When a condominium in San Francisco’s Millennium Tower hit the market a decade ago, it offered a living space — and a lifestyle — that only a well-heeled buyer could hope to attain. Millennium symbolized luxury and boom time aspirations. A one-bedroom on the 15th floor fetched more than a million dollars in 2014. But the same unit sold last week for $615,000 — or $779 a square foot — a 45% decline in value in the course of 10 years. And it wasn’t the only Millennium condo whose price appeared to be in free-fall. #sanfranciscorealestate #sanfrancisco #sfrealestate #millenniumtower
