Welltower Inc. is a real estate investment trust that owns and finances seniors housing communities, outpatient medical properties, and healthcare facilities primarily in the United States, United Kingdom, and Canada. The company generates revenue through three main channels: operating seniors housing communities directly (including independent living, assisted living, and memory care); leasing properties to healthcare operators under long-term triple-net leases where tenants pay all operating expenses; and leasing outpatient medical facilities to investment-grade healthcare providers. Welltower employs a data-science-driven investment approach to identify acquisition and development opportunities, manages relationships with dozens of operating partners, and uses standardized operational systems to enhance performance across its portfolio of thousands of properties.
