资产 (zīchǎn) is the broad, formal term for 'assets' in a financial or business context — anything of value owned by a person, company, or institution. It overlaps with 财产 (cáichǎn 'property, wealth'), but 资产 is more technical and used in accounting, investment, and corporate settings, while 财产 is the everyday word for personal belongings and estate. 物业 (wùyè) specifically refers to real estate property or property management.
