-to-date.

Léon starts 2024 with a deal pipeline exceeding $150M in land, office, retail and multifamily. “My clients rely on my diligence, insight and relentlessness to deliver the best investments,” he insists. “That privilege and absolute trust is my sole driver and priority over all else — personal life included.” León’s clients range from private to institutional, and small investors to larger-cap domestic companies, as well as multinational entities and celebrities.

León holds a Bachelor of Business Administration degree and a Master of Science in International Real Estate, and is currently pursuing his CCIM Designation.

“At 46 years young, I’ve learned the most powerful lessons,” he says. “Gratitude is my compass, integrity is absolute and authentic intentions will always give rise to perpetual success. My guiding mantra is that one’s evolution is limitless in all ways and every direction.”
