The volume for closed seniors housing property sales transactions dropped noticeably during the second quarter, according to Bill Kauffman, a senior research analyst with the National Investment Center for Seniors Housing & Care.

Seniors housing volume decreased 43%, from $1.8 billion to $1 billion, Kauffman wrote in a blog post. When compared with the second quarter of 2015, seniors housing volume decreased 79%, he added. The rolling four-quarter volume in seniors housing was down 31%, from $12.6 billion to $8.7 billion.

Fewer than 100 deals closed in seniors housing and nursing care in the second quarter, Kauffman said, a phenomenon that has not occurred since 2013. Specifically, 76 deals closed, 54 of which were single-property deals and 22 of which were portfolio transactions.

The number of deals valued at more than $1 billion also has decreased, Kauffman said, noting that the industry has not seen any deals close in the $250 million to $500 million range for the past two quarters. “Those deals have been a solid driver of activity in the past,” he wrote.
