About Isaac Leiva

Isaac Leiva is a luxury real estate advisor and development specialist focused on 
Costa Rica’s South Pacific region, one of the country’s most sought-after markets 
for residential and lifestyle investment. With a background in architecture, 
construction, and real estate development, he brings a strategic, technically 
grounded perspective to every transaction. 
His approach goes beyond traditional brokerage. Isaac supports clients throughout 
the full lifecycle of a property, from acquisition and feasibility analysis to 
development potential and long-term value assessment. Rather than pushing 
transactions, his role is to help clients make well-informed decisions that are viable, 
aligned, and sustainable over time. 
Isaac regularly advises buyers, investors, and sellers on site feasibility, 
infrastructure considerations, subdivision potential, and development strategy, 
ensuring each opportunity is evaluated with rigor, discretion, and clarity. For 
property owners, he provides thoughtful positioning aligned with international 
luxury standards and global market expectations. 
Backed by the global reach and prestige of Christie’s International Real Estate, 
Isaac works alongside a trusted network of legal, technical, and design 
professionals to deliver a seamless, concierge-level experience. His clients value his 
ability to translate complexity into clear strategy focused on long-term value, sound 
execution, and confidence at every stage of the process.
