We all know how rare $100+ million properties are. There are only a handful of them in the United States and just a tad bit more internationally. Well, I just came across this magnificent waterfront mansion located in Baltalimani, RumeliHisari, Istanbul, Turkey. It was built in the second half of the 19th century by the famous French architect Alexandre Vallaury for Müsir Zeki Pasha, who was a minister during the ruling of Sultan Abdulhamit II. This approximately 150 year-old, 5-story baroque style mansion boasts 32,292 square feet of living space with 23 bedrooms and 8 full bathrooms. There is also approximately 40,000 square feet of formal gardens and a 426' pier. It is listed at a whopping $115,000,000.
