A North Miami apartment complex, Alta Mira, has been sold to Aventura-based investment firm Advenir Inc. for $52.7 million. The 240-unit community, located at 12010 N.E. 16th Ave., was once a trailer park. The property was developed by Atlanta, Georgia-based Wood Partners in 2013. The transaction was completed with a $38.7 million mortgage provided by CBRE Capital Markets. Advenir, founded in 1996, has a portfolio of roughly 7,400 units located throughout the U.S. and valued at $550 million.
