It is owned by Aurora Capital Group, an L.A. private equity investment firm.

The property at 12827 Kling St. was sold Fred and Gerda Gober, of Playa Vista, to Daniel and Melanie Zermeno, of Glendale. The 7,300-square foot, garden-style apartment complex was built in 1958 and last sold in 2005 for $1.5 million. It is a mix of one- and two-bedroom units. The sellers were motivated by the desire to trade up to a non-management-intensive property, said Earle Hyman, of Marcus & Millichap’s Encino office, who represented them. The buyers sold a building in Hollywood to purchase this complex because they wanted something closer to home and in a better area. Marcus & Millichap’s Oscar Varela represented the buyers.
