The Canada Pension Plan Investment Board (CPPIB) has formed a joint venture with Welltower to take a 97.5% interest in a senior housing portfolio.

The joint venture paid $555m (鈧500m) for the majority stake in six properties in Florida, known as Aston Gardens.

CPPIB is a 45% owner of the joint venture, with Ohio-based Welltower owning the remaining 55%.

Discovery Senior Living, which owns the remaining 2.5%, operates the 1,930 rental units.

Peter Ballon, managing director and head of real estate investment for the Americas at CPPIB, said: 鈥淭he Aston Gardens properties are successful because they offer high-quality accommodations, campus-like communities with resort amenities in select, sought-after locations.

鈥淭his portfolio is well-positioned to benefit from long-term demographic trends and is an attractive entry into the US seniors housing sector for CPPIB.鈥

CPPIB said Thomas DeRosa, chief executive at Welltower, provided a 鈥渓arge, global alternative capital source to the public markets鈥.
