A beachfront home in California's exclusive Malibu Colony once owned by legendary singer-songwriter Joni Mitchell has hit the market for $27 million. According to a press release from Coldwell Banker Realty, the oceanfront property stands out not only because of its celebrity connection but also because of a rare feature that would be exceptionally difficult to build under today's coastal regulations, a beachfront swimming pool and spa located just steps from the Pacific Ocean.
