He began my Real Estate career in 2007 with CENTURY 21 Realty Alliance in San Mateo, CA. Initially, he focused on commercial real estate and that led to many opportunities on the residential side. He now specializes in both Residential and Commercial Sales and leasing. He's assisted clients in home-buying, selling their homes and rental placements-including single family homes, multi-unit apartments, and small to high-end commercial properties. He's also sold off-market and pocket listings in the San Francisco Bay Area. Constantinos often work with renters who don't believe they can purchase a home, educating them and turning them into Home owners.
