Thurman, who joins from Alliance Residential Company where she was senior vice president for the Northwest, will be responsible for overseeing Raintree’s capital improvement programme.
She previously held senior positions at Riverstone Residential and Fairfield Residential.
Couwenberg most recently served as vice president of acquisitions and dispositions for Sack Properties. He started his career at CBRE as a multi-family broker, before spending nearly five years as director of investments at Equity Research.
Jason Check, managing director at Raintree Partners, said: “Ian Couwenberg and Annette Thurman are seasoned professionals with the critical skills to continue our forward momentum while maintaining our high standards of excellence.”
The appointments are intended to capitalise on and maintain Raintree’s current growth. The company now owns nearly 5,000 units in California and has recently widened its scope to acquire both small and larger properties.
According to Raintree, the firm plans to invest $23 million into portfolio-wide improvements in 2017.
Check said: “As property operators with an owner’s perspective, we recognise the opportunity to improve our assets strategically in order to grow rents, drive ongoing occupancy, and create the best resident experience possible.”
Aaron Hancock, managing director at Raintree Partners, commented: “We have been extremely active in the market in recent months, increasing our existing portfolio by 25 percent.”
He added: “We continue to draw upon our expertise in this multifamily niche in order to identify acquisition and development opportunities where we can create and maintain long-term value.”
