Item 2. Properties

Senior Housing and Healthcare Properties

As of December 31, 2022, we owned or had investments in approximately 1,300 properties (including properties classified as held for sale), consisting of senior housing communities, medical office buildings (“MOBs”), life science, research and innovation centers, hospitals and other healthcare facilities. We had 17 properties under development, five of which are owned by unconsolidated real estate entities. We believe that maintaining a balanced portfolio of high-quality assets diversified by investment type, geographic location, asset type, tenant/operator, revenue source and operating model makes us less susceptible to single-state regulatory or reimbursement changes, regional climate events and local economic downturns and diminishes the risk that any single factor or event could materially harm our business.

As of December 31, 2022, we had $2.4 billion aggregate principal amount of mortgage loan indebtedness outstanding, secured by 105 of our properties. Excluding the portion of such indebtedness attributable to our joint venture partners, our share of mortgage loan indebtedness outstanding was $2.2 billion.

The following table provides additional information regarding the geographic diversification of our consolidated portfolio of properties as of December 31, 2022 (excluding properties owned through investments in unconsolidated real estate entities and properties classified as held for sale):
