Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Organization	Business and Organization W. P. Carey Inc. (“W. P. Carey” or the “Company”) is a REIT that, together with our consolidated subsidiaries, invests primarily in operationally-critical, single-tenant commercial real estate properties located in the United States and Europe that are leased on a long-term basis. We earn revenue principally by leasing the properties we own to companies on a triple-net lease basis, which generally requires each tenant to pay the costs associated with operating and maintaining the property. Founded in 1973, our shares of common stock are listed on the New York Stock Exchange under the symbol “WPC.” We elected to be taxed as a REIT under Section 856 through 860 of the Internal Revenue Code effective as of February 15, 2012. As a REIT, we are not subject to federal income taxes on income and gains that we distribute to our stockholders as long as we satisfy certain requirements, principally relating to the nature of our income and the level of our distributions, as well as other factors. We also own real property in jurisdictions outside the United States through foreign subsidiaries and are subject to income taxes on our pre-tax income earned from properties in such countries. Lease revenues from our real estate investments generate the vast majority of our earnings. We invest primarily in commercial properties located in the United States and Europe, which are leased to companies on a triple-net lease basis. At June 30, 2026, our portfolio comprised our full or partial ownership interests in 1,748 properties, totaling approximately 188 million square feet, substantially all of which were net leased to 384 tenants, with a weighted-average lease term of 12.2 years and an occupancy rate of 98.5%. In addition, at June 30, 2026, our portfolio comprised five operating properties, including four hotels and one student housing property, totaling approximately 0.5 million square feet. During the six months ended June 30, 2026, we sold our 11 remaining self-storage operating properties (Note 14). We operate as one reportable segment. Our business is characterized as investing primarily in operationally-critical, single-tenant commercial real estate properties that are principally leased on a long-term basis. These economic characteristics are similar across various property types, geographic locations, and industries in which our tenants operate and therefore considered one operating segment. Our consolidated operating results, including net income, are regularly reviewed, in the aggregate, by our chief operating decision maker (“CODM”) to evaluate performance and allocate resources, which can be found on our consolidated financial statements. Our revenues are largely derived from the long-term leases that we execute with tenants. These revenues are classified as either Lease revenues (Note 4) or Income from finance leases and loans receivable (Note 5) in accordance with Accounting Standards Codification (“ASC”) 842, Leases. Our operating expenses are regularly reviewed by our CODM. All expenses are reviewed, but our CODM is regularly provided with the following significant expenses, which are included in our consolidated financial statements and require no additional disaggregation: General and administrative expenses, Property expenses, excluding reimbursable tenant costs, Interest expense, and Provision for income taxes.
