In 2000, FINSA established a partnership with AIG Global Real Estate, the real estate development and investment management subsidiary of American International Group, Inc. (AIG). The partnership has provided FINSA with solid financial support and a global real estate perspective.

AIG Global Real Estate comprises a group of international companies within AIG Global Investment Group that invest in and actively manage over 53 million square feet of real estate assets around the world. American International Group, Inc. (AIG), world leaders in insurance and financial services, is the leading international insurance organization with operations in more than 130 countries and jurisdictions.

GE Commercial Finance is one of General Electric's largest "growth engines" and plays a key role for client businesses in over 35 countries. FINSA started operations with GECC in 1994 becoming their most important client.

Since FINSA completed the sale of a substantial size of its portfolio to Intramerica, a JV was created between Intramerica Real Estate Group, a GE Commercial Finance Real Estate subsidiary and the Arguelles Family, and FINSA has also established a partnership with Intramerica in which FINSA is responsible of their portfolio management.
